Hi Keith,
It seems like the basic code path you have there should work. You say you are
doing a number of successive updates--maybe the conflicting update is coming
from elsewhere in your XQuery statement?
For example, this works both when the document exists and when it does not:
let $uri := "/hello.xml"
let $new := <bar>new node</bar>
return
if ( xdmp:estimate(fn:doc($uri)) eq 0 )
then ( xdmp:document-insert($uri, <foo>{$new}</foo>), "inserted new document" )
else ( xdmp:node-insert-child(fn:doc($uri)/foo, $new), "added new child node" )
What is the exact exception you are getting? Also, what is the entire query?

Subject: [MarkLogic Dev General] Avoiding conflicting document-insert()
I'm trying to do a number of updates in successive order and then write
information to a history file.
My problem is that when I write the history I don't know if the history file
has already been created.
Here is the code path:
if(xdmp:estimate(fn:doc($history-uri))) then
xdmp:node-insert-child(fn:doc($history-uri)/cms:events,$event)
else
xdmp:document-insert( $history-uri,
<cms:events>{$event}</cms:events>,
(xdmp:permission("cms","read"),xdmp:permission("cms","update")),
"http://ldschurch.org/cms/history";
)
The problem is that I am getting conflicting document-inserts(). Apparently
xdmp:estimate(fn:doc()) isn't absolute at determining if a document exists or
not.
Is there an absolute way to know if a document exists so that I don't try
to create it again?
Thanks,
Keith L. Breinholt
