A pointer to an array of BYTE values. This array will store the data to be transferred from the data source to the recordset.
A pointer to an array of long integers. This array will store the length in bytes of each value in the array pointed to by prgByteVals. Note that the value SQL_NULL_DATA will be stored if the corresponding data item contains a Null value. For more details, see the ODBC API function SQLBindCol in the ODBC SDK Programmer's Reference.
The maximum allowed length of the values stored in the array pointed to by prgByteVals. To ensure that data will not be truncated, pass a value large enough to accommodate the largest data item you expect.
