Me:Types of SQL Injection

Mom:U r in engineering?Right?So why are u studying types of Injections?

Me:🤦‍♂️😂😂

There’s a SQL joke in there somewhere

SQL injection in nutshell

Searching SQL with no index.

I remember some years ago when a professor asked -
"What is the difference between SQL and MySQL?"

And one of the students answered -
Uh... I don't know... SQL is more like a general SQL and MySQL is a personal SQL...

Just found out there's a legit Dutch DJ call "SQL".
Guess what type of posts he's being tagged in mostly?

SQL injection

When you see a web service API accepting a SQL query in one of its JSON fields and the evil starts growing within you..

DROP ALL DATABASES

Just because you can!

When you're a sql request that has done it's job

Some mouthwatering SQL right here

Why did the SQL query stop working?
.
..
...
....
.....
It was part of a UNION.

Lol this guy literally asked me to use My OWN sql

You know you've had to deal with a tough database problem at work when you start seeing SQL in your own kitchen... (It says SOL meaning salt)

When 1=1-- works in SQL injection

So today my gf wanted to know if I, a software developer, know anything about SQL.

Adorable. 😍

We had issues with lack of disk space on our production SQL server. Another developer decided to delete the databases he thought weren't in use to clear some space.

Ever think about checking first?!

Production chaos!

A SQL clause walks into a bar, he sees two tables and asks: "can I join you?"

3 SQL Databases went into a NoSQL Bar.
After a while, they walked out because
.
.
They couldn't find tables there.

Discovered one of the worst db designs ever:

- A cust is inserted in a table.
- The insert trigger is fired, calling a stored proc
- The stored proc being called creates a dynamic sql that builds a create table statement for 8 different tables. These tables will be postfixed with the newly-created cust id and is executed.

When querying info for a cust, a stored proc is used that accepts an id value would be appended to another dynamic sql that creates a select statement across all 8 tables for one customer.

Shoot me now.

I recalled a seemingly simple task I took on.

We were building a booking system, and I had to figure out how to retrieve bookings by a certain date range.

Upfront, the tasked seemed simple until I realised I had to both figure out the logic and the SQL statements needed to retrieve all bookings within a certain date range in one query.

I ended up drawing a model to help me visualise the various date-range criteria to be satisfied. And used unit tests to help me think through each date range criterion and make sure they were accurate. Some were obviously from paranoia, but better to be safe than sorry...

After that, I had wrote down raw SQL directly into Sequel Pro first to make sure my query logic was accurate too, before translating into something the ORM equivalent. This was when I learned how to define and use variables in SQL. The variables were throw-away code; I just didn't want to have to hard-code the test date-ranges over and over again; minimise chances of spelling errors.

Needless to say, felt my problem-solving skills went up one level after this task. Saw my coding style and unit tests improve. And also the thought processes that go into how to maintain code quality...

This fucking stupid asshole developer, wrote every single SQL execution with string formatting. Made me a full sleepless night fixing this shit. Isn’t this a classical SQL injection sample?

4 years ago, during our college, a friend of mine was explaining us about hacking using simple SQL injections. He showed us some of the sites he hacked. Out of curiosity we tried it on college internal website it worked. We had access to all the details of all the students in university, and even the lecturer's information. We informed the management , they were shocked on seeing this. They had just spent 25 lakhs for this website couple of months ago.

It bothers me more than it should when people pronounce sql as sequel.

1. Buy a road
2. Name it after an sql injection
3. Have mail delivered to you
4. ...
5. Profit... I guess?

me: oh you can add a where clause to filter xxx out with your group by.

arrogant junior: whuuut? you can use where clause with group by ? No u can't!

me: err... yes you can...

arrogant junior: NO!!!! No it doesn't work that way!

me : okay okay... fine ...

**30 mins later**

i see a where clause in the sql statement lol...I don't know why this person is always so pissed and fierce lol

> TeamLeader1: I just discovered SQL is actually super fast! The low responsiveness I've experienced comes from our ORM!
> IHateForALiving: well of course SQL is blazingly fast. SQL has been refined by the best engineers in the world for the past 50 years, its performances are unparalleled for everything you could possibly need, unless you want to scale REALLY big. Sequelize, instead, is an Active Record ORM, so it's bound to struggle with huge amount of data, because every single row will get attached a significant amount of black magic to make sure everything syncs correctly. Why is that?
> TeamLeader1: I have a problem with this frontend component, it doesn't allow pagination. I tried downloading the whole DB to bypass that, but the ORM is slow... so I will bypass the ORM and download the whole table with a raw query. Look at that! It works like a charm, it's super duper fast!'

