What exactly do you need to know about SQL when working with a framework?

Question

PHP

I want to know what exactly you need to know about SQL when working with various php frameworks.

Answer 1

same as without framework

Answer 2

The less you know, the more likely you are to win a prize for the slowest app. And you can also implement in code what the database engine does well.

Answer 3

You need to know that, as a rule, at first everything will be cool and fabulous (ORM magic and all that), and then, when it turns out that you need to take a step to the left or right (something more complicated than from standard examples), you can stumble upon a whole bunch of problems, rakes, crutches, etc. Up to complete despair and reading articles like "why ORM is evil", etc.
And SQL itself will still need to be known. Any custom things will turn into a wall of misunderstanding on the part of any framework.

Answer 4

If the application is large-scale, then the framework's ORM may simply not pull and then the application will fall. In such cases, you have to build everything yourself.
