OLE DB Programmer's Reference |
This optional interface encapsulates command optimization, a separation of compile time and run time, as found in traditional relational database systems. The result of this optimization is a command execution plan.
If the provider supports command preparation, by supporting this interface, commands must be in a prepared state prior to calling the following methods:
Method | Description |
---|---|
Prepare | Validates and optimizes the current command. |
Unprepare | Discards the current command execution plan. |
