[Koha] How can one batch delete null barcoded item records?

[Raphael Muonga]

We are using Koha 3.2 on Ubuntu.
Our Assistant Librarian generated multiple item records (100) with
null barcode number with same title.
We have failed to delete as  "delete this record in Edit is not doing
anything".  And worse still the Tools > Batch Item Deletion  cannot
work with null barcode.

How cann we delete these records with are sequentially number as item
#3315 to #3414? Any SQL solution or whatever that can do?
