Storing the unique ID
Hi Guys,
I know we can utilise the autonumber as a unique identifier. i intend to use this, however, in my database i will be having records being appending back and from tables, am i able to store the autonumber as a static field constantly? i.e. here would be the design
ID (auto)
StaticID (stored auto number)
So whenever this is appended or moved across, the ID will always be noted when it will enter the primary master table?

almost like a master ticket reference. So I will be able to pull the entire audit history for a ID, no matter no how many time its auto number has changed hands?

Hi Manny,
Thank you for the forum question.
You will need in the "new" table (the table you want to append the data to) to have a column which store the auto number from the source table and a primary key column in which you have the new autonumber.
I have created a tiny database (see attachment)
Kind regards

Hi Manny,
I hope that you have got the attachment. Sometimes it takes few minutes to be visible. If you in the future cannot see an attachment wait few minutes and refresh your browser.
I hope, that the solution works for you.
Kind regards
