I don't want to learn your garbage query language
This is a bit of a rant but I really don't like software that invents its own query language. There's a trillion different ORMs out there. Another trillion databases with their own query language. Another trillion SaaS products where the only way to query is to learn some random query DSL they made up.
I just want my SQL back. It's a language everyone understands, it's been around since the seventies, and it's reasonably standardized. It's easy to read, and can be used by anyone, from business people to engineers.
Instead, I have to learn a bunch of garbage query languages because everyone keeps trying to reinvent the wheel.
Take ORMs. Their alleged benefit is they cut down development time. But instead of writing SQL which everyone knows, I now have to scroll back and forth in some ORM documentation to figure out how to write my queries. On top of that, I have to spend time debugging why the ORM translated my query into some monstrosity that joins 17 tables using a full table scan. Instead of sticking to SQL, where it's reasonably easy to argue about the performance (try to stick to
where clauses on indexed columns, don't go bananas with
joins, et cetera), I have to deal with this opaque translation layer that obscures the exact query. And I end up with bloated higher level data classes rather than easy to understand tuples or dicts that contain the data in a dumb simple format that is trivial to introspect.
Not to mention there's like five thousand ORMs out there, so instead of learning SQL once, I have to learn 34 different ORMs. It's not like people learn an ORM instead of learning SQL anyway.
And all these SaaS products. Just to pick some tools from my company's stack:
What's worse than data silos? Data silos that invent their own query language.
To be fair, some of these are SQL flavors, or at least pretends to be, but all with their own quirks that forces me to unlearn everything I knew about SQL to the point that it might as well be something completely different.
What am I asking for? Not a whole lot. Just that:
- Every SaaS product should offer a plug-and-play thing so that I can copy all the data back into my own SQL-based database (in my case, Postgres/Redshift). I don't want to use their custom made DSL. Maybe European Union can mandate this as the next step after their PSD2 open banking directive.
- There should be a 30 year moratorium on inventing new query languages.
- Let's dispel with the myth that ORMs make code cleaner. Join the embedded-SQL movement and discover a much more readable, much more straightforward way to query databases.
That's it. I realize I sound like a old crank but that's a risk I'll take.
