How do I use LIKE with a named parameter in the NHibernate query language?

"select * from Product WHERE field1 LIKE @p1; @p1='blah%' "

great, exactly what I was looking for.
I'll try it out and you'll get the points afterwards.

hmmm, i have tried it now, but it doesn't work.
are you sure that your example is for the NHibernate query language? I'm not looking for an SQL way of doing it...

didn't find the solution for this, but gotta close the question...

<query name="SEARCH_BLA">
<![CDATA[
Product WHERE field1 LIKE :field1]]>>

</query>

dONOT USE ANY % FOR HQL .
HOPE THIS WILL SOLVE.

string queryString = "from Product product where product.field1 like :field1";

IQuery query = session.CreateQuery(queryString);
query.SetParameter("field1", "%" +field1+ "%");

IList<Product> products = query.List<Product>();
