-----------------------------------

             Summary: window function does not support multiple partition columns
                 Key: CALCITE-1540
                 URL: https://issues.apache.org/jira/browse/CALCITE-1540
             Project: Calcite
          Issue Type: Bug
    Affects Versions: 1.10.0
            Reporter: hongbin ma
            Assignee: Julian Hyde


When I add multiple partition columns to a window function:

{code:xml}

  @Test public void testSelect() throws SQLException {
    checkSql("model", "select NAME,DEPTNO,count(*) over (partition by NAME,DEPTNO) from EMPS");
  }

{code}

Following exception is thrown:

java.sql.SQLException: Error while executing SQL "select NAME,DEPTNO,count(*) over (partition by NAME,DEPTNO) from EMPS": Error while compiling generated Java code:

However the document from calcite.apache.org/docs/reference.html states multiple partition columns should be allowed:

{code}
windowSpec:
      [ windowName ]
      '('
      [ ORDER BY orderItem [, orderItem ]* ]
      [ PARTITION BY expression [, expression ]* ]
      [
          RANGE numericOrIntervalExpression { PRECEDING | FOLLOWING }
      |   ROWS numericExpression { PRECEDING | FOLLOWING }
      ]
      ')'

{code}

After searching it seems no one is reporting the same issue. I'm opening this JIAR as a placeholder, will try to fix this issue
