FLUSH PACKAGE CACHE statement

The FLUSH PACKAGE CACHE statement invalidates all cached dynamic SQL statements in the package cache. This invalidation causes the next request for any SQL statement that matches an invalidated cached dynamic SQL statement to be compiled instead of reused from the package cache.

Invocation

This statement can be embedded in an application program or issued by using dynamic SQL statements. It is an executable statement that can be dynamically prepared.

Authorization

The privileges that are held by the authorization ID of the statement must include SQLADM or DBADM authority.

Syntax


>>-FLUSH PACKAGE CACHE--DYNAMIC--------------------------------><

Notes

This statement affects all cached dynamic SQL entries in the package cache on all active database partitions.
As cached dynamic SQL statements are invalidated, the package cache memory that is used for the cached entry is freed if the entry is not in use when the FLUSH PACKAGE CACHE statement runs.
Any cached dynamic SQL statement currently in use is allowed to continue to exist in the package cache until it is no longer needed by the current user. The next new user of the same statement will force an implicit prepare of the statement, and the new user will run the new version of the cached dynamic SQL statement.
