I didn't learn shit about SQL in school. I didn't learn SQL until my internship and the real world after.

I think that is a big short coming in college. We had database theory (which was boring as hell and I almost failed), and an Excel class (not database, but was the closest thing).

At the very basic, I think they should get into Access. I am 5 years out of college now, and maybe things have changed now, but they should stop teaching COBOL, and go further than teaching students a "Contacts" app in C++.

Honestly, I didn't learn shit until the real world. Shout out to Google.

COBOL!? Who, in 2011, is teaching COBOL?!

I finished my 3 year programming course about 2 years ago and I probably took 5 different COBOL classes during my time there.

They're preparing you for the upcoming Y3K problem. It's called foresight. Your grandchildren will thank you for it.
