Thank you Christian.

There is something faster than BaseX : its support !

Best regards,

Hi Fabrice,

I believe it should be sufficient to prepend the "updating" keyword before your function call [1]:

updating $builder(...)

Dear all,

I cannot find a way to tell the xquey engine that a function parameter of my high-order function is updating :

declare %updating function etebac:build-updating($file as xs:string, $builder as %updating function(*) ) {

for tumbling window $line in (file:read-text-lines($file))

start $start-item when etebac:record-header($start-item) = '01'

end $end-item when etebac:record-header($end-item) = '07'

let $doc := etebac:build-json($line)

let $start := format-date(xs:date($doc/date-ancien-solde), '[Y0001][M01][D01]')

let $stop := format-date(xs:date($doc/date), '[Y0001][M01][D01]')

let $doc-id := string-join(($doc/rib, $start, $stop), '-')

let $doc-path := string-join(

($doc/(banque, guichet, compte), $start || '-' || $stop), '/')

let $out-file := concat($doc-path, '.json')

where count($doc/operations/_) > 0

return

$builder(

  $doc-path,

  element json {

    attribute type { 'object' },

    element meta {

      attribute type { 'object' },

      element type { 'releve-operations' },

      element id { $doc-id }

    },

    element data {

      $doc/(*|@*)

    }

  }

)

};

I have a [XPTY0004] Function must not be updating: %updating function($path,$doc) a... error.

The outer call is :

import module namespace etebac = 'http://pch.cerfrance.fr/basex/modules/etebac' at 'etebac.xqm';

etebac:build-updating('D:\edi\banque\input\10278\10278_CMLACO_20160701 .183',

db:replace('test', ?, ?)

)

What have I to do to tag my $builder function reference as updating in the main body ?
