Database Privileges

When a database object is created, such as a schema, table, or view, ownership of that object is assigned to the user who created it. By default, only the object's owner, and users with superuser privileges such as database administrators, have privileges on a new object. Only these users (and other users whom they explicitly authorize) can grant object privileges to other users

Privileges are granted and revoked by GRANT and REVOKE statements, respectively. The privileges that can be granted on a given object are specific to its type. For example, table privileges include SELECT, INSERT, and UPDATE, while library and resource pool privileges have USAGE privileges only. For a summary of object privileges, see Database Object Privileges.

Because privileges on database objects can come from several different sources like explicit grants, roles, and inheritance, privileges can be difficult to monitor. Use the GET_PRIVILEGES_DESCRIPTION metafunction to check the current user's effective privileges across all sources on a specified database object.