This mf is downloading some 35 thousand rows every time some user loads a page because he doesn't know how to paginate the fucking table with Angular, there's no way these people are real.

SQL relationship in real life 😅😂😂

Someone wanted to test if the I-Scout game was capable of preventing SQL injections 😂😂

The I-Scout game is by the way an indoor and outdoor game for scouts all over the globe..

My Database Teacher writes the SQL commands in lowercase. It really grinds my gears.

Easy cop out for people who wrote code vulenerable to SQL injection: It's not a bug, it's a feature that let's users search using SQL syntax.

SQL just feels like its screaming at me....

Got hired as an SSRS engineer. Walked into work day 1 thinking I was a bad ass with my SQL joes2pros knowledge and quickly (and i mean quickly) got smacked down with what real SQL procs look like........should've renamed my title to SSRS reverse-engineer. Good times.

According to my predecessor, nothing showcases your SQL skills quite like generating the entire page (markup, JavaScript and all) from a single 2500 line query.

Dear weird stackoverflow,

What SQL knowledge do I need to hack devRant and get an avatar on here ?

Hah!

Where is the location of hell for bad SQL devs?

NO "WHERE"

Two sql databases enter a nosql bar. After 10 min they exit because they couldn't find a table

so guys, how do you say SQL? "sequel" or "es-kyu-el"?

I hate SQL Server so much, don't matter how Microsoft say they improve themselves at SQL Server.

There's a lot of fucking bloat, messes your system and your services, adds tons of crap in your system registry, while more advanced SQL engines such MariaDB/PostgreSQL are more contained, and its very small.

Why SQL Server has to mess with Windows' ACL and his own privilege systems?.

Uninstall it and a lot of components remain hidden and tons of registry entries, not even TotalUninstaller or CCleaner can help.

I hate it since my technical high school and my goddamn college is forcing us to use SQL Sever for EVERYTHING, instead of good alternatives, messed my computer entirely requiring to format.

I try always to convince my freelance clients to use open-source alternatives, and say how SQL Server is so crap, (i had variant degrees of success).

COTD : SQL Joins !

I was to optimise a SQL query (7 min to execute,yes) with around 20 joins (I did not write this). Checked for missing indexes,etc.. but nothing worked. Stared outside the window, and back to desk reordered the joins ,executed in 10 secs.

Honestly the same for me always looking up how to do a SQL join.

Nothing like a SQL Script failing and fucking up an important Database right before my christmas vacation...

Thanks for syntax highlighting that, firefox! I spent almost 10mins checking the parentheses and trying different combos...

Today in a meeting, a non-dev analyst who frequently uses SQL mentioned in passing that he uses Excel as a text editor for his SQL code. I don't know what he said after that because I wasn't able to get past the fact that Excel is his go to text editor.

Using Oracle 10g for our distributed databases practical lab session, and typed many SQL queries in one sheet.
Suddenly this guy came and told shortcut 'ctrl + r' to quickly run selected query.
And the page fucking reloaded and boom, all queries were gone! His evil laugh was more disturbing. 😡😡
Fuck him.

Hired a new BI developer. She tested reasonably ok in SQL, and certainly showed good strengths in visualising data, plus had a good attitude in the interview. We hired her. She broke her laptop the first day. We got her another then she complained the camera didn't work but didn't realise the lever in front of the camera was to move the privacy shutter off and on.

Assigned her some work of taking queries that are used in a BI tool that targets the transactional database directly, and re-jigging them for Snowflake which we're using as a data warehouse now, aggregating all our data into one place. Yet, she's struggling to understand why the SQL query she's pasted in doesn't work as-is.

I go over it again; the source schemas and tables are this, but in Snowflake we've named them this. She then bemoans how much work that is to change them all - I say use find and replace. She then struggles with Snowflake syntax errors and asks for a guide on T-SQL to Snowflake. I show her Google and say "this is what I did when I hit these problems - search for 'Snowflake equivalent to T-SQL getdate()' or 'how to get current date in Snowflake' but she still doesn't understand. I ask if she's every had to work between T-SQL and MySQL or MySQL and PostgreSQL or Oracle and so on and she says yes. I say the syntax isn't the same, is it? And she goes oh, now I understand.

