Returns a dynaset defined by the data control's Connect, DatabaseName, and RecordSource properties. Not available at design time and read and write at run time.
The properties and methods of this dynaset are the same as those of any other dynaset object. The Recordset property of the Oracle Data Control (.OCX) can be set to external dynaset, or the Recordset property of the other data control. After the setting, Oracle Data control Database, session, and options properties now set to the corresponding properties of the external dynaset. Oracle data control shares the advisories of the external dynaset. This is very useful when attaching dynaset returned from the PL/SQL cursor by CreatePlsqlDynaset Method.
This example demonstrates setting Recordset property to external dynaset created by CreatePlsqlDynaset method. This example returns a PL/SQL cursor as a external dynaset for the different values of DEPTNO parameter. Make sure that corresponding stored procedure (found in EMPCUR.SQL) is available in the Oracle Database. Copy this code into the definition section of a form containing the Oracle Data Control named oradata1. Then, press F5.
