Volodymyr Tkach commented on CALCITE-2135:
------------------------------------------
Checked, it has succeeded. The structure of the query is the same, but fields
names differ a little, because it is from JdbcTest class:
{noformat}
@Test public void testOverWithoutGroupBy() {
CalciteAssert.hr()
.query("SELECT e.\"empid\", SUM( e.\"empid\") OVER (PARTITION BY e.\"deptno\"
ORDER BY MIN( e.\"salary\")) avg_col0, e.\"deptno\" FROM \"hr\".\"emps\" as e
GROUP BY e.\"empid\", e.\"salary\", e.\"deptno\" ")
.returnsUnordered(
"empid=100; AVG_COL0=250; deptno=10\n" +
"empid=110; AVG_COL0=360; deptno=10\n" +
"empid=150; AVG_COL0=150; deptno=10\n" +
"empid=200; AVG_COL0=200; deptno=20");
}
{noformat}
So, I'm guessing AggChecker's logic needs to be changed.

> Project: Calcite
> Issue Type: Bug
> Reporter: Volodymyr Tkach
> Assignee: Julian Hyde
> Priority: Major
>
> I wrote 2 tests with queries:
> 1. Inside SqlValidatorTest class:
> {noformat}
> @Test public void testAggregateInsideOverWithoutGroupByFails() {
> check("SELECT empno, SUM(empno) OVER (PARTITION BY deptno ORDER BY
> MIN(sal)) empno_sum, deptno FROM emp ");
> }
> {noformat}
> The test succeeds but hasn't, because `sal` field and others are not being
> grouped. Tested on postgress, mysql and hive dbs, all of them demand grouping.
> 2. Inside JdbcTest class, similar query:
> {noformat}
> @Test public void testOverWithoutGroupBy() {
> CalciteAssert.hr()
> .query("SELECT e.\"empid\", SUM( e.\"empid\") OVER (PARTITION
> BY e.\"deptno\" ORDER BY MIN( e.\"salary\")) avg_col0, e.\"deptno\" FROM
> \"hr\".\"emps\" as e")
> .returnsUnordered(
> "doesn't matter, execution doesn't reach here.");
> }
> {noformat}
> Results with error:
> {noformat}
> java.lang.RuntimeException: exception while executing [SELECT e."empid",
> SUM( e."empid") OVER (PARTITION BY e."deptno" ORDER BY MIN( e."salary"))
> avg_col0, e."deptno" FROM "hr"."emps" as e]
