Functions SQLDataSources*/SQLDrivers* are local to this DLL and not forwards onto the driver DLL.
Hense the Environment handle being passed as the first parameter.
Said functions need to return SQL_NO_DATA to state we have no data instead of an SQL_ERROR.

Allows it to run now, more work will be required to make it fully functional.
