Hi Christian,
Thanks for that. That's exactly what I was hoping for (and I thought I tried that, but must have done something wrong).
Now for the trickier part of the problem:
Let's say that I want to add a file to the database, but I want to do it through a server-side XQuery, so that it can validate, etc. Can I do this using the context of the call, or do I have to pass the name of the database as an argument?
e.g.
db:add("Test", <a/>, "doc.xml") (: Works, but has hardcoded the database :)
==8<=========================
let $db := request:parameter('param1') return db:add($db, <a/>, "doc.xml") (: Works, but had to pass the database name as a parameter :)
==8<=========================
db:add(., <a/>, "doc.xml") (: Doesn't work, and I didn't expect it to, but would be ideal :)
Is there any way to achieve this? There isn't anyway of converting the current context into an expression containing the database (and path) is there?
Thanks, Luke

Hi Luke,
However, when I execute an XQuery I would like it to run on a particular database. Is there anyway to achieve this without passing the database as an argument to the query?
If you address a database in your URL, it will be bound to the context of your query, which can be obtained via a simple dot (.). For example, run the following query to get the number of documents in your 'Test' database:
http://localhost:8984/rest/Test?query=count(.)
I have added another example in our documentation [1]. The given query can also be written to a file and evaluated with 'run'.
Hope this helps, Christian
