So, here's an example, assuming we are comparing tables A and B, and the
primary key of both tables is ID:

SELECT MIN(TableName) as TableName, ID, COL1, COL2, COL3 ...
FROM
(
SELECT 'Table A' as TableName, A.ID, A.COL1, A.COL2, A.COL3, ...
FROM A
UNION ALL
SELECT 'Table B' as TableName, B.ID, B.COL1, B.COl2, B.COL3, ...
FROM B
) tmp
GROUP BY ID, COL1, COL2, COL3 ...
HAVING COUNT(*) = 1
ORDER BY ID

Subject: comparing two tables

select * from srv.masson.dbo.coding a left join masson.dbo.coding b

on a.articlekey = b.articlekey

and a.systemkey = b.systemkey

where b.articlekey is null



this should bring back everything that's isn't present in table b
shouldn't
it?
