----------------------------------

             Summary: Remove predicate restrictions on TableFunction left outer join
                 Key: FLINK-7865
                 URL: https://issues.apache.org/jira/browse/FLINK-7865
             Project: Flink
          Issue Type: Sub-task
          Components: Table API & SQL
            Reporter: Xingcan Cui


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, remove validation tests, update 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.
