Knut Anders Hatlen commented on DERBY-5546:
-------------------------------------------
I guess we could see what happens when updateDouble() is used on an INTEGER
column and use that for guidance. For example, what happens when trying to
update to:
* 1.1 (does it fail or set the value to 1?
* 0.1 - analogous to the underflow case
And also, what happens with updateLong(1, Long.MAX_VALUE) on a REAL column? (I
think it loses precision, but does it fail?)
> ResultSet#updateBigDecimal on a REAL column does not do underflow checking
