Which SQL electives should I choose?

I am currently an MCSE and I want to learn SQL and get my MCDBA. My question is what electives are most recomended? I don’t know if taking Visual Fox Pro or which Visual Basic would be best. I keep thinking what it would be like if I chose to take an elective other than TCP/IP for my MCSE ( I found it key to my understanding of NT), but in that situation I had someone to guide me through, here I do not. Any suggestions would be most appreciated. Thanks
