Unmatching records without modifying the loading script
I have 2 tables joined with a field called ID, I have e.g. a table A and table B as shown below. How can I list in a straight table the non-matching records, i.e. records with ID 5, 6 and 7 from table B?
Ideally, I don't want to make the unmacthing/changes to my loading scripts. Is there any kind of expression to make this listing inside a table object?
