             Summary: JDBC adapter wrongly pushes ORDER BY into sub-query
                 Key: CALCITE-3751
                 URL: https://issues.apache.org/jira/browse/CALCITE-3751
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde


JDBC adapter wrongly pushes ORDER BY into sub-query. When I run
{code}select deptno, job, sum(sal)
from scott.emp
group by deptno, job
order by 1,2;
{code}
against the hsqldb database via the JDBC adapter I get the error
{noformat}Error: Error while executing SQL "select deptno, job, sum(sal) from scott.emp group by deptno, job order by 1,2": While executing SQL [SELECT "DEPTNO", "JOB", SUM("SAL")
FROM (SELECT "JOB", "DEPTNO", SUM("SAL")
FROM "SCOTT"."EMP"
GROUP BY "JOB", "DEPTNO"
ORDER BY "DEPTNO" NULLS LAST, "JOB" NULLS LAST) AS "t0"] on JDBC sub-schema (state=,code=0)
{noformat}
Note that ORDER BY is inside a sub-query, which I presume is invalid SQL for hsqldb (and most other DBs).
