Updating all records based on "On Success" scripts

Updating all records based on "On Success" scripts

For our catalogue publishing Zoho Creator app, there is a code that runs On Success for both On Add and On Edit. The script concatenates several fields and pre-formatted info into one value. The problem is that I have added the code after the initial import of data. So with any new records or edits added/updated the information is generated correctly, but Is there any way of forcing the script to run on all of the records in the database so they are all updated at once?

Thanks for your help.
