c# - How to do a proper left join in Entity Framework -

-

this should simple problem solve, reason entity framework makes hard me. need simple left join...

i have 2 tables. example, user table:

user_id | name | fk_group_id

and group table

group_id | groupname

in raw sql:

select * users u left join groups g on u.fk_group_id = g.group_id groupname = 'my group'

super easy in sql. when search answers on how entity framework, there's 1 thing immidiately goes through mind... wtf...!?!? super large constructed, weird formatted "queries" performed , i'm confused need , not...

so i'm hoping me specific problem. how 1 rewrite above sql query in (linq?) entity framework.

currently have this:

var bla = (from m in myent.users           // join attempt..           join mp in myent.groups on m equals mp.group_id n           n.group_name == "something"           select m);

even if working, don't see how suppose make life easier.. oo

anyway, hope can me out :-)

umm, don't have explicitly orm. that's catch here, that's mapping's for.

you can go:

var blah = myent.users.where(user => user.group.name == "something");

or in alternate syntax

from usr in myent.users usr.group.name == "something" select usr`

if it's many-to-one relationship after mapping objects, every user entity have navigation property group, , every group have user collection. have filter results appropriately.
