OUTER JOIN

This is my code:

            Query query2 = new Query
            {
                EntityType = typeof(LQ_StudentApply),
                QueryExpression = Entity.Attribute<LQ_StudentApply>("LQ_SchoolId") == SchoolId
            };
            query2.Mappings.Add(typeof(LQ_StudentApply), "t0");
            query2.Mappings.Add(typeof(LQ_Member), "t1");
            query2.Mappings.Add(typeof(LQ_Member), "t2");
            query2.Join = Join.Outer(typeof(LQ_StudentApply), typeof(LQ_Member),"t0","t1","Operator", "Id");
            query2.Join.And(Join.Outer(typeof(LQ_StudentApply), typeof(LQ_Member), "t0", "t2", "LQ_MemberId", "Id"));
            var rst = dbPlatform.Find(query2, query2.Mappings);
            var r2 = rst.GetCollection<LQ_StudentApply>();

when I run the code,I get an SQL exception saying

SqlException: The multi-part identifier "t2.Id" could not be bound.........The multi-part identifier "t2.DeletedOn" could not be bound. etc....

It has bothering me for a long time ^-^.

Pls help me .

Are you able to send through a small repro project so we can understand the model etc a bit better? Its a bit hard to say what the problem might be given just the query.
