Date Tue, 05 Apr 2011 23:24:06 GMT


Carl Steinbach updated HIVE-436:

    Component/s: UDF

> MIN and MAX should inherit type

> MIN and MAX functions currently return the DOUBLE type...but really, they should return
the same type as the column they operate on.
> In some cases like SUM, it's possible that the result would overflow making DOUBLE more
useful as it can drop digits and swap to scientific notation, but MIN and MAX by definition
cannot have this problem because the answers are always represented in the column they are
run across.
> Easy workaround: CAST all of my MINs and MAXes. It's just a wish.