She scored reasonably in her SQL test but I'm now concerned there's something fundamental missing in her grasp of SQL. I gave her a detailed demo of the tools, I explained in the interview and on her start about our move to a data warehouse for all our apps, and put her through some training plus gave her time to work through our Confluence pages - not expecting she'll remember everything, but more to ensure she recalls they exist and what the general contents are.

Anyhow, that's my rant.

SQL Rule 1. Always assume there are external processes that might affect your data. (for instance, triggers).
SQL Rule 2. In Denormalised data, never execute logic on dependant table values, always copy from the parent.
SQL Rule 3. When Denormalised data schemas are created the DBA knows what they are doing.
SQL Rule 3.1. If DBA knows what they is doing then according to Rule 1 there is no problem with adding in some triggers to maintain data clones as they are created.
SQL Rule 4. If you don't like or agree with triggers, deal with it. They are a first class tool in a first class RDBMS. In a multi-app or service environment there may be many other external processes massaging your data
SQL Rule 5. If all previous rules are not broken and the system has been running efficiently for many years DO NOT complain that there are triggers in the database that are doing and have been doing the same process that you just butchered (by violating Rule 1 and 2) in your makeshift "hello world, look what I can do from my phone" angular BS when the rest of the users are still relying on the existing runtime app.
SQL Rule 6. If you turn my triggers off, you sure as hell better turn them back on!

Writing sql queries on production server makes me nervous.

You know that you're working too long with SQL Server when you enter your password somewhere and press F5

So, part of my job is working with SQL. Not my favorite technology to work with. But the tables have mostly non-descript fields, multiple schemas in the same table, and encoded relationships spanning multiple tables. Yes, the database from hell! On top of that, there is very little documentation on this mess. -- And my boss wants me to write queries against a combination of these tables to make sure the program is working. RIGHT...

BI dev: Hey, can you help me with my SQL query?
Me: Sure, let me see it.
BI dev: sends screenshot - not even the whole query, literally a screenshot with a segment of text in it. No errors showing either.

SQL & Assembly: The most intuitive languages I have used

In our databases lesson, we are going to use Microsoft SQL Server throughout the year.

This shit's setup fails at random, doesn't even start (empty error box??????) on some machines, and when it, uh, works, kinda, it's a convoluted mess.

Help.

I knew I had found the right group of friends when one of them suggested we try SQL Injection on the instant messaging feature of the bowling alley console.

Unrelated, do people not think, "hmm, that seems like an unnecessary feature?"

GitHub and SQL pickup lines.

A SQL query goes into a bar, walks up to two tables and asks, "Can I join you?"

No matter how logically clean and simple your SQL code is, test your data....TEST YOUR DATA.

Conversations with SQL Server:

Me: TRUNCATE TABLE users;

SQLServer: Okie dokie, Command(s) completed successfully

Me: WTF SQL, u didn't even ask for confirmation

SQLServer: Well, you did type 'TRUNCATE' then 'TABLE' then 'users' didn't you. I mean how much confirmation do you need you prick.

I thought SQL was supposed to be very easy? I'd like to jump off a balcony right now because of it ...

I have quite a few of these so I'm doing a series.

A backend developer was tired of building data for the templates. So he created a macro/filter for our in house template lexer. This filter allowed the web designers (didn't really call them frond end devs yet back then) could just at an SQL statement in the templates.

The macro had no safe argument parsing and the designers knew basic SQL but did not know about SQL Injection and used string concatination to insert all kinds of user and request data in the queries.
Two months after this novel feature was introduced we had SQL injections all over the place when some piece of input was missing but worse the whole product was riddled with SQLi vulnerabilities.

The day after I delivered a secure programming course to our junior devs.

Junior dev: I can't figure out what's happening when I generate this sql.

Me: what do you mean generating ... It should be a prepared statement..

Junior dev: no I'm just generating the strings from the form

Me: ... Let's try this again....

This may be the best Stack Overflow comment I have seen when learning SQL.
How old is Frank? I don't know (null).
How old is Shirley? I don't know (null).
Are Frank and Shirley the same age?
Correct answer should be "I don't know" (null), not "no", as Frank and Shirley mightbe the same age, we simply don't know

I saw a great movie about databases today -- I can't wait for the SQL.

