Question

Using sql server 2008, I need a query to display the following results

 User_Name        Group_Name          Checked
 user1              Lead                 0
 user1              Admin                1
 user1              Supervisor           0
 user1              Monitor              0
 user2              Lead                 0
 user2              Admin                0
 user2              Supervisor           1
 user2              Monitor              1

I have 4 groups (Lead, Admin, Supervisor, monitor) and the linking table is User Group. How do I get all groups displayed for each user (like above)? if group is checked for a user it appears in the User Group, not in the table if unchecked.

The tables:

User:

User_ID int
User_Name nvarchar
Email nvarchar

Group:

Group_ID int
Group_Name nvarchar

User Group:

User_ID int, 
Group_ID int

Answer 1

try this:

select User.User_Name, Group.Group_Name,
 case when UserGroup.User_ID is null then 0 else 1 end as Checked
from User cross join Group
 left join UserGroup on User.User_ID = UserGroup.User_ID
   and Group.Group_ID = UserGroup.Group_ID
