    Description

      The the conversion fails for values > 0x80000000000000(or 36028797018963968 decimal)
      SQLFetch() returns error in such case. SQLGetData() does not, but truncates the value to 0x80000000000000(or 36028797018963968). This value must be platform dependent though - the max int64 translated to double w/out truncation.
      3.2 driver does not have that problem.
