[ @pktable_owner = 'The database user who created the table.' ] ,
[ @pktable_qualifier = 'Database name.' ] ,
[ @fktable_name = 'Table name.' ] ,
[ @fktable_owner = 'The database user who created the table.' ] ,
[ @fktable_qualifier = 'Database name.' ] ;

@pktable_owner = 'dbo',
@pktable_qualifier = 'model',