I'm getting really good at SQL, last year it appeared me to be very difficult but finally, it's easier than I thought

What is it about SQL that invites people to do things in utterly ridiculous ways? The amount of pointless repetition and complete lack of clarity in the query scripts I get handed is irritating at the best of times - without any documentation (or even a bare comment sometimes) how am I supposed to work out what you were doing?

Made a SQL query wich perfectly worked. Than added one collumn to be selected and everything is shit.

And the worst is I still don't know why! Ò_Ó

WHERE 1 = 1

Building dynamic SQL since 1987

I feel ridiculous. While learning SQL databases I ran a query that was supposed to fill up the database with test data for me to play with. The actual result?

8 GB and 330,000+ rows.

Keep in mind this database is on a remote server, so trying to delete it times out after thirty minutes. I’m submitting a ticket right now.

LINQ to SQL is for people who can't write actual SQL.

Unnamed SQL constraints are the devil.

Please, please for the sake of your born/unborn child, check whether the names of the entity attributes are not valid sql keywords.

Oracle SQL Errors are an absolute fucking joke, ORA-GO-FUCK-YOUR-SELF.

Thank you for coming to my ted talk.

Whole class: makes an sql database using phpmyadmin. Simple, easy, meets the requirements
Me: fuck it. Use python with pyqt5. And Microsoft sql server Spend unnecessary hours on making repetitive functions, cause my stupid ass can't figure out how to pass more than one parameters in class methods.
All in all, it looks good. I feel like I did something, learnt something new. Took on a challenge. Its a wierdly good feeling, somewhat rewarding.

I never knew that I was a good mentor at SQL , specially at PL/SQL.

I gave a task to a new member of my team, to fill 5 tables with data from other 15 tables.

I informed him well about data table info and structure. He spended about 3 days to create 25 different queries in order to fill 5 tables.

After I saw the 25 queries, I told him, that he could do it with 1 main query and 5 insert statements.

So I spended 1 hour of training, in order to build,run and explain how to create the best sql statements for this task.

(First 5 minutes)
It was looking so simple at the beginning from starting with 1 simple join, after some steps he lost my actions.

(Rest 55 minutes)
I was explained the sql statements I 've created and how Oracle works.

Now , every time he meets me, he feels so thankful for learning him all those Oracle sql tips in 1 hour.

Now he is working only with big data and he loves the sql.

Ok so I was fetching some JSON data from a SQL database server and loading it on the front-end. Every single data is being loaded onto the table except for a single data column, which is empty.

Hmmm... So I go and check my code... everything looks fine.
Then I console.log the JSON (using .stringify() of course), all the values from the table are present in the printed out JSON.

Ok, now I am really pissed.

Long story short...
I had misplaced a single 'i' in the SQL statement, I had included the 'í' (the i-acute) character instead. And since I was using an alias in the query statement, no error was shown.

Turns out we doing SQL in CS now.
Not gonna lie it's...surprisingly easy(?).

Running SQL Activity Monitor to find inefficient queries. According to legecy team this is how they think they should query SQL 2014 for a customer.

Starting learning SQL, now...~ ✨😊

Just came across this gem. What's wrong with it??

Yes, the threat of SQL injection here is a legit response, but in this particular case that's not the answer I'm looking for.

Hint: This method gets called a lot!

Any good resources for sql?

Im getting heavy into databases. Im a noob but i need to reach top level quickly.

Im gonna buy 1 oelr 2 books. Im leaning towards oreillys “learning sql“.

Any suggestions?

Creates PHP scripts for development SQL server, pushes to production to find out the schemas are different. *face palm*

been looking at my sql code all day, got headache afterwards

I'm interviewing with the data architect in two weeks' time, a self-proclaimed ninja. The chap has done PL/SQL development on SQL Server 2008 according to his LinkedIn profile. Yeah, okaaay...

Does anyone else find it super-confusing how Microsoft refers to SQL Server versions by both product year and version number?

For instance, we primarily use SQL Server 2012, 2014, and 2017, which are versions 11, 12, and 14 respectively.

The slight mismatch between the product year and the version number creates a lot of ambiguity. If someone refers to SQL Server "14," we always have to double-check: do you mean 14 as in version 14 as in 2017, or 14 as in 2014 as in version 12? Does SQL Server "12" mean 12 as in version 12 as in 2014, or 12 as in 2012 as in version 11? It's ridiculous!

When used properly No-SQL databases are an incredible resource but my employer keeps hammering them in problems which could better be solved by traditional SQL databases in an attempt to be more "hip" and "cool".

