--------------------------------
Summary: Return of aggregation functions do not have the correct data type
(was: Return of SUM function does not have the correct data type)
> Return of aggregation functions do not have the correct data type
> -----------------------------------------------------------------
>
> Key: PHOENIX-2536
> URL: https://issues.apache.org/jira/browse/PHOENIX-2536
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.6.0
> Reporter: Kevin Liew
> Labels: function, phoenix
>
> ANSI SQL specifies that
> {quote}If SUM is specified and DT is exact numeric with scale
> S, then the data type of the result is exact numeric with
> implementation-defined precision and scale S.
> ...
> If DT is approximate numeric, then the data type of the
> result is approximate numeric with implementation-defined
> precision not less than the precision of DT.{quote}
> However, when summing integer types (first operand) with float or double
> (second operand), Phoenix returns the value with the same data type as the
> first operand.
