> Now Calcite will throw an exception when we execute the SQL:

> deptno from scott.dept b){code}
> I will try to rewrite this SQL become:
> {code:java}
> SELECT *
> FROM "SCOTT"."BONUS"
> LEFT JOIN ("SCOTT"."EMP" INNER JOIN (SELECT "DEPTNO"
> FROM "SCOTT"."DEPT"
> GROUP BY "DEPTNO") AS "t" ON "EMP"."DEPTNO" = "t"."DEPTNO") ON TRUE{code}
> The SQL :
> {code:java}
> select * from scott.emp e left join scott.bonus b on e.deptno in (select
> deptno from scott.dept b) {code}
> I will try to rewrite this SQL become:
> {code:java}
> SELECT *
> FROM "SCOTT"."EMP"
> LEFT JOIN ("SCOTT"."BONUS" CROSS JOIN (SELECT "DEPTNO"
> FROM "SCOTT"."DEPT"
> GROUP BY "DEPTNO") AS "t") ON "EMP"."DEPTNO" = "t"."DEPTNO" {code}
