Displays detailed information about each dbfile in a dbspace.
sp_iqfile [ dbspace-name ]
DBA authority required. Users without DBA authority must be granted EXECUTE permission to run the stored procedure.
sp_iqfile displays the usage, properties, and types of data in each dbfile in a dbspace. You can use this information to determine whether data must be moved, and for data that has been moved, whether the old versions have been deallocated.
sp_iqfile displays the following information:
