I know sql pretty well, but every once in a while doing things like percentiles come up where I don't remember the exact incantations to get the window syntax right. Things like this can save some googling and documentation reading. I can read it to see if it makes sense, and execute it. I can create tests for the output to verify. Can save a lot of time. If it's wrong, I use the fallback of googling for examples.
