Subject [jira] [Created] (CALCITE-3061) Query with WITH clause fails when alias is the same as the table with rolled up column
Date Fri, 10 May 2019 16:16:00 GMT
Volodymyr Vysotskyi created CALCITE-3061:
--------------------------------------------

             Summary: Query with WITH clause fails when alias is the same as the table with
rolled up column
                 Key: CALCITE-3061
                 URL: https://issues.apache.org/jira/browse/CALCITE-3061
             Project: Calcite
          Issue Type: Bug
            Reporter: Volodymyr Vysotskyi
            Assignee: Volodymyr Vysotskyi
             Fix For: 1.20.0


{{SqlValidatorImpl}} incorrectly resolves aliases for CTE when checking rolled up columns
when a table with the same name is present.

It may be observed with the following case: we have table {{emp_r}} which contains rolled
up column {{slackingmin}}. The following query:
{code:sql}
with emp_r as (select 1 as slackingmin) select slackingmin from emp_r
{code}
should pass since it uses CTE, not table.
 Error for this case:
