Subject [jira] [Created] (PHOENIX-2536) Return of SUM function does not have the correct data type
Date Thu, 17 Dec 2015 23:06:46 GMT
Kevin Liew created PHOENIX-2536:
-----------------------------------

             Summary: Return of SUM function does 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


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.
