Hi Tom,
My understanding of using SQL Profiles has always been that they would prevent (frequent) changes in access paths of SQL statement.
This morning I noticed that, despite the fact that an SQL profile was connected to a statement and statiastics are gathered on a regular basis, the database all of a sudden decided to use a different access path which was terribly worse than what I expected.
My questions to you:
1. Is my general understanding of the use of SQL profiles incorrect?
2. If so, why should they be used at all?
Regards, Jaco de Graaf
