Release 10.1A: OpenEdge Data Management:
SQL Development

Enhancing performance with locking hints

A range of table-level locking hints can be specified using the SELECT, INSERT, UPDATE, and DELETE statements to direct the OpenEdge SQL Engine to the type of locks to be used. Table-level locking hints can be used when a finer control of the types of locks acquired on an object is required. These locking hints override the current transaction isolation level for the session.
