Default C data types

You can specify the SQL_C_DEFAULT for different functions so that HCL Informix® ODBC Driver uses the C data type.

If you specify SQL_C_DEFAULT for the TargetType argument in SQLBindCol, the fCType argument in SQLGetData, or the ValueType argument in SQLBindParameter, HCL Informix ODBC Driver uses the C data type of the output or input buffer for the SQL data type of the column or parameter to which the buffer is bound.
