Notes:
- Precision and scale must be integer constants. Precision may be in the range from 1 to 63. Scale may be in the range from 0 to the precision.
- If using the decimal data type, the header file decimal.h must be included.
- If using sqlint32 or sqlint64, the header file sqlsystm.h must be included.
