Hi!
Is there a possible way for looping through the records of a table(like using foreach - oracle)?

RE: loop in ms sql 2000

Yes it's called a FETCH cursor.  99% of the time it's better to not use a cursor in SQL Server.  SQL Server processes data is a ROWSET faster than a fetch cursor.

CODE

DECLARE @name as nvarchar(128)
DECLARE MyCursor CURSOR FOR SELECT name from sysdatabases
open MyCursor
FETCH NEXT FROM MyCursor into @name
WHILE @@FETCH_STATUS = 0
BEGIN
     --Do something with the variable here.
     FETCH NEXT FROM MyCursor into @name
END
CLOSE MyCursor
DEALLOCATE MyCursor

What's the end result that you are trying to get to?

I'm trying to select some rows that fulfill a certain condition.For each row,I want to gather some information and use it...

RE: loop in ms sql 2000

In that case carry on with your cursor.  That would pretty much be one of the few cases where cursors are probably going to be needed.
