For simplicity, lets assume the following:
Table 1 has fields A and B
Table 1 has some records
I have a script that adds records to Table 1
Here's what I want:
If the script enters a new record that matches both field A and field B of an existing record, I don't want the new record to be added.
What do I include in my script? Or is there another approach?
Thanks for any help,
