Question

i have this query

var resultado = from c in conn.carrera
                            join u in conn.usuario on c.idusuario equals u.idusuario
                            join t in conn.texto on c.idtexto equals t.idtexto
                            where c.estatus == 1
                            select c;

how do i get something as it:

select c.*,u.*,t.eltexto from carrera c
join usuario u on c.idusuario =u.idusuario
join texto t on c.idtexto = t.idtexto
where c.estatus = 1

you could see in the query i am select c.*, u.* and t.col1, then
how can i get it in EF? because my first query gets only carrera.* but i need more data.

thanks

You could easily return a new object consisting all the properties of the three joined tables:

var resultado = from c in conn.carrera
                            join u in conn.usuario on c.idusuario equals u.idusuario
                            join t in conn.texto on c.idtexto equals t.idtexto
                            where c.estatus == 1
                            select new
                            { 
                               c.prop_1, 
                               c.prop_n, 
                               u.prop_1, 
                               u.prop_n, 
                               t.prop_1, 
                               t.prop_n 
                            };
