@Test public void testDecorrelateWithHavingAgg() throws Exception {
final String sql = "select ename\n"
+ "from sales.emp\n"
+ "group by ename, deptno\n"
+ "having max(sal) <= \n"
+ " (select max(sal) from sales.emp_b where "
+ "emp.deptno = emp_b.deptno group by ename)";
checkSubQuery(sql).withLateDecorrelation(true).check();
