Abstract
An apparatus, system, and method are disclosed for efficiently supporting generic SQL data manipulation statements. The method includes determining whether an SQL statement includes extended indicator parameters such as DEFAULT and UNASSIGNED indicators. The method further includes delaying an authorization check for an operation for an SQL statement using extended indicators, and bypassing an SQL exception where an otherwise unauthorized operation involves an UNASSIGNED variable. The method further includes bypassing a database operation such as a referential integrity check where a data change would induce the database operation, but the data change involves an UNASSIGNED variable. The method further includes modifying the SQL statement when the SQL statement involves an UNASSIGNED variable in a predicate clause, allowing the SQL statement to properly execute.
