Answer Posted / tdguy
Refer the explain plan. 1. check for product or nested
joins and try to avoid those joins, as they affect the
performance. 2. try to check the confidence levels of TD.
Collect stats for the columns recommended by TD. 3. In case
of long queries, try to use SI appropriately. Should be
carefully chosen. 4. Check for the usage of temporary
tables. These tables can be used in case any aggregrate
results are needed.
