Sean, I'd be happy to hear any suggestions re: perf improvement.


The first suggestion is to remove the while loop that is replacing multiple spaces with one. Jeff Moden has a very clever of way doing this with no loop.

The second would be to get rid of the cursor if possible. Of course we only have a portion of the actual code since the cursor is declared but never referenced again.

WHILE: Agreed. However, this sproc is called for Inserts and updates an average of 10x/day, so the perf hit is probably not noticeable.

As for the cursor, there are 2 related sprocs called for each row in hierarchy affected by a change in a keyword, each having some rather complex logic.

(I will NOT share the nested! cursor! solution we use to retrieve and present the keywords and data to which they are linked. But it generally runs in under 1 second, 20K times a day).

Thanks!
