I'm supposed to replace a Crystal Reports developer at work in 2 weeks. The thing is, I have 0 knowledge of Crystal Reports, and about "select * from parts" knowledge of SQL. I'm pretty sure I need a very firm grasp of both. What's the best way to go about learning as much as I can about SQL? I mean, I've written the "select * from <table> where <column> = <condition> order by <column>", but seriously that's the only thing I've done so far. I know about joins and unions, but right now it's more of a "learn what you NEED"
