you write:
"I would like to preprocess the xml before entering postgres, and stream
it with the copy command." but why? I'm inferring that you want to
dynamically generate XML as its queried by postgres?
Just curious,

Hi Steve,
yes, it certainly does. At this point, I'd settle for adding an
attribute like "recordID", but that's exactly it. I'll take a closer
look at "group by" a bit later, thanks for the pointer. See also:

return(

Pardon, output for a simpler example:
the FLWOR:
xquery version "3.0";
let $y := 99

let $y := $y - 1

is it not possible to decrement $y without using some external scripting

So, I guess a two-fold question: how to import a JSONArray with Java,
and how to even know what resource isn't found. Doesn't seem likely to
be the JSONObject as I've inspected it just prior to invoking Add.

I'm looking at the Java examples, but how would I add a POJO, or
collection of POJO's, to BaseX? Jaxb looks to certainly be an option to
serialize to XML, but what would be some alternate approaches?

I'll read your response more carefully, but key takeaway is to maybe use
something else? I'm futzing with powershell, seems reasonable for the
task (if a bit odd).

I'd have to experiment more, but I believe that if I kept the filename
static each iteration of Replace would simply write over the previous
tweet so that only one tweet was ever being stored to the db. Only by
changing the name was I able to add multiple tweets with Replace. (I
think.)
tand there is that when creating the Replace
command the "primary key" would seem to be the id_str from the tweet --
which is fine. But that relates to a filename xxx.xml?

From SO (and the fine manual), the solution is to use: basex -i

Very interesting. I'm sure this can be piped or simply written to a
