Koji Kawamura 13b59b5621 NIFI-3958: Decimal logical type with undefined precision and scale.
- Oracle NUMBER can return 0 precision and -127 or 0 scale with variable scale NUMBER such as ROWNUM or function result
- Added 'Default Decimal Precision' and 'Default Decimal Scale' property to ExecuteSQL and QueryDatabaseTable to apply default precision and scale if those are unknown
- Coerce BigDecimal scale to field schema logical type, so that BigDecimals having different scale can be written
