ÉS a végső megoldás ez lett!
select row_id, daten
from
(select row_id,
replace(
replace(
replace(
xmlserialize(XMLAGG(XMLELEMENT(NAME "x", daten) ) as varchar(32672))
, '</x><x>', ',')
, '<x>', '')
, '</x>', '') as DATEN
from DB.TÁBLA
where mand_id = 'VALAMI'
and scito_tst_ab > current timestamp -5 hour
group by row_id)
where daten like '%2233%COMO%9601201%2233%INT%U_AVS_W_750000%2233%ISIN%DE0007500001%2233%VALO%412006%2233%WM%750000%'
;
Plug and Pray... :)
