I haven't done SQL in ages but I've been forced to use it a bit more lately and I'm not very good at it. I read a basic SQL 2005 book, but I'm having a hell of a time with more complex queries. I managed to get some of them to work but they are largely inefficient. Anyone have any recommendations on good books or tutorials to help with complex SQL queries?
I'd appreciate it, thanks!
