Hi,


definitively.



oh, you probably also want to know how?


SELECT a.id, a.companyName, a.attemployee - b.attemployee
FROM table1 As a INNER JOIN table2 as b
ON a.id=b.id AND a.companyName=b.companyName



Note that if id is a primary key, you can simplify to:

SELECT a.id, a.companyName, a.attemployee - b.attemployee
FROM table1 As a INNER JOIN table2 as b
ON a.id=b.id



That assumes the id is present in both table. If it is present just in
table1:

SELECT a.id, a.companyName, a.attemployee - Nz( b.attemployee, 0)
FROM table1 As a LEFT JOIN table2 as b
ON a.id=b.id

is preferable.... it just subtract 0 when the id is not present in table2,
still showing the original (table1) value, if you prefer.
