[jira] [Created] (CALCITE-1931) rank/ntile/etc. functions should not always return INTEGER

MinJi Kim created CALCITE-1931:
----------------------------------

             Summary: rank/ntile/etc. functions should not always return INTEGER
                 Key: CALCITE-1931
                 URL: https://issues.apache.org/jira/browse/CALCITE-1931
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: MinJi Kim
            Assignee: Julian Hyde


For example, rank() and percent_rank() both return INTEGER.  For rank(), it would be better to return BIGINT; for percent_rank(), we should actually return double or float since it is a percent value.  There are other rank functions that should return floating number instead of integer.
