QUERY_PLAN_TEXT_CACHING Option

ON, OFF

OFF

Option can be set at the database (PUBLIC) or user level. At the database level, the value becomes the default for any new user, but has no impact on existing users. At the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.

Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.

IQ query plans vary in size and can become very large for complex queries. Caching plans for display on the Interactive SQL client can have high resource requirements. The QUERY_PLAN_TEXT_CACHING option gives users a mechanism to control resources for caching plans. With this option turned OFF (the default), the query plan is not cached for that user connection.
