QUERY_PLAN_TEXT_ACCESS
Option
Enables or prevents users from accessing query plans from the Interactive SQL client or from using SQL functions to get plans.
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 SYSTEM OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.
When QUERY_PLAN_TEXT_ACCESS option is ON, users can view, save, and print query plans from the Interactive SQL client. When the option is OFF, query plans are not cached, and other query plan-related database options have no effect on the query plan that is shown from the Interactive SQL client. This error message appears:
No plan available. The database option QUERY_PLAN_TEXT_ACCESS is OFF.
