REASSIGN OWNED
Function
REASSIGN OWNED changes the owner of a database.
REASSIGN OWNED requires that the system change owners of all the database objects owned by old_role to new_role.
Precautions
- REASSIGN OWNED is often executed before deleting a rule. Because objects in other databases are not affected, you usually need to run this command in each database that contains the objects owned by the role to be deleted.
- You must have the permissions on the original and target roles to execute it.
- The resource management module does not monitor the data switch of the syntax. You need to call select gs_wlm_readjust_user_space(0) to manually calibrate the monitoring data.
Syntax
