How do you “OR” criteria together when using a criteria query with hibernate?
Question
I'm trying to do a basic "OR" on three fields using a hibernate criteria query.
Example
class Whatever{
string name;
string address;
string phoneNumber;
}
I'd like to build a criteria query where my search string could match "name" or "address" or "phoneNumber".
Solution
You want to use Restrictions.disjuntion()
. Like so
session.createCriteria(Whatever.class)
.add(Restrictions.disjunction()
.add(Restrictions.eq("name", queryString))
.add(Restrictions.eq("address", queryString))
.add(Restrictions.eq("phoneNumber", queryString))
);
See the Hibernate doc here.
OTHER TIPS
Assuming you have a hibernate session to hand then something like the following should work:
Criteria c = session.createCriteria(Whatever.class);
Disjunction or = Restrictions.disjunction();
or.add(Restrictions.eq("name",searchString));
or.add(Restrictions.eq("address",searchString));
or.add(Restrictions.eq("phoneNumber",searchString));
c.add(or);
//Expression : (c1 AND c2) OR (c3)
Criteria criteria = session.createCriteria(Employee.class);
Criterion c1 = Restrictions.like("name", "%e%");
Criterion c2 = Restrictions.ge("salary", 10000.00);
Criterion c3 = Restrictions.like("name", "%YYY%");
Criterion c4 = Restrictions.or(Restrictions.and(c1, c2), c3);
criteria.add(c4);
//Same thing can be done for (c1 OR c2) AND c3, or any complex expression.
//Expression : (c1 AND c2) OR (c3)
Criteria criteria = session.createCriteria(Employee.class);
Criterion c1 = Restrictions.like("name", "%e%");
Criterion c2 = Restrictions.ge("salary", 10000.00);
Criterion c3 = Restrictions.like("name", "%YYY%");
Criterion c4 = Restrictions.or(Restrictions.and(c1, c2), c3);
criteria.add(c4);
//Same thing can be done for (c1 OR c2) AND c3, or any complex expression.
Just in case anyone should stumble upon this with the same question for NHibernate:
ICriteria c = session.CreateCriteria(typeof (Whatever))
.Add(Expression.Disjunction()
.Add(Expression.Eq("name", searchString))
.Add(Expression.Eq("address", searchString))
.Add(Expression.Eq("phoneNumber", searchString)));
The conditions can be applied using the or / and in different levels of the query using disjunction
Criteria query = getCriteria("ENTITY_NAME");
query.add(Restrictions.ne("column Name", current _value));
Disjunction disjunction = Restrictions.disjunction();
if (param_1 != null)
disjunction.add(Restrictions.or(Restrictions.eq("column Name", param1)));
if (param_2 != null)
disjunction.add(Restrictions.or(Restrictions.eq("column Name", param_2)));
if (param_3 != null)
disjunction.add(Restrictions.or(Restrictions.eq("column Name", param_3)));
if (param_4 != null && param_5 != null)
disjunction.add(Restrictions.or(Restrictions.and(Restrictions.eq("column Name", param_4 ), Restrictions.eq("column Name", param_5 ))));
if (disjunction.conditions() != null && disjunction.conditions().iterator().hasNext())
query.add(Restrictions.and(disjunction));
return query.list();
