Re: Astonished by embedded sql

- SQL is a set oriented language and that means a cursor
- positioned updates neead a cursor and are mostly much faster, than searched updates
- working without commitment controll, you should use a cursor for all updates, otherwise its not safe for anything

in other words: there is nothing wrong with a cursor!

D*B

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?
