Hi,
I'm using the Jdbc Adapter and the SCOTT schema (emp, dept and salgrade).
When i execute the following query (i know that the second join doesn't
make sense, but it's only to show the error):
> SELECT count(*) FROM (SELECT count(emp.empno) `Count Emp`, dept.dname
> `Department Name` FROM Calcite.emp emp JOIN Calcite.dept dept ON emp.deptno
> = dept.deptno JOIN Calcite.salgrade salgrade ON emp.comm = salgrade.hisal
> WHERE dept.dname LIKE '%O%' GROUP BY emp.deptno, dept.dname)
a CastException is thrown:
"org.apache.calcite.adapter.jdbc.JdbcRules$JdbcJoin cannot be cast to
org.apache.calcite.adapter.enumerable.EnumerableRel".
generates a plan:
> [TABLE, #ID {PLAN=EnumerableAggregate(group=[{}], EXPR$0=[COUNT()])
> EnumerableAggregate(group=[{2, 4}])
> JdbcJoin(condition=[=($1, $0)], joinType=[inner])
> JdbcProject(hisal=[$2])
> JdbcTableScan(table=[[Calcite, salgrade]])
> JdbcJoin(condition=[=($1, $2)], joinType=[inner])
> JdbcProject(comm=[$6], deptno=[$7])
> JdbcTableScan(table=[[Calcite, emp]])
> JdbcProject(deptno=[$0], dname=[$1])
> JdbcFilter(condition=[LIKE($1, '%O%')])
> JdbcTableScan(table=[[Calcite, dept]])
> , }]
Can i create an issue for this?
Best regards,
Miguel.
