public List<Orders> GetOrders(String email,String icode,String c1, String c2, String c3)
{
PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(Orders.class);
query.setFilter("Email == pEmail && ItemCode == pItemCode && Col1 == pCol1 && Col2 == pCol2 && Col3 == pCol3");
query.declareParameters("String pEmail, String pItemCode, String pCol1, String pCol2, String pCol3");
query.setRange(0,50);
query.setOrdering("Id desc");
return (List<Orders>) query.execute(email,icode,c1,c2,c3);
}
The above code gives error because maximum 3 arguments can be passed to execute method. Is there a way to get data from google datastore using more than 3 column filter?
