Gene:

which everone is used in production. If the statements are dynamically built with "variable" hard-coded values then you have a couple options.

1)      Tune the query for the worst case
2)      Tune the query for bind-variables and set "cursor_sharing = force"

in your init.ora

Hi,

I'm trying to tune a query which has several input parameters. I used the bind variables in their place to create an explain plan. Then I put some real data in their place and created another explain plan. The two plans were different. Which plan should I be using in my tuning? The one with the bind vars or the one with the real data?

TIA Gene
