kotlin-jpa-specification-dsl VS SQLDelight

If you are using Kotlin, kotlin-jpa-specification-dsl provides a very convenient way to generate Specifications from KPropertys.

This seems to be similar to https://github.com/cashapp/sqldelight, and I've always wanted a python equivalent!

In typescript, there are query builders (not talking about ORMs) that can basically do this within the type system, but that would be infeasible in python's type system. This approach (type/code generation is a good alternative, though I like using sqlalchemy / alembic to manage schemas/migrations.

One thing I'm curious about is how it knows the types of columns? I looked quickly at the Readme but didn't see it (probably a parameter somewhere I missed).

That functionality has existed for almost exactly a year

- SQLDelight - great experience overall, the only issue that I found, was when that I made a database migration that worked on Android, but not on iOS (https://github.com/cashapp/sqldelight/issues/3812)

Database - SQLDelight

room is a great example but like I said our data is kotlin-only so we tend to use libraries like sqlDelight.

This seems similar to https://cashapp.github.io/sqldelight/ for kotlin, I think this approach is pretty neat, good luck with it!

Sounds like you want what SQLDelite offers, but for TypeScript. SQLDelite is only for Kotlin and SQLite though.

SQLDelight had neat built in support for this

You would really like sqldelight[1] then. It takes the concept of an ORM and flips it on its head. Instead of mapping function calls to SQL statements, it lets you write SQL statements and then generates classes for you that have methods for those statements.

For instance, you could have a SQL statement like getCardsForFight: select * from fights where cardId = ? and titleFight = ?, and it would generate a class that has a method getCardsForFight(cardId: number, titleFight: number).
