[jira] [Updated] (DRILL-2011) View on top of a aggregation over a
subquery fails to plan
[ https://issues.apache.org/jira/browse/DRILL-2011?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jason Altekruse updated DRILL-2011:
-----------------------------------
Description:
This last query in this test will currently fail to plan, the exception is - SEVERE: org.eigenbase.util.EigenbaseContextException: At line 0, column 0: Table 'EXPR$0' not found
The anonymous sub-query in the view is not able to be resolved inside of calcite, simply giving an alias to the subquery fixes the planning issue. The query runs fine if not defined in a view.
{{
@Test
public void testAggOnSubquery() throws Exception {
test("use dfs.tmp");
test("create or replace view testAggOnSubquery_view as select n_nationkey, sum(n_regionkey) from (select n_nationkey,n_regionkey from cp.`tpch/nation.parquet`) GROUP BY n_nationkey");
test("select n_nationkey from testAggOnSubquery_view");
}
}}
This runs fine
{{
select n_nationkey from (select n_nationkey, sum(n_regionkey) from (select n_nationkey,n_regionkey from cp.`tpch/nation.parquet`) GROUP BY n_nationkey)
}}
