If you are after the n'th degree performance then the: for x in (select ... )
will be minisculely faster (simply because its slightly less code and plsql is interpreted). And unless I have a particular need for the cursor %attributes, or the cursor needs to be passed around I prefer the sql directly in the for-loop. I don't have to hunt up through the procedure/package to find the cursor definition, and (subjectively) I find it easier to read. hth connor --- Tim Gorman <[EMAIL PROTECTED]> wrote: > Both use cursors, but a FOR loop is more concise > coding.