This causes huge PITA in making the database work properly with the ORM we're using and waste of time since we're force to emulate basic features which are already exists in almost any SQL database (i.e. relational integrity) using No-SQL storage.

Today I wrote a SQL query with 7 joins. What's your record?

Starting out as a developer: I don't know why people are so stingy about tags on Stack overflow

Now: This guy tagged this question with SQL Server but is asking about Postgres I don't know how to help this guy out

writing sql at 3AM is so much fun.

Writing SQL queries in a controller should be illegal! 🙄

I just dealt with a 3 nested "if" statements in SQL. There is no indentation so I am quite frustrated since each "if" spans up to 2-30 lines.

I now understand why Python white space is significant

Company A: Oh yes we work with this huge tech company all the time and our APIs are just amazingly well made! DONT WORRY!

Company B: Yeah we've worked together once or twice and nothing seemed to go wrong the last time. DONT WORRY!

Reality: 11 API warnings, no data transfer and a SQL error meaning nothing I've been working on actually worked. #Rantover

Who has replaced a dot with a semicolon while composing a SQL query in php? Me. 😤😤😤😤😤
Two hours spent in fixing everything and a sleepless night.

Looks like copying large file e.g. 1GB from Remote Desktop Connection will also affect SQL Server performance and somehow slowing down the SQL transaction 100000x times

What a new thing to experience😆

FORMAT YOUR EFFING SQL!
There we go, much better.

(I highly recommend to you to not read this, it's just something that I had been wanting to take off my head; seriously, if you want to read it, do it at your own risk, because it will be a huge waste of your time)

Oracle Academy is the worst crappy attempt from a Corporation to create a learning platform.

The directive and academic personnel of my faculty decided that it could be a good idea to teach SQL and PL/SQL during whatever online classes will last with Oracle Academy, and I truly strongly believe (including most of my friends and classmates) that it's one of the worst ideas that could be done.

At that platform you simply don't learn shit, you read page by page of shitty PPT-like PDF presentations (that most of those are from a decade ago and other from 5 years ago) that are a pain in the ass to read due to how poorly formatted they are or how it explains badly certain concepts due to how badly made some explaining examples are, and then at each section of the "Learning Course" I have to do a Quiz that asks theorical questions and tells you to make certain code reviews to see if something is wrong or not (also which they are just alike the presentations, poorly formatted, up to the point that those have many syntax errors that end up consufing anyone a lot) and the main problem with the quizes is that also the Oracle's PL/SQL Docs are so fucking badly made, that I have to check PDF by PDF and page by page the concept that I just forgot to see how to answer the goddamn question; I mean, there are Doc pages that are way better structured and obviusly external to Oracle, but not even those pages fully cover certain SQL and PL/SQL concepts.

Seriously though, who could be so fucking ill-minded to create a shittyful learning platform and not try to fucking improve nor enhance it at least every 2 fucking years, so the goddamn "learning" process isn't that stressful.

A SQL query goes into a bar, walks up to two tables and asks, "Can I join you?"

Yesterday, microsoft showed me once again, what it means to "obey".

I tried to install Microsoft SQL Server 2012 on a virtual machine with OS Windows7.
The installation-center asked me to choose an installation-folder for SQL-Server.
No matter what, for any folder i had chosen for the installation, the setup replied with the errormessage "The installation-folder is invalid"

So i considered asking our platform-services team, whether they gave me administrative rights for the vm.
They did. I had full access to the components of my vm.

After a few days i finally recognized, that i had picked a wrong iso for the installation of sql server.

Instead of sql server 2012 + Service Pack 3, i picked sql server 2012 ServicePack 3.

So after all, Microsoft tried to tell me by showing the message "The installation-folder is invalid", that the setup weren't able to find an installation of Microsoft SQL Server 2012.

God damned!!1!

Couple of SQL databases walked into a "noSQL" bar.
But after some time they walk out...

As they couldn't find a Table... :)

Any advice on some good SQL book or resources?

I need to start learning DB designing and theory.

I know jackshit apart from the basic commands.

Today salesmen gave me some recommendations about my "so hardly optimized" SQL queries..suggestin me to change em.. I said okay, let's execute these.. 10 hours later, their computers sql workbenches finally displayed the fucking first one.

Result: 0 row... 🤐

Well well well.
Story time.

