By default, the Integration Service passes data to the Custom transformation procedure one row at a time. However, use the INFA_CTSetDataAccessMode() function to change the data access mode to array-based. When you set the data access mode to array-based, the Integration Service passes multiple rows to the procedure as a block in an array.

When you set the data access mode to array-based, you must use the array-based versions of the data handling functions and row strategy functions. When you use a row-based data handling or row strategy function and you switch to array-based mode, you will get unexpected results. For example, the DLL or shared library might crash.

You can only use this function in the procedure initialization function.

If you do not use this function in the procedure code, the data access mode is row-based. However, when you want the data access mode to be row-based, include this function and set the access mode to row-based.

Use the following syntax:

The following table describes the arguments for this function:
