[MarkLogic Dev General] db:fields

[Danny Sokolsky]

You can also use the Admin API to help you construct the field (or other indexing options).  Just construct the elements, do not save them to the configuration (that is, do not use admin:save-configuration).  Here is an example:

xquery version "1.0-ml";

import module namespace admin = "http://marklogic.com/xdmp/admin" 
		  at "/MarkLogic/admin.xqy";
declare namespace db="http://marklogic.com/xdmp/database";
		
		
  let $config := admin:get-configuration()
  let $dbid := xdmp:database("Documents")
  let $fieldspec := admin:database-field("myField", fn:true() )
  let $includeelem :=   
    admin:database-included-element("http://myuri/namespace",
    "element-name", 1.0, "", "myAttribute", "some value")

  return
  admin:database-add-field-included-element(
    admin:database-add-field($config, $dbid, $fieldspec), $dbid, 
    "myField", $includeelem)

    //db:database[db:database-name eq "Documents"]
    //db:field[db:field-name eq "myField"]

=>
<field xmlns="http://marklogic.com/xdmp/database" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <field-name>myField</field-name>
  <include-root>true</include-root>
  <included-elements>
    <included-element>
      <namespace-uri>http://myuri/namespace</namespace-uri>
      <localname>element-name</localname>
      <weight>1</weight>
      <attribute-namespace-uri/>
      <attribute-localname>myAttribute</attribute-localname>
      <attribute-value>some value</attribute-value>
    </included-element>
  </included-elements>
  <excluded-elements/>
</field>
