Well, if the type has no precision, what do you suggest? Â Move the fix
back to CastIntDecimal.java (calculate the precision based on the value), as I
originally had it, but Jinfeng insisted was incorrect?
You two fellows, Jinfeng and Aman, can decide among yourselves. Â Let me
know when you're finished duking it out. Â If there are any survivors, we can
discuss on the hangout tomorrow.

Did you consider checking whether the type has a precision or not using
getMajorType().hasPrecision() ? That way, you would only call getPrecision() if
it returned True and otherwise set the precision for INT, BIGINT. â
