Hi all,

I have three tables :maingroup, subgroup and mobile. I want to display all mobiles from all subgroups that belong to a specific main group.
How can I make that, please?
Thanks

SQL

alter proc mobile_select
(@maingroupid int)
as
begin
select mobile
from tbl_mobile, tbl_maingroup, tbl_subgroup
where
tbl_maingroup.maingroupId=@maingroupid  and
tbl_maingroup.maingroupId=tbl_subgroup.maingroupId
end

Solution 1

You forgot to give condition for tbl_mobile.
Unless you specify that condition, it will return all data.

Solution 2

You have not placed any condition for the Mobile table. Update the where clause and it will work.
