I try to give entity map on my entity app. But how can I do it? I try to make it like below:
var test = ( from k in Kartlar where k.Rehber.....
above codes k.(can not see Rehber or not working ) if you are correct , i can write k.Rehber.ID and others. i can not write:
from
k in
Kartlar
where
k.Rehber.ID = 123 //assuming that navigation property name is Rehbar and its primary key of Rehbar table is ID
&& k.Kampanya.ID = 345 //assuming that navigation property name is Kampanya and its primary //key of Kampanya table is ID
&& k.Birim.ID = 567 //assuming that navigation property name is Birim and its primary key of Birim table is ID
select
k

I have a table it includes 3 foreign key field like that:
My Table: Kartlar
- ID (Pkey)
- RehberID (Fkey)
- KampanyaID (Fkey)
- BrimID (Fkey)
- Name
- Detail
How can i write entity query with LINQ ?
select * from Kartlar where RehberID=123 and KampanyaID=345 and BrimID=567
BUT please be careful I can not see RehberID, KampanyaID, BrimID in entity they are foreign key. I should use entity key but how?
