Hi All,

Just having a problem running a simple native sql query.
I am using postgresql 7.3.6 and hibernate 2.1.4

When I use a HQL query it works fine.

Here is my mapping file.

Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 2.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

</hibernate-mapping>


Here is my java code:

Code:
String sql = "SELECT {m}.* FROM MSG_OUT {m}";
List msgout = session.createSQLQuery(sql, "m", MsgOut.class).list();
for (Iterator it = msgout.iterator(); it.hasNext();) {
     MsgOut msg = (MsgOut) it.next();
     System.out.println(msg + "\n");
}


Here is the exception I get:

Code:
