Howto implement SQL EXIST subquery with EntityConditions

At the moment we remove some entities using a hand-crafted SQL statement
which is quite ugly. Unfortunately we don't know any other solution.

Here is the code snippet so far:


String sql =
  "EXISTS (SELECT p.product_id"
+ "          FROM prodcut p"
+ "         WHERE p.product_id = product_category_member.product_id"
+ "           AND p.primary_product_category_id <>
product_category_member.product_category_id"
+ "           AND p.facility_id = '" + facilityId + "'"
+ ")";

EntityCondition condition = EntityCondition.makeConditionWhere(sql);
delegator.removeByCondition("ProductCategoryMember", condition);


How is it possible to refactor this using EntityConditions?

Regards,
René
