Programming should not really be thought of as an amalgamation of different tips, tricks, and hacks. But also, I would be wrong to deny the power of tips, tricks, and hacks. They are an important piece of the pie. And every once in a while you are just missing one crucial piece of information to get you where you need to be.
The frontend world in particular seems to have an affinity for these nuggets of knowledge (a la CSS-tricks). I also see a lot of helpful tips and tricks with terminal, bash aliases, git, certain hotkey combinations, etc.
Today, however, I am coming to you today from the SQL world. Hopefully this trick will be as helpful to you as it has been to me.
Once in a blue moon there arises some business logic that seems like it might be impossible for SQL to solve—or, perhaps more accurately, the solutions that are coming to mind just seem to be too complex, or messy, and you don’t want to deal with them.
I was in this situation not too long ago, and the end result of that situation ended up in me adding a new tool to my SQL toolbelt. And it was so simple that I felt like people needed to have easier access to it!
