I created an After Insert Trigger. Therefore after I update Table A with a new ID, it performs an insert on Table B. That great, however each new insert after the first one on Table A causes Table B to get inserted again. In other words, when I update Table A with record ID = 1, Table B gets updated with ID 1 (perfect). However, when I then update Table A with record ID = 2, Table B gets updated with ID 2 and another or second ID = 1. So now I have 3 records (2 ID = 1, and 1 ID = 2). And if I did an ID = 3 in Table A, Table B would now have (3 ID = 1, 2 ID = 2, and 1 ID = 3 or 6 records) and I want (1 ID =3, I ID =2, and I ID = 1 or 3 records). I only want a single insert for each record inserted.
