wtf created DRILL-7931:
--------------------------

             Summary: Rowtype mismatch
                 Key: DRILL-7931
                 URL: https://issues.apache.org/jira/browse/DRILL-7931
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.18.0
            Reporter: wtf
            Assignee: wtf


 It's work correct for example in case when there is only one aggregation:

{{select col1, stddev(col2) FROM}}
{{    (values ('UA', 3), ('USA', 2), ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 LIMIT 6;}}

{{}}Or when it's after other aggregations:
{{select col1, SUM(col2), stddev(col2) FROM}}
{{    (values ('UA', 3), ('USA', 2), ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 LIMIT 6;}}

{{}}But when we try to put it before an aggregation, like SUM:
{{}}

{{}}{{select col1, stddev(col2), SUM(col2) FROM}}
{{    (values ('UA', 3), ('USA', 2), ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 LIMIT 6;}}{{}}

{{}}It's failed with error:
{{SYSTEM ERROR: AssertionError: Type mismatch:}}
{{rowtype of new rel:}}
{{RecordType(CHAR(3) NOT NULL col1, BIGINT $f1, BIGINT $f2, BIGINT NOT NULL $f3, BIGINT $f4) NOT NULL}}
{{rowtype of set:}}
{{RecordType(CHAR(3) NOT NULL col1, BIGINT $f1, BIGINT $f2, BIGINT NOT NULL $f3, BIGINT NOT NULL $f4) NOT NULL}}

{{}}Same for {{stddev_samp}}
