I wish writing SQL queries was more popular than ORMs (lemmy.ml)

Some backend libraries let you write SQL queries as they are and deliver them to the database. They still handle making the connection, pooling, etc.

ORMs introduce a different API for making SQL queries, with the aim to make it easier. But I find them always subpar to SQL, and often times they miss advanced features (and sometimes not even those advanced).

It also means every time I use a ORM, I have to learn this ORM's API.

SQL is already a high level language abstracting inner workings of the database. So I find the promise of ease of use not to beat SQL. And I don't like abstracting an already high level abstraction.

Alright, I admit, there are a few advantages:

  • if I don't know SQL and don't plan on learning it, it is easier to learn a ORM
  • if I want better out of the box syntax highlighting (as SQL queries may be interpreted as pure strings)
  • if I want to use structures similar to my programming language (classes, functions, etc).

But ultimately I find these benefits far outweighed by the benefits of pure sql.

You miss the major reason of an orm, abstract vendor specif syntax, i.e. dialect and derived languages such as pl sql, t-sql, etc.

Orm are supposed to allow you to be vendor agnostic

I'm always curious about this particular feature/argument. From the aspect of "i can unit test easier because the interface is abstracted, so I can test with no database." Great. (though there would be a debate on time saved with tests versus live production efficiency lost on badly formed automatic SQL code)

For anything else, I have to wonder how often applications have actual back-end technologies change to that degree. "How many times in your career did you actually replace MSSQL with Oracle?" Because in 30 years of professional coding for me, it has been never. If you have that big of a change, you are probably changing the core language/version and OS being hosted on, so everything changes.

Some of us have had to support multiple database targets. So I don't know about changing a database in a running application, but a good abstraction has made it easier to extend support and add clients when we could quickly and easily add new database providerz
