Parameterizing a HQL IN clause using HqlBasedQuery?

Question

How do you pass a list of things for the \'in\' clause in Nhibernate HQL?

e.g.

// data input from the user interface, not known at compile time
object[]          


        

Answer 1

Use SetParameterList().

Code snippet from billsternberger.net:

ArrayList stateslist = new ArrayList();
stateslist.Add("TX");
stateslist.Add("VA");

string hql = String.Format("FROM Contact c where State in (:states)");
SimpleQuery<Contact> q = new SimpleQuery<Contact>(hql);
q.SetParameterList("states", stateslist);

Contact[] result = q.Execute();
