i am trying to write a LINQ query but somehow it is not working, here is the query
var Table3Qry =
from LoginTable in db.Logins
from ServerTable in LoginTable.Servers.Where(x => x.ServerID == id)
select new { LoginTable.passwd, LoginTable.LoginID };
Table Structures are
Login
- Passwd
- Userid
- Loginid
Server
- Serverid
- Servername
ServerLogins
- Serverid
- Loginid
I want to find all the Password
s in Login
table to a specific ServerID
(named id
in the query).
Filter servers by id, then select all passwords from each server logins:
var passwords =
db.Servers.Where(s => s.ServerID == id)
.SelectMany(s => s.Logins.Select(l => new { l.Passwd, l.LoginId }));
Query syntax:
var passwords = from s in db.Servers
where s.ServerID == id
from l in s.Logins
select new { l.Passwd, l.LoginId };
If you are starting from Logins table:
var passwords = from l in db.Logins
where l.Servers.Any(s => s.ServerID == id)
select new { l.Passwd, l.LoginId };
