Update the specified BLOB member attribute in the given named collection. If a collection does not exist with the specified name for the current user in the same session for the current Application ID, an application error is raised. If the member specified by sequence ID p_seq does not exist, an application error is raised. If the attribute number specified is invalid or outside the valid range (currently only 1 for BLOB), an error is raised.
