Solution 1

If you are using SQL 2005+ then use the following which will give you all the rows which are different:

SQL

SELECT * FROM (SELECT * FROM table1
               EXCEPT
               SELECT * FROM table2) a
UNION ALL
SELECT * FROM (SELECT * FROM table2
               EXCEPT
               SELECT * FROM table1) b

You can specify a column and check that by replacing the * with a column name.
