Hi,
I would like to send XML file to the Tamino database in order to only update values of defined in my schema elements. I don’t want to add new instances but only update values.
How can I configure database to achive such result?

Regards

well, if you want to replace a whole document, this can be done using the _process command with palin URL addressing (giving ino:id or ino:docname of the document to be updated). if you want to do something like the following: database contains
cd
you send
x
and expect the database to contain
xd
afterwards - this cannot be done easily.
You have several options if you want to achieve this behaviour:

  • send an XQuery update instead
    (e.g.
    for $d in input()/Root do update
    replace $d/E1/text() by “x”)
    (maybe one can even find a generic formulation in XQuery)
  • implement a trigger that does the action when the “change document” is stored
