[ https://issues.apache.org/jira/browse/FLINK-7865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17213104#comment-17213104 ]

-----------------------------------
hi [~xccui], Thanks for the information. I will have a look.
> Remove predicate restrictions on TableFunction left outer join
> --------------------------------------------------------------
>
> Key: FLINK-7865
> URL: https://issues.apache.org/jira/browse/FLINK-7865
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API
> Reporter: Xingcan Cui
> Priority: Major
>
> To cover up the improper translation of lateral table left outer join (CALCITE-2004), we have temporarily forbidden the predicates (except {{true}} literal) in Table API (FLINK-7853) and SQL (FLINK-7854). Once the issue has been fixed in Calcite, we should remove the restrictions. The tasks may include removing Table API/SQL condition check, removing validation tests, enabling integration tests, updating the documents, etc.
> See [this thread on Calcite dev list|https://lists.apache.org/thread.html/16caeb8b1649c4da85f9915ea723c6c5b3ced0b96914cadc24ee4e15@%3Cdev.calcite.apache.org%3E] for more information.
