How do I 'subtract' sql tables?

Question

Its not really a subtraction I\'m looking for. And I know its not a union or intersection... I have been given a long and complex stored procedure that returns a table of

Answer 1

SELECT both.*
FROM both LEFT OTUER JOIN inactives USING (whatever_id)
WHERE inactives.whatever_id IS NULL;

or

SELECT * FROM both
EXCEPT
SELECT * FROM inactives;

Answer 2

SELECT * FROM Table1 
LEFT JOIN Table2 on Table1.id = Table2.id
WHERE Table2.id IS NULL

this should work on almost any database engine

Answer 3

In MS TSql, I think you want the EXCEPT keyword.

query1 EXCEPT query2

Which will return all rows found in the first query that are not also found in the second query.

Answer 4

You can just used the first sp that return the Active & Inactive and in WHERE cluse put condition for the document status =inactive, you wil get inactive document only.

Answer 5

Assuming there are unique IDs that correspond across the two tables:

select * from table_both b
where not exists (select * from table_active a where a.id = b.id)

Answer 6

I believe EXCEPT is what you are looking for. Syntax is similar to UNION or INTERSECT.
