Whatcha want to know?
What would you like to see covered in a future post in the SQL 101 (or 201) series? I'm full of ideas (among other things), but there's not much point in posting things ya'll aren't looking for...
If there's something that's always been sorta fuzzy, let me know and I'll do my best to translate it for you in plain 'ol English. Just post a comment and away we go.
