sam lin commented on FLINK-17852:
---------------------------------
[~f.pompermaier]: Nope, this is for SELECT statement, the issue you pointed is
CREATE statement. The name after WITH acts like a variable stores the resulting
values of sub-sql.
> FlinkSQL support WITH clause in query statement

> Key: FLINK-17852
> URL: https://issues.apache.org/jira/browse/FLINK-17852
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API
> Reporter: sam lin
> Priority: Major
>
> Many modern SQL language support WITH clause in query statement. e.g.
> ```
> WITH myName AS (
> select * from table where ...
> )
> select column1 from myName
> ```
> e.g. In BeamSQL supports this:
> [https://beam.apache.org/documentation/dsls/sql/calcite/query-syntax/]
> query_statement: [ WITH with_query_name AS ( query_expr ) [, ...] ]
> query_expr.
> In presto, supports this as well:
> [https://prestodb.io/docs/current/sql/select.html#with-clause]
