Re: Same Query, same database, same application, new plan from one environment but not from another

<snip>

10g stores previous version of stats for 30 days by default, you can revert stats to see if the better performing plans return and if so you can compare the different versions of the stats and plans to identify the culprit and correct it.

The queries from the two environments are run within a few minutes of each other, sometimes the Toad version first and sometimes the Access version. Each run uses the same, single bind value. Given that I can't see how the problem can be related to differences in statistics.

I'll check meta-link for odbc slow-down bugs.
