The reason for the XDMP-UNEXPECTED error is that your query has no return statement (although the code is formatted to look as if it does). In pseudo-code, the main query is (ignoring the variable declarations):
let $emails_with multiple_policies :=
for [iteration]
let [variable assignment]
where [condition]
return
( stuff to return)
The return clause is parsed as part of the variable assignment for $emails_with
multiple_policies. Thus the main query itself has no return clause and is
incomplete. To fix that you probably want to add one line to the variable
assignment so that it reads
let $emails_with_multiple_policies :=
for $em at $i in
fn:distinct-values(fn:collection($coll)//insured_email/text())
let $policies :=
fn:count(fn:distinct-values(fn:collection($coll)//policy[insured_email/text() =
$em]/policy_num/text()))
where $policies > 1
return $em
The query still won’t succeed as there are undefined variables remaining but
hopefully that sets things on the right track.
