[jira] [Updated] (CALCITE-1382) ClassCastException in JDBC Adapter
[ https://issues.apache.org/jira/browse/CALCITE-1382?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Julian Hyde updated CALCITE-1382:
---------------------------------
Description:
This query:
{code}
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)
{code}
generates a ClassCastException: "org.apache.calcite.adapter.jdbc.JdbcRules$JdbcJoin cannot be cast to org.apache.calcite.adapter.enumerable.EnumerableRel".
The plan is the following:
{code}
[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]])
, }]
{code}
was:
