Summary

[DEPRECATED: use xdmp:eval with the database option instead] Returns the result of evaluating a string as an XQuery module in a given database.

Parameters
$xquery The XQuery string to be evaluated. If the XQuery string contains double quotes ("), surround the string with single quotes (').
$ID The database ID, from xdmp:database("db_name"), xdmp:security-database(), or xdmp:schema-database().
$vars The external variable values for this evaluation. This must be a sequence of even length, alternating QNames and items. Each QName and item pair specify a variable name and value.
$modules The modules database for processing module imports. The empty sequence specifies the current modules database.
$root The root path for modules. The empty sequence specifies the current root.

Example

  xdmp:eval-in("1+1",2348790529)
  => 2

Example

xquery version "0.9-ml"
declare namespace my='http://mycompany.com/test'

let $s :=
      "xquery version '0.9-ml'
       declare namespace my='http://mycompany.com/test'
       define variable $my:x as xs:string external
       concat('hello ', $my:x)"
return
    (: evaluate the query string $s using the variables
       supplied as the second parameter to xdmp:eval :)
    xdmp:eval-in($s,
                 xdmp:database("Documents"),
		 (xs:QName("my:x"),
		 "world"))
