I need an outer join

[wgma]

I have two queries that return similar data except one of the queries returns data over an expanded date range.

Q1 returns data from 2004 to 2007
Q2 returns data from 2004 to 2008

I need to be able to only return those records from Q2 that do not exist in Q1.

How can I do that?

Thanks.

Using a left outer join

SELECT Q2.*
FROM Q2 LEFT JOIN Q1 ON Q2.ID=Q1.ID
WHERE Q1.ID IS NULL

For "ID" use whatever common field(s) link your table

That did it. Thanks.
