An application developer recently installed Fix Pack 8 to their Fix Pack 5 IBM WebSphere Commerce Developer toolkit. When the developer was in the process of executing the updateDB steps, they experienced a power outage on their workstation several minutes after the scripts had been successfully running.
After rebooting their system, the developer continued their upgrade where they left off on the updateDB steps, but the script failed immediately after it was started. The following errors were observed in the logs:

Upon researching the -612 error code, the following information is provided: "A non-unique name was specified where a unique name is required. Column names must be uniquewithin an index, a table, or a view, and in the UPDATE OF clause of a trigger definition."
What is the most likely cause of this issue, and how should it be rectified?
