Use db:add from module. no updating expression allowed.
Hi!
If there is a module:
xquery version "1.0";
module namespace
m="http://www.host.ru/xquery/m";
declare variable $m:db :=
"mydb";
declare function m:up() as xs:string {
let $new-doc :=
<root-element><item>1</item></root-element>
let $update :=
db:add($m:db, document { $new-doc }, "id1.xml")
return
"Result
string"
};and I use it from python API or basexclient utility. Use as:
xquery import module namespace m="http://www.host.ru/xquery/m" at "/tmp/test.xqy"; m:up()
I get an error:
Stopped at line 8, column 4 in /tmp/test.xqy: [XUST0001] Let expression: no updating expression allowed.
What could be the problem?
Hi there,
i guess you have to define the function as updating [1].

Many thanks!
Is working correctly now.
Corrected code:
xquery
version "1.0";
module namespace m="http://www.host.ru/xquery/m";
declare
variable $m:db := "mydb";
declare updating function m:up() {
let
$new-doc := <root-element><item>1</item></root-element>
return
db:add($m:db, document { $new-doc }, "id1.xml")
