> {{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:
> {noformat}
> org.apache.calcite.sql.validate.SqlValidatorException: Rolled up column
> 'SLACKINGMIN' is not allowed in SELECT
