And, at the risk of stating the obvious, if your application requires an update that is conflicting in a single transaction, you can always do it in multiple transactions.

Two xdmp:document-insert()s on the same URI -> conflict 2. Two xdmp:node-replace()s on the same doc, same node -> conflict 3. Two xdmp:node-replace()s on the same doc, different nodes -> no conflict 4. Two xdmp:node-insert-after()s on the same node -> conflict (because order would matter?) 5. Two xdmp:document-add-properties()s on the same doc -> conflict 6. Two xdmp:document-set-property()s on the same doc, same property -> conflict 7. Two xdmp:document-set-property()s on the same doc, different properties -> no conflict 8. xdmp:document-insert() and xdmp:document-add-properties() on the same doc -> conflict I suppose I could just set up a test a run through them all to find out. ________________________________ From: [email protected] Date: Thu, 28 Oct 2010 08:49:08 -0700 To: [email protected] Subject: Re: [MarkLogic Dev General] Conflicting updates Just to clarify, the rule on conflicting updates is that all update actions you specify as part of a request should be able to be executed in any order with the same result. If that's not true, it's a conflicting update. There's various reasons for this, the easiest of which is that XQuery is a functional language and this is an aspect of that. It means you can't, for example, add a node and then give it a child node. Because that's order dependent. Nor can you delete a node and then delete its parent. Again, order dependent. You very much can, however, update the same document multiple times in the same transaction, so long as you're dealing with different parts of the document so that execution order of updates isn't important. Writing the same document multiple times in a transaction would be, as Ryan says, conflicting. -jh- On Oct 28, 2010, at 3:08 AM, [email protected]<mailto:[email protected]> wrote: That error usually means that two updates are being attempted on a document in the same transaction. I looked at the code and I'm not seeing two updates so I'm wondering if maybe two docs are being written with the same URI in the set of documents you are loading? ________________________________ From: [email protected]<mailto:[email protected]> To: [email protected]<mailto:[email protected]> Date: Thu, 28 Oct 2010 12:11:45 +0530 Subject: [MarkLogic Dev General] (no subject) Hi, I am using the attached files to manipulate the xml data and then insert in ML DB using record loader.
