This is quick fix just for script operator. Current implementation of PPD has some flaws and seemed not easy to resolve perfectly.

> I'm using a multi table insert like this:
> FROM <x>
> INSERT INTO TABLE t PARTITION (type='x')
> SELECT * WHERE type='x'
> INSERT INTO TABLE t PARTITION (type='y')
> SELECT * WHERE type='y';
> Now when <x> is the name of a table, everything works as expected.
> However if I use a subquery as <x>, the query runs but it inserts all results from the subquery into each partition, as if there were no "WHERE" clauses in the selects.
