Oracle ODBC connection fails ([HY004] [Oracle][ODBC]Invalid SQL data type )

Hi there,

I am trying to ODBC connect to an Oracle database, semi-successfully that is.. The connect "as-is" works. It is only when I try to fetch a table that I get this error (DataSource.Error: ODBC: ERROR [HY004] [Oracle][ODBC]Invalid SQL data type <-25>

)

I googled and found this on an IBM help page: 

Cause: "ODBC libraries for Oracle do not support the SQL_C_SBIGINT ODBC type, which corresponds to the int64 SPL type."

Solution: "There is no workaround. If you use an Oracle database, do not use the SPL int64 type in your applications."

How can I change _not_ to use SPL int64 data type? Or is there another way around this?
