I have to disagree with you.
First, the code he provided is incorrect and will leave only duplicates in the table. Second, if implemented properly, it has some limitations:
- The table cannot have deleted records before this operation
- It requires to delete all records in the table that could be slow on the big table
- It requires creating a new index and on the big table it could take a long time
- It requires to recall almost all records in the table that could be time consuming on the big table also.
