However, remember my motto, "If you're using a cursor you're
probably doing something wrong."  You might see the term RBAR
thrown about when it comes to cursors, especially in MS SQL
Server forums.

RBAR stands for Row-By-Agonizing-Row.

There are a few places where you have to use cursors, but
this isn't one of them!

Charles, I used a cursor a couple of times when learning embedded sql. But now I never see an advantage for using one. When <would> it be a the right place?

Anyplace there's no other way. :)

Good example, an RPG program that creates a spool file. You're going
to need a cursor. Another example, when you use embedded SQL to get
records for display in a subfile.

I'm not following your first question.
