Specifying Fragments
If you specify no fragment, the privileges are revoked for all fragments of table. You can specify one fragment or a comma-separated list of fragments enclosed between parentheses that immediately follow the ON table specification.
Each fragment must be referenced by its name. If you did not declare an explicit identifier when you created the fragment, its name defaults to the name of the dbspace in which it resides.
After a dbspace is renamed successfully by the onspaces utility, only the new name is valid. HCL OneDB™ automatically updates existing fragmentation strategies in the system catalog to substitute the new dbspace name, but you must specify the new name in REVOKE FRAGMENT statement to reference a fragment whose default name is the name of a renamed dbspace.