Since we are working from home for the past 4 months, I finally decided to install a Microsoft SQL server on my home server. (Mostly was using Azure)

My server is running Windows Server 2012 R2.
Tried installing SQL 2019 : fail, 2016 : Fail, 2012 : Fail. Some obscure message about some DLLs not being at right version. (And a warning that it is no recommended to install SQL server on domain controller, but I know, it is my home setup, not roduction)

“Ok fine, I’ll install it on my PC instead”. Windows 10 PC. NOPE. “Cannot install on a compressed drive”. Welp, wtf ? (Of course you cannot select destination install folder, I could’ve put it on another drive).

So here I am. Working 100% on Windows, installed Ubuntu server 20 LTS in Hyper-V, Installed Microsoft SQL server on it (BTW, install is very easy compared to windows). And that shit is working. And new “Terminal” app does support SSH out of box, no need to add Putty !

So as a Windows user, I needed Linux to make Microsoft SQL techno work.

Nothing will ever surprise me anymore. (BTW it’s fucking fast. I like SQL server on Linux)

We have so much pl/sql at our company and it really sucks because the "young" generation of devs must convince the pl/sql guys to switch to some more powerful and newer languages like java.

But not everyone wants to use the new stuff or learn anything new. I mean there are some programmers who really appreciate that there is new stuff. They have no problem learning from the younger generation. But some of them just resist any change in that direction, and thats the much higher amount of devs.

Does anyone of you have such experience? What can i do against that?
Is that some kind of "i am too old for this"-trip?

The intellisense in SQL Server only appears about 20% of the time.

Well SQL is literally love...

dude 1: Why is the sql sentence so slow? How can I improve it?
dude 2: buy more ram memory to database server

Did you hear about the followup to the database movie? It's a really great SQL

Any code should be simple and easy to read / understand.

I just reworked an old stored SQL proc.

Went from 102 lines to ... 10.

More I code, more I realize that maintainability, readability, comments and unit tests are more important than actual code. (And performances ofc. But if 1 line code does it in 1 second and 500 lines code in 0.2 seconds, I’ll take one line solution every time)

When it comes to choosing a database,  What is the best for a Java project?

1.SQL - MySQL
2.NoSQL- MongoDB

1 problem down, 3 more show up.
I love SQL.

In other news, client won't send data to utilize, so I must fill in dummy data.

How's your day?

Captains Log:

Day 2 of trying to get SQL database to work with JDBC application.

I've built a try/catch method and it throws up the message that IntelliJ can't find the JDBC driver.

More research to be done. My first officer duck buddy has no input for me.

It's going to be a long day.

Part of my job requires me to use SQL in SQL Server and databases and Python and utilising Javascript APIs - so I was thrown in at the deep end. But my fiancé is also an amazing help as a software engineer he helps to spot my errors and encourages me to take on new challenges.

Today is SQL day.

Been some time since I had to go here, the queries are flooding back to my mind like water over a dam wall. How the heck I remembered these is what I pondered.

Oh well, back to SQL (at a client - yay).

Now you SQL me, now you don't.

Jira: code formatting vs SQL. AYFKM?

Can't create a new SQL database on Azure on on one subscription as every region is unavailable. Everything works on my other subscription.

Fucking hell.

My Technical lead always asks one question to new interviewing candidates. "Write a SQL query to find the second highest salary from employee salary table". It's the same question which he faced in one interview and he didn't have answered it.
Sorry for my bad English..

SQL queries related questions in SO are so full of redundant LEFT JOINs.

Just saw this question on quora asking if saying ess-kew-ell is an indication that someone doesn't know SQL. I say SQL because there's no goddamn ee or kwell in there YOU'RE ADDING LETTERS THAT AREN'T THERE BUT SOMEHOW I'M THE MORON?!?!?!

Made a typo when create a new view in t-sql
It's completely fucked now 🤦‍♂️

I've alway pronounced it sequel but everyone I know swears it's SQL, so I say that now to fit in.

I feel like a spy, lying to my closest friends everyday...

I made changes to an SQL view used as the source for a pretty important integration that is built and managed by an external company. The integration failed the morning after and I was immediately blamed by the company and heard "how could you be so careless" and "how long have you worked in this business". I've been a programmer for 20+ years and done integrations for 15+ years. I know I checked the output of the view and it was identical in every way to before my changes.

After finally getting access to the integration code on "the other side" I found that it didn't read from the SQL view - it read the view definition. It also uncommented anything in the view (yes, uncommented) and ran that query.
We now have a year free of charge - which we won't need because my boss is throwing the company out as soon as we have a replacement.

