Why dont you update your data rather than insert?

Do you have a primary / unique key field?

I see you have at least 4 questions about checkin and checkout table. Is SQL that hard for you?

Solution 1

I see either a design flaw or incomplete information in this scenario. Anyway one solution could be

SQL

select A.checkin, B.checkout
FROM
(
select ROW_NUMBER() ID, checkin
FROM diff
where checkout is null
) A INNER JOIN 
(
select ROW_NUMBER() ID, checkout
from diff
where checkin is null
) B ON A.ID = B.ID

Change the ID name to any other name and this should work. Please debug, it should not be hard!

To get your desired results you should use the UPDATE query; it will update the values in the selected column. While INSERT query adds a new row in the table due to which you are unable to get the results as per your expectations.
