Error inserting a new record in Base

[TWells]

I have been using Base for a while, (years), with a rather simple database. I tried to create a new record on the form that I have been using without any changes since the beginning and I’m getting this error.

Error inserting the new record
firebird_sdbc error:
*violation of PRIMARY or UNIQUE KEY constraint “INTEG_3” on table “Library”
*Problematic key value is (“Barcode” = ‘0110501642778’)
caused by
‘isc_dsql_execute’

The barcodes are always 13 numbers and none of the formatting has been changed. Any ideas on how to fix this?

Windows 10 pro
LibreOffice version 7.5.2.2

Are you sure, you have not scanned this barcode before? All this error says is: The valu is already in the table, and the definition allows no second entry for the same value.

Thank you Wanderer!

I always search for the items by an item number that is shorter but after your response, I tried the barcode and found an entry with a different item number. So the item had been replaced and my record wasn’t updated. Next time I’ll do a better search before asking. Thank you for providing a quick and accurate answer.
