Hi Alvaro,

yes, Koha stores the complete record as MARCXML and only some fields are mapped to database columns. You can see the mappings in Administration > Koha to MARC mappings. Be careful, after changing it you need to run a script to populate database fields correctly. The MARC record is stored in either biblioitems.marcxml (older versions) or biblio_metadata.metadata (current versions) and can be queried using the ExtractValue function. You can find examples in the reports library on the wiki:

Hope this helps,

Katrin

Hi

How can I do a MySQL search for all the records/items with an specific value in an specific marc field Xx?

I've looked at the bilblio and related tables but I'm unable to find a table with marcs fields info. I saw some marcxml fields however; are marc values stored there and I need to xlmparse that info to get an specific value?

Regards
