Sergey Nuyanzin updated CALCITE-7217:
-------------------------------------
Description:
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}
