Vineet Garg updated CALCITE-2986:
---------------------------------
Labels: sub-query (was: )
> Wrong results with =ANY subquery
> --------------------------------
>
> Key: CALCITE-2986
> URL: https://issues.apache.org/jira/browse/CALCITE-2986
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Vineet Garg
> Assignee: Vineet Garg
> Priority: Major
> Labels: sub-query
>
> ANY/SOME subqueries are rewritten using MAX/MIN and cross-join. This is wrong
> transformation for {{=ANY}} and {{<>ANY}} (and therefore {{=ALL}} and
> {{<>ALL}}).
> Query
> {code:sql}
> select * from "scott".emp where empno = any (select empno from "scott".emp);
> {code}
> Expected output for above query is all rows from {{scott.emp}} but actual is
> only one row
> Test case: e.g.
> https://github.com/apache/calcite/compare/master...vineetgarg02:CALCITE-2986
