I am updating a large group of records to have a new need from the previous year (in this case, a 2017 sponsorship). In order to do this, I am simply copying the last year's 2016 sponsorship records into a temporary_table and updating the fields to reflect the new year's values.
My question is this: When I copied the records into the temporary_table, the auto-increment ID's also copied over. I can't set this column to NULL, so when I insert these records into the live table, will the table recognize that there are duplicate ID's and increment the new ones? Is there another way to handle it?
Thank you!
