Question

I’m trying to build a linq query for the following sql query :

SELECT *
FROM [QryFiles2]
WHERE (left(Demande,6) IN (select NoBVR from tblRequest))

Knowing that QryFiles2 is an entity and tblRequest too I’ve come to something like that :

from f in db.QryFiles2
where  f.Demande.Substring(0,6) /* in (select NoBVR from tblRequest) */
select f

The thing is I don’t know how I could express the in sql statement using linq. Do you know how I could do that without using raw sql queries ?

Nb : I’ve tried to use the .contains method but I couldn’t work it out with the computed substring.

Answer 1

Finally I’ve done this using a join statement like that :

from f in db.QryFiles2
join r in db.tblRequest on f.Demande.Substring(0,6) equals r.NoBVR

Super clean super fast no need for subqueries should have thought about that before 🙂
