You can take advantage of DataDirect Bulk Load either through the Driver setup dialog or programmatically.
Applications that are already coded to use parameter array batch functionality can leverage DataDirect Bulk Load features through the Enable Bulk Load connection option on the Bulk tab of the Driver setup dialog. Enabling this option automatically converts the parameter array batch operation to use the database bulk load protocol without any code changes to your application.
If you are not using parameter array batch functionality, the bulk operation buttons Export Table and Load Table on the Bulk tab of the driver Setup dialog also allow you to use bulk load functionality without any code changes. See "Bulk tab" for a description of the Bulk tab.
If you want to integrate bulk load functionality seamlessly into your application, you can include code to use the bulk load functions exposed by the driver.
For your applications to use DataDirect Bulk Load functionality, they must obtain driver connection handles and function pointers, as follows:
1. Use SQLGetInfo with the parameter SQL_DRIVER_HDBC to obtain the driver’s connection handle from the Driver Manager.
2. Use SQLGetInfo with the parameter SQL_DRIVER_HLIB to obtain the driver’s shared library or DLL handle from the Driver Manager.
3. Obtain function pointers to the bulk load functions using the function name resolution method specific to your operating system. The bulk.c example program shipped with the drivers contains the function resolveName that illustrates how to obtain function pointers to the bulk load functions.
