[jira] [Updated] (CALCITE-2986) Wrong results with =ANY subquery

     [ https://issues.apache.org/jira/browse/CALCITE-2986?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vineet Garg updated CALCITE-2986:
---------------------------------
    Description: 
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
