Hi
IIRC, Koha's batch modification tool does not work with the MARC21 control
fields (i.e. 000 - 009).
However, since you only wish to switch the value of a single position in
the leader, you may be able to do it.
For example, to update the 17th position of LDR (Encoding level) to "2"
(full level, material not examined) for biblionumber 1 you could do this:
UPDATE biblio_metadata
SET metadata = UpdateXML(metadata, '//leader', CONCAT('<leader>',
SUBSTRING(ExtractValue(metadata, '//leader'), 1, 17), '2',
SUBSTRING(ExtractValue(metadata, '//leader'), 19, 6), '</leader>'))
WHERE biblionumber = 1;
cheers
