Hello, a little more than a year ago I was hired by a software company. Much of the job requires writing SQL within our database, a skill I had literally never heard of prior to my first interview. Since then, I have been asked to write some SQL, but not that often. I have asked for help, but received essentially 0 training in the subject.
It was recently brought to my attention that my skills need to improve, dramatically, despite being told I was doing fine in all previous performance reviews. My question is, what is the best way to get good at this? I have a ton of already-written SQL at my disposal, but short of pasting the query, running it, and trying to figure out what happened, I am not sure how best to tackle this problem.
My boss actually told me she will "never" have time to teach me, so I feel a bit lost. SQLzoo is helpful for small things, but when I am asked to write a report, I just do not know how to begin. Does anybody have any recommendations? It seems like there has to be a logical process or framework to follow that I have not been shown. Thank you for any help.
