[xquery-talk] Grouping Scope and counters

[Ihe Onwuka]

for $x at $i in blah
group by $x/@a
return
if ($i mod 10000 eq 0) then ..... else .....


Now the problem is that XQuery (of the eXist variety) denies knowledge of
the existence of the $i variable in the return clause. Presumably this is
because the group construct interferes with the lexical scoping.

I do not have to do this with XQuery as I can solve it downstream but I
would be interested in learning more about this scenario.

Yes, the original implementor left a todo comment in the code ;-) The $i variable should be in scope. I’ve just submitted a pull request for this.
