I have two tables. The first is a item "types" as below
...the second is a table of "details". Each row represents 1 item of the total number of that item type. Each row in the second table will have unique data, like an ID, a physical address and a QR code....
If I add a new row in to table 1, with a qty of 20 units (in the Qty column), how can i automatically add that many rows to the second table, and link them to the dislay type from the first table?
Thanks
