SUMMARY
=======
This article explains how to create an outer join on a SQL Server table using
the Remote View Designer. An outer join is necessary if the View needs to
display not only matching rows between tables (rows with values in the specified
columns that satisfy the join condition), but also non- matching rows. An outer
join can only be performed if the backend DBMS supports it. This article uses
the pubs database in Microsoft SQL Server.
MORE INFORMATION
================
This query uses the Authors table and the Publishers table and shows not only
authors who have publishers in the same city, but also authors without
publishers in the same city.
1. Create a datasource to the pubs database on SQL Server.
2. Create a new remote View, and select your new datasource created in step 1.
3. Select the Authors table.
4. Click again, and select the Publishers table.
5. The join condition dialog appears showing:
Publishers.city - Authors.city
6. Change the join condition to Right Outer Join.
7. Select the following fields from the Authors table:
authors.au_fname
authors.au_lname
8. Select the following field from the Publishers table:
Publisher.pub_name
9. Run the query.
