frameworks - Convert SQL statement with "having" clause to Linq -


i've been converting manual sql repository uses sqlcommand , sqlconnection use ef4 , far apart have got stuck trying right sql statement linq.

i've been trying time , i'm not getting right results when run query ( sql coming ef4 crazy ).

here query:

select * [accounts] [a] inner join (  select [a].[id]  [accounts] [a]  inner join [people] [b] on [a].[personid] = [b].[id]  inner join [companies] [d] on [b].[companyid] = [d].[id]  left outer join [accountorganizationalunit] [c] on [a].[id] = [c].[accountid]  left outer join [organizationalunits] [e] on [c].[organizationalunitid] = [e].[id]  [d].[groupid] = @groupid  group [a].[id]  having sum(case [e].[companyid] when @companyid 1 else 0 end) = 0 ) [t2] on [a].[id] = [t2].[id]

the "having" clause causing trouble cant seem ef4 create similiar sql. @groupid guid , companyid int.

thanks help/guidance how can write in linq! if need more info let me know.

cheers,

richard.
