Wenchen Fan commented on SPARK-31761:
-------------------------------------
I think this is a breaking change and we should fix it.
The `div` operator always returns long type, so this should not overflow. The
`IntegralDivide` should cast input to long and divide.
> Sql Div operator can result in incorrect output for int_min
