If you like learning random tips & tricks, there’s a great discussion going on in Reddit:
I’m only going to give away the first one just to get you started: if you need to repeatedly comment and un-comment groups of code, do this:
-- /* First line. Removing the two dashes activates the block comment
Where name = 'Whatever'
-- */ Last line. When the block comment is on, this terminates it
When you want to comment the whole thing out, just remove the top two dashes. You don’t have to put in the ending */ because it’s already there at the end, just silently getting ignored until it’s needed.
GENIUS. Head over to the Reddit thread for more.
