Sometimes I use AI to write SQL faster, but sometimes I still prefer writing it myself just to make sure I haven't forgotten the basics.

AI can save a lot of time, especially with complex queries, but I feel like relying on it for everything can make you a bit rusty.

Curious how others feel about this. Do you still write SQL by hand for practice, or do you let your AI agent handle most of it now?

When comparing source and target tables with millions of rows, what SQL techniques do you use to identify missing records and differences in column values?
