JingsongLi commented on issue #10619: [FLINK-15175]Fix CTES not supported in SQL CLI URL: https://github.com/apache/flink/pull/10619#issuecomment-566926207 > We should be careful with introducing new SQL syntax. Is this official SQL standard? Are other vendors (like Oracle, Hive, Postgres) supporting this as well? It would be nice if you can do some research here. +1. Calcite support this syntax. If not so official, I think we can wait the refactor of SQL-CLI, then using calcite to parse query in SQL-CLI, and this syntax will be supported.
