  SQL Server Tips by Gama and Naughter

Outer left

An outer left join returns not only the rows that meet the join conditions but also all the rows from the table on the left of the JOIN clause, even if they have no correspondent column from the table on the right. If there is no correspondence on the right table a NULL value(s) will be assigned.

Example: To display all publishers, even the ones with no titles in the title database. When the publisher has no title in the database, the returned title will be NULL.

SELECT dbo.publishers.pub_name, dbo.titles.title
FROM dbo.publishers LEFT OUTER JOIN
dbo.titles ON dbo.publishers.pub_id = dbo.titles.pub_id
