使用NHibernate调用存储过程

Question

I can't get this stored procedure call to work. I keep getting a "Additional information: Parameter UserName does not exist as a named parameter in [LockUser]" message

using (var session = sm.OpenSession())         
{
    var query = session.CreateSQLQuery("LockUser")
    .SetString("UserName", User.UserName.ToString());                  
} 

mapping

<?xml version="1.0" encoding="utf-8" ?>                                                        <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
namespace="Models.Mappings" assembly="Intranet">
<sql-query name="LockUser">
    <property name="UserName"/>
    exec LockUser :UserName
</sql-query>

can anyone point me in the right direction?

Answer 1

You are mixing two features.

17.2. Named SQL queries

small cited snippet:

<sql-query name="persons">
    <return alias="person" class="eg.Person"/>
    SELECT person.NAME AS {person.Name},
           person.AGE AS {person.Age},
           person.SEX AS {person.Sex}
    FROM PERSON person
    WHERE person.NAME LIKE :namePattern
</sql-query>

usage:

IList people = sess.GetNamedQuery("persons")
    .SetString("namePattern", namePattern)
    .SetMaxResults(50)
    .List();

So as we can see there must be call GetNamedQuery()

Or you can use

Chapter 17. Native SQL

small cited snippet:

sess.CreateSQLQuery("SELECT ID, NAME, BIRTHDATE, DOG_ID FROM CATS")
    .AddEntity(typeof(Cat));

Summary: for named queries, we have to use .GetNamedQuery() . We can also use .CreateSQLQuery() to build SQL ourselves. Check also this for working example: Nhibernate CreateSQLQuery Stored Procedure result to non mapped class
