I am writing a method for retrieving clients with sum of their orders (order.total
) higher and less than input values.
Criteria criteria = DetachedCriteria.forClass(Clients.class, "cl");
if (clOrdsTtlPrcFrom != -1 && clOrdsTtlPrcTo != -1) {
String sql = "select OwnerID from Orders group by OwnerID having sum(Total) >= :clOrdsTtlPrcFrom and sum(Total) <= :clOrdsTtlPrcTo";
SQLQuery query = sess.createSQLQuery(sql).addScalar("OwnerID", LongType.INSTANCE);
query.setParameter("clOrdsTtlPrcFrom", clOrdsTtlPrcFrom);
query.setParameter("clOrdsTtlPrcTo", clOrdsTtlPrcTo);
criteria.add(Restrictions.in("id", query.list()));
}
Criteria criteria2 = sess.createCriteria(Clients.class);
criteria2.add(Subqueries.propertyIn("id", criteria));
List<Clients> clients = (List<Clients>) criteria2.list();
All it's okay, but sometimes I am getting an error:
java.sql.SQLException: Prepared or callable statement has more than 2000 parameter markers.
How can I correct this method, or, maybe, convert it to a criteria style?
In the end, i solved this problem by this way, using sql restriction:
DetachedCriteria dtcrt = DetachedCriteria.forClass(Clients.class);
dtcrt.setProjection(Projections.distinct(Projections.id()));
if (clOrdsTtlPrcFrom != -1 && clOrdsTtlPrcTo != -1) {
dtcrt.add(Restrictions.sqlRestriction("OwnerID in(select OwnerID from Orders group by " +
"OwnerID having sum(Total) >= ? and sum(Total) <= ?)", new Integer[]{clOrdsTtlPrcFrom, clOrdsTtlPrcTo},
new Type[]{StandardBasicTypes.INTEGER, StandardBasicTypes.INTEGER}));
criteria.add(Subqueries.propertyIn("id", dtcrt));
}
