It seems that I stumble on communication difficulties for this application area.

I imagine that join parameters can be passed
Hi Markus,
Could you please get specific and provide real use cases and examples?
Thanks,

Hi Markus,
Have you read the XQuery specifications? This section on joins, written by
one of the inventors of SQL, may be a helpful starting point:
https://www.w3.org/TR/xquery-31/#id-joins
The use case documents may also be helpful:

I am still trying to clarify corresponding development possibilities according
to
bigger numbers of entities together with for clauses.
(I hope that other meanings can be better distinguished

An example application was published already with the XQuery 3.1 specification
for the combination of information from three documents.

Here's one thing you may be asking - do you want to know how to specify a
join for n sources? If so, maybe this example will help:
declare variable $eng := (one, two, three, four);
declare variable $deu := (eins, zwei, drei, vier);
declare variable $ukr := (один, два, три, чотири);
declare
How about some custom logging?
for $i in (1 to 10)
return
if ($i = 4) then error()
else file:append-text-lines('C:\tmp\file',string($i))
There might be more sophisticated ways.

Greetings!
Is it possible to capture partial results from an interrupted query?
When I realize a query is taking too long for the data involved, it
might be helpful in correcting the mistake.
Thanks!

The string join yields a single item, which is assigned to

I think the question was, what if n is large or dynamic.
But then we fall back to needing a use case because the best strategy
depends on

Yes. ‒ Your enquiry points into a direction for which I am looking also for

Thanks!
That should do it!