Got my “Certificate” for SQL. What do you think? I have a few other just not sure if this means jack squat despite it being a free “certification”.

Me : So cool ! My new graphQL APIs are working so good !
Also me : ‘order by <text field> take 50 skip 10000’
Me : Hmmmm.. 2.3 SEDCONDS ?! WTF. Let’s add an index !
SQL : Sorry bro, can’t add index on nvrachar(max).
Me: OK. Here you go, you are nvrachar(128) now. Add my index !
SQL : Ok
GraphQl :<same query > Here : 90 milliseconds
Me : ‘order by <text field> desc take 50 skip 10000’
GraphQL : Sorry bro : 3 seconds. (Yes, slower than without any index)
Me : Do I fu7cking need to manually add ASC and DESC indexes ? WTF IS GOING ON !
I should’ve learnt a bit more about databases. ☹. And now I don’t have time to refactor a prod database as “needed” .
/me needs to buy DB audit. Company is still a bit small to have a DBA full time.

SQL collation conflicts are the worst thing that has ever been made possible in humanity... it's 1000 times worse than problems with time zones, change my mind.

Fuck off whoever decided to make hundreds of different versions of the same languages.

Life of an Oracle Developer ... Day {I've lost bloody count now}

Task: Optimise a 236 line cursor consisting of 7 SQL SELECTS and unions, 39 joins and nested sub queries galore.

"YAYYY" said no one ever ...

I once saw a DBA using two for loops in PL/SQL to join two tables. I wonder if he knew about the "alternative" way to do that...

I use mySQL workbench on a daily basis, but I've been having issues with the dark GTK theme not working well with Linux. Should I do a workaround to get workbench to use a light GTK theme, learn to use SQL from the CLI, or go with a third option?

I've always found it funny when sql errors "at or near" a character. I don't know enough about sql to understand why it does that (although I'm sure there a reason!)....but it just sounds like it's not trying hard enough 😂

Maybe someone smarter can explain?

That feeling when you debug the Users table in sql, which has a Password field encrypted with hash, but most of the demo users use the same Adminadmin password, so you recognize the other users password because you rembered the hash

SQL Server Management Studio: I noticed you forcefully closed the application. Do you want to recover the queries you were working on before you closed?

Me: No

SSMS: Well here you go anyway

Me: *spends 5 minutes recovering and closing files*

I was reading a few interesting postgreSQL solutions to constrain polymorphic tables (anti-pattern, I know) when something caught my eye.
Some solutions were looked down upon (or looked favorably upon) based on their portability to other rdbms like MySQL.
Is that really so important? I get it, if somehow you decide to change from one to the other for some god-forsaken reason it will make the switch easier. But really, how often will that happen?
I feel there is a tendency to just avoid using SQL beyond the basics.

i am not a SQL expert, but i can do what i need to do in order to be considered a full stack dev

the syntax i have to learn was deprecated before i was even born

copying field data from one table to another,

wondering why the execution takes so long,

since your copying only data from three rows,

realising you forgot the WHERE clause in the SQL while working on a live database and overwriting all data with the last statement 😨

So a SQL server walks into a bar to grab a drink. He gets his drink and spots a table with two people sitting down with a spare chair. So he walks up to them and says "Hey, can I JOIN you two?"

Should I learn a database language before backend, or vice versa? I’m thinking that I learning Rails and some form of SQL.

Do you feel that good too when you find the perfect (any)SQL query?
I feel sooo satisfied!

First exam this year, about database optimisation. I have been there just a week and I really enjoy this school

BUT. THIS. CAN'T. BE. TOLERATED.

I wouldn't wish my worst enemy to write SQL on paper goddamnit!!!!

(Yeah I didn't have any other pen that this red one, at least it was erasable)

Today I had to explay to a new developer, gradueated in Informatic, that our 15 year old php application uses global variables and strings as sql commands.
It seem to force someone to prostitution.
It's just like to drive a ferrari using a double-clutching because the gear is not syncronized.
I was shamed.

Is there ever any reason for SINGLE Hibernate SQL query/template to join like 10 different tables, do math, and come out to like 30 lines?

This is not a stored procedure, it's a single SELECT

Learnt a lesson today:

Never try out new hotkeys in a SQL query editor window.

Or if you do, at least make sure it's not connected to anything important :)

I was trying out new hotkeys and accidentally executed a SQL deploy script to rename something in multiple stored procedures in a large system.

