Making a query for a SQL Server database

I would like to make a query for my SQL Server database to specify that only unmatching records should be displayed from both tables. Can you help me in doing so?

Thanks. We'll let you know when a new response is added.

You could use a combination of UNION and EXCEPT to get the unmatching records.

Something like this:

<pre>(<query_table_1_>
EXCEPT
<query_table_2>)
UNION
(<query_table_2_>
EXCEPT
<query_table_1>)</pre>

Alternatively, you could use subqueries to achieve the same result:

<pre>select col_a from table_1
where col_a not in (select col_a from table_2)
UNION
select col_a from table_2
where col_a not in (select col_a from table_1)
</pre>

Hope this helps.
