Hi Nalisha,
It sounds like you want to find items with identical barcodes (ignoring a
leading zero), then delete their related biblios? If that's the case then
this report should return the list of related biblios that you can then
feed to Batch item/record deletion tools.
SELECT biblionumber
FROM items i
WHERE i.barcode IN (SELECT CONCAT('0', barcode) FROM items)
To be perfectly clear, this returns the *biblionumber* for the associated
bibliographic records for items with barcodes like "2412" where another
item exists with barcode "02412". It would retain your manually created
records. So if you were to feed this list of biblios to the batch record
deletion tool
<https://koha-community.org/manual/19.05/en/html/tools.html#batch-record-deletion-label>
you
would end up with no duplicates. I believe this also causes the orphaned
item records to be removed as well. I tested it briefly on our system by
creating a fake item with a duplicate barcode plus leading zero and it did
retrieve the intended result.
There was no screenshot attached to your email, FYI. Perhaps the mailing
list didn't allow it.
Best,