Thankfully - so I saw after my heart stopped - it was only our QA db so not too bad, just a couple of devs set back.

Who woulda thought ctrl-l would execute :O

Are sql joins a bad practice? :o
I recently did some work on a page for a site ive never worked on cause my boss told me to. So they recently added product detail video urls to a table that has a relationship to the products table. The existing code was querying for the products on that said page and then during the loop that was outputting the products ,there was another query for getting the url for the current iteration/product. Told my coworker that this imo was pretty inefficient way to do it and switched it to a join and did 1 query then output that but his words were "The way it is now maybe ineffecient in your opinion but it works. Also combining inner joins with left or right is not a good practice. If the data is changed upstream the entire query would need to be redone to accommodate the change". Mind you that they query views a lot which are all made from queries that use joins and I'm also pretty sure these views were written by someone who used to be here because these guys are not good at sql or at least that's what there queries show. I'm at the point now where I'm realizing that my boss and this other guy don't give a fuck about efficiency or doing things the right way they just want it "to work". So this coworker changed my query back to the way it was because he said it broke the shopping cart even though that was already broken when I started... What is life? Maybe I'm the stupid one?

Knowing SQL does not mean knowing all the existing technologies that uses SQL, motherfucker! Stop bragging around that you know Postgres, SQL Server, Oracle and shit.

IT is full of shit talkers and ego, NNNNNNNNNGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

I've solved hard problems before, and used languages other than Java, but for some reason I don't know how to start using SQL. I couldn't find a SQL IDE. Any suggestions on how to start working with SQL on a Linux computer?

Tomorrow I'm forced to attend an in person "advanced SQL training", nothing against SQL or my company's good intentions but it's naive to expect which people would retain much after a single, super intensive 8 hour session.

A SQL statement goes to a restaurant ... there he sees 2 TABLES and asks " can i JOIN u two guys ? " :P

a sql query goes to a restaurant walks up to 2 tables and says , "can i join you"

Gosh!! Do not want to look at my shitty face in the mirror when i get to know that there is a DESC syntax in SQL for sorting data automatically even after i manually finished sorting them in Php.. #Fuckmylife #newbie

When your about to start development on some tickets you've been wanting to finish, and then MS SQL management studio poops out and you have to spend the entire day re-installing/fixing your SQL DB's... Oh and now behind schedule

Disappointment of the day- Spaces in column names of tables in SQL!!

How long do you guys tend to keep SQL migration scripts around?

Obviously they don't use up much disk space, but they do start to create clutter in a project

I recently heard someone pronounce SQL as "Sequel". Is that actually the correct pronunciation? Have I been saying it wrong all those years?

I thought Notepad++ was the one and only text editor for random small tasks..
I wanted to check a 280MB SQL file if it dumped a specific table.. the file never opened, and now npp is stuck in "Not responding" :)

Wow...a talented developer created a 3 via SQL execution plan. The query runs like crap but the execution plan art is pretty.

Found an infinite loop in SQL. One proc called another and then that one called the other. Woooooo.....

A SQL query goes into a bar, walks up to two tables and asks, "Can I join you?"

Spent 2 days optimizing SQL queries, and then I learned a valuable lesson.

If your database size is bigger than the RAM of the machine it’s running on, every query will take 5+ seconds ☹️

For some reason we store IP addresses as nvarchar(100) in SQL.

Why it is such a pain to scan nullable types on Golang database.sql

Now I have to chose between:

1- Using temporaty variable to hold the nullable value just to soon after check and set the zero value if it is null

2- Adding coalesce to my sql query for the zero values.

Did I mention that there are around 20 collumns that are nullable...

MFW I, a junior dev who just started have to explain what sql injection is to a senior IT person... It's not like I'm an expert in the field, but a little bit of expertise would be nice

Hey all, can you guys recommend some great books on database theory and design. Something aimed towards intermediate towards advanced. It doesn't have to be sql, I just want to learn how to make a kick a#@ db.
Thanks!!!!!!!

I was scanning over a dreadful code base I had to work on and found SQL injection vulnerabilities. THE SITE WAS LAUNCHED IN 2017!!!! 😢

Saw the following SQL in an SP at work:

Type_ID = CASE Product.Type_ID
WHEN 1 THEN 1
WHEN 2 THEN 1
WHEN 3 THEN 2
WHEN 4 THEN 3
END

Seems a little bit redundant to me :-)...
