Sorry, to clarify, not everything is in all caps. I'll append my prefered syntax below
WITH foo AS (
SELECT id, baz.binid
FROM
bar
JOIN baz
ON bar.id = baz.barid
)
SELECT bin.name, bin.id AS binid
FROM
foo
JOIN bin
foo.binid = bin.id
The above is some dirt simple SQL, when you get into report construction things get very complicated and it pays off to make sure the simple stuff is expressive.
I believe this has been proven. It's because capital letters all have the same shape whereas lower case letters do not. So your brain can take shortcuts to reading lower case but cannot with upper case.
Also most if not all editors will highlight SQL keywords so it's probably not too hard to discern SQL commands and everything else in modern day.
It's an English literacy thing - we have several non-native English speakers and using only singular avoids making those folks' lives harder. Besides it's really nice to autopilot that categoryid is a foreign key to the category table. It also simplifies always plural words... I haven't yet written CREATE TABLE pants but if I ever do there's zero chance of me creating a pantid.
Practically, you want to capitalise the commands anyway.
It gives your code some gravitas. Always remember that when you're writing SQL statements you're speaking Ancient Words of Power.
Does that JavaScript framework that got invented 2 weeks ago by some snot-nosed kid need Words of Power? No. Does the database that has been chugging on for decades upon decades need Words of Power? Yes. Words of Power and all the due respect.
My God, that's hilarious, thank you for sharing it. I enjoyed "I am like the Statue of Liberty: I accept everyone, even the wretched and the huddled and people who enjoy Haskell."
The phrase "SQL programmers" is so fucking weird. SQL isn't a programming language. It's a query language. You don't "program" things with SQL. You utilize SQL as a component of programs for data insertion and lookup, but the actual logic of execution is done in a programming language. Unless you're doing Oracle PL/SQL, in which case why are you giving money to Oracle?
Your knowledge of data engineering may be limited. SQL is predominant in data processing nowadays. FOSS tools such as DBT allows to write efficient data processing pipelines with SQL and some YAML config without the need for a general purpose coding language.
Why would anyone want that? Because SQL has the interesting property of describing the result you want rather than describing how to compute it. So you can put inside the database, a query engine with decades of optimizations, that will make a much better job at finding the best execution plan than the average developer.
It also means it's easier to train people for data processing nowadays.
T-SQL is turing complete. While the MS SQL server has limitations on OS level operations, if you allow yourself some leeway with CLR wrappers for the win32 API, there's no reason I can think of you wouldn't be able to get the database engine to be a webserver reacting to incoming requests on port 80, or drawing GUIs based off of table state.
This doesn't make sense to me. SPs and functions are in every major database. If I wrote a bash script that runs like a program, and sounds like a program, did I program it? Script it?
And lots of systems have nested logic in the DB, optimization often leads to that to reduce overhead. Unless you're being lazy with an ORM like prisma that can't even join properly.
Getting high performing queries is just as difficult as any other programming language, and should be treated as such. Even Lemmy's huge performance increases to .18ish came from big PG optimizations.
It seems to be about yelling at others that "you're not a real programmer!!!" mixed with being so "technically correct" my eyes can no longer roll the same way they used to.
Admittedly, this discussion is more one of semantics than anything. It's pretty clear I'm arguing that SQL is not a "General Purpose Language," and that proficiency in that domain is what constitutes programming. Which, yeah, is arguably somewhat arbitrary. But my point is that, colloquially, someone who only works with SQL isn't a programmer. Data Engineer, sure. DBA. Also, sure. Depends on what you do. Programmer? Not really. Not unless you (as in the person, not "it's theoretically possible") can use raw SQL to read in video data from a linux system device file and then encode it to mp4 and just nobody's told me.
LaTeX being called "programming" I can see, but I've never heard someone try to justify Markdown as programming. It's just formalizing things people were already doing to format text in plain text files into approximately half of a standard.
So is Tex. And, yet, I still don't put it under the "programming languages I know" section on my resume. Probably because it's not a programming language.
Why not? It sounds like you haven't written any OLAP queries :)
I've written ETL data pipelines using a system similar to Apache Airflow, where most of the logic is in SQL (either Presto or Apache Spark) with small pieces of Python to glue things together. Queries that are thousands of lines long that take ~30 minutes to run and do all sorts of transformations to the data. They run once per day, overnight. I'd definitely call that programming.
Most database systems support stored procedures, which are just like functions - you give them some input and they give you some output and/or perform some side effects.
MS SQL Server has this thing called Replication. It's a feature to keep tables in sync between databases, and even database servers. There's merge replication (two way), snapshot replication (one way scheduled publishing), and transaction replication (one way live-ish publishing).
And the logic is all implemented in T-SQL stored procedures.
As a senior query writer, I use caps for begin and end and some other commands, but all caps makes my head hurt. It's like the sql is screaming at me. I think it's more important to have good looking queries with proper indentation.
I write it in lowercase but then the auto-formatter we use at work converts it to uppercase when I save the file.
I love auto formatters. Prettier (the initial version for JS) really popularized the concept. If the coding style is automated where possible (things like tabs vs spaces, tab width, line wrap at 80/100/120 characters, where to put line breaks in long statements, etc), it ensures the entire codebase is consistent, and I can jump between different code bases with different coding styles without having to think too much about it.
