This document provides information on the following topics:
- To create SQL Profiles for queries using literals where different literal values are passed for every execution.
- Use this SQL Profile for every execution of this SQL whatever the literal is changed to.
Default behavior: By default, if a SQL Profile is created for a sql containing literal values, then the profile would be generated solely for the query with whatever literals were used while running the tuning advisor. If the same SQL was executed with only a change in literals, then that profile would not be used for this query since the changing literal would make the SQL deemed to be a new query. Since profiles are identified by the SQL that they are recorded against, the profile would not be used for this "new" SQL.
