> Reporter: Sergey Nuyanzin
> Assignee: Sergey Nuyanzin
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.41.0
>
>
> It looks like usage of {{SqlValidatorImpl#validate}} for queries with
> {{LATERAL}} leads to it's losing.
> an example
> {code:java}
> sql("select * from emp, lateral table(ramp(emp.deptno)), dept")
> .rewritesTo("SELECT *\n"
> + "FROM `EMP`,\n"
> + "LATERAL TABLE(RAMP(`EMP`.`DEPTNO`)),\n"
> + "`DEPT`");
> {code}
> this will fail since currently it rewrites it to
> {code:sql}
> SELECT *
> FROM `EMP`,
> TABLE(RAMP(`EMP`.`DEPTNO`)),
> `DEPT`
> {code}
