Hiroki Tateno updated OPENJPA-681:
----------------------------------

    Attachment: OPENJPA-681_1_1_x.patch

Hi,

I backported it to 1.1.x branch.
It works fine for my failure and I verified all tests were passed.
Would greatly appreciated if you merge this into 1.1.x.

Thanks,
Hiroki

> This is another kind of subquery that is not handled correctly in resolving table aliases,
the failed JPQL:
>         "select o1.oid, c.name from Order o1, Customer c where o1.amount = " +
>             " any(select o2.amount from in(c.orders) o2)",
> The incorrect SQL contains  t4.name where t4  is not defined in FROM clause:
> SELECT t0.oid, t4.name FROM Order t0 JOIN Customer t1 ON (1 = 1) WHERE (t0.amount = ANY
(SELECT t3.amount FROM Customer t1, Order t2, Order t3 WHERE (t2.oid = t3.oid) AND t1.countryCode
= t2.CUSTOMER_COUNTRYCODE AND t1.id = t2.CUSTOMER_ID )) 
> The correct SQL should be:
> SELECT t0.oid, t1.name FROM Order t0 JOIN Customer t1 ON (1 = 1) WHERE (t0.amount = ANY
(SELECT t3.amount FROM Order t2, Order t3 WHERE (t2.oid = t3.oid) AND t1.countryCode = t2.CUSTOMER_COUNTRYCODE
AND t1.id = t2.CUSTOMER_ID ))
