Oracle Data ControlDescription
Determines whether the dynaset will be used for read-only operations.
Read/write at design time and run time.
oradata1.ReadOnly = [ True | False ]
By default, ReadOnly is False which means that an attempt will be made to create an updatable dynaset by
selecting ROWIDs from the database. If ReadOnly is set to True, a non-updatable dynaset is created (ROWIDs are not selected from the
database and cached) and operations will be somewhat faster.
If the SELECT statement contains a LONG or LONG RAW column, ROWIDs are needed
whether the dynaset will be updatable or not.
Changing this property does not take effect until a Refresh method is sent to the data control.
