Hello + Type Massage Question
Hi All,
Finally have the opportunity to use Pig in my day job. Things are going
well; doing some pretty real stuff!
Quick type massage question, a minor issue really.
I have an expression that looks like this:
(TOTAL_PYMT_POSI_AMT EQ '' ? 0 : TOTAL_PYMT_POSI_AMT) -
(TOTAL_PYMT_NEG_AMT EQ '' ? 0 : TOTAL_PYMT_NEG_AMT) as TOTAL_PYMT_AMT
Pig seems to implicitly cast the types to float/double so the resulting
data field - when dumped - has a decimal, which I don't want.
Is there a way for me to cast the result of the calculation to an
integer, which is what I *do* want?
I noticed the syntax TOTAL_PYMT_AMT:int somewhere but that doesn't seem
to work...
Thanks in advance,
PaulO.

Try the types branch it has full support for types and explicit type
casting.
