How do you get a non-matching record?
SELECT B. Accountid FROM TableB AS B LEFT JOIN TableA AS A ON A.ID = B. Accountid WHERE A.ID IS NULL; LEFT JOIN means it takes all the rows from the first table – if there are no matches on the first join condition, the result table columns for table B will be null – that’s why it works.
How can I get non-matching records from two tables?
The second way to find non-matching records between tables is to use NOT in conjunction with the IN operator. The IN operator allows you to specify multiple values in a WHERE clause, much like a string of ORs chained together.

How to select rows with no matching entry?

How to get unmatched records from F1 and F2?
A simple JOIN UNPAIRED will give you matched as well unmatched records from both F1 and F2. You also don’t need to build the record once again when the indicator is ‘1’ as the data is already present in positions 1 thru 80. You can use IFOUTLEN=80, to make sure we got the right LRECL for output. REFORMAT FIELDS= (F1:1,80,F2:1,80,?)
