Discussion on: You Can Do it in SQL, Stop Writing Extra Code for it

Company I work for has exactly this issue. Literally all the logic (sometimes even presentational logic) is done in the database.

This is nightmare to maintain and now really difficult to refactor.

Also it's difficult to test SQL code due to lack of tools.

Probably as most of you agree it is a bad practice due to:

  • cannot track code in DVCS like git
  • cannot test DB code
  • a lot harder to scale

It is better to convenience the devs and mgmt to slowly move it out if possible.

First one is not true.

We successfully version database code using Git, have working pull requests, continuous integration and delivery.

Second is not true as well. For instance, T-SQL code can be tested using tSQLt framework. Yet again. This is more difficult and not a widely adopted practice, but it's possible and companies do it.

But in any case. Even though things are possible and can be done in database, it doesn't mean it should be.

Database testing is a nightmare I hope to never repeat. Just because a thing can be done do not mean that it should be done.

It's not true in anyway that DB code is hard to test. As long as the person is aware of DB based code units it's just the same.

Maybe you are right!
