I just learned, in an embarrassing way, that I need to brush up on my advanced SQL querying skills!
I kind of blew it on an interview test - writing advanced SQL queries. I couldn't remember some of the syntax, nor how to do some functions with join queries...
Oh well, yet another avenue for self-training :-) It's just a matter of refreshing my memory!
At least I can do basic SQL!!!
