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
Alvaro
