Hm, using ExtractValue is slow, especially on big databases. As Magnus says in lot of use cases a quick access to 001 and 003 for matching is really helpful. We have started to map the biblioitems.ean to 001 for use in reports etc. as the 001 is so important to us. The column is indexed and not mapped by default in MARC21 - but it remains a bit of a workaround and I'd be happy about a real controlnumber column.
Hmm, ok, I think I'm convinced. We're still living in a MARC centric world, so there's no reason not to add it. And I doubt Koha will ever use the 001 instead of the 999$c, so even if it isn't ideal from a MARC perspective, it does seem like a practical move. I know I hate using ExtractValue in databases in the hundreds of thousands or millions of records O_O. -- You are receiving this mail because: You are watching all bug changes.
