Description

Added this test case in SqlToRelConverterTest:

@Test void testGroupByCoalesceIn() {
    final String sql = "select case when coalesce(ename, 'a') in ('1', '2')\n" +
        "then 'CKA' else 'QT' END, count(distinct deptno) from emp\n" +
        "group by case when coalesce(ename, 'a') in ('1', '2') then 'CKA' else 'QT' END";
    sql(sql).ok();
  }
