xdmp:document-insert

xdmp:document-insert(
   $uri as xs:string,
   $root as node(),
   [$options as (element()|map:map)?]
) as empty-sequence()

Summary

Inserts a new document into the database if a document with the specified URI does not already exist. If a document already exists at the specified URI, the function replaces the content of the existing document with the specified content (the $root parameter) as an update operation. In addition to replacing the content, xdmp:document-insert replaces any permissions, collections, and quality with the ones specified (or with the default values for these parameters, if not explicitly specified). Also, if a properties document exists at the same URI, that properties document (including any content it contains) is preserved.

Parameters
uri The URI of the document to be inserted.
root The root node. The root node can be one of JSON format, XML format, binary (BLOB) format, or text (CLOB) format.
options Options with which to customize this operation. You can specify options as either an options XML element in the "xdmp:document-insert" namespace, or as a map:map. The options names below are XML element localnames. When using a map, replace the hyphens with camel casing. For example, "an-option" becomes "anOption" when used as a map:map key. This function supports the following options, plus the options from the xdmp:http-get function.
permissions
Specify permissions for the document. If not supplied, the current user's default permissions are applied. The default value used for permissions can be obtained by calling the xdmp:default-permissions function. A document that is created by a non-admin user (that is, by any user who does not have the admin role) must have at least one update permission, otherwise the creation will throw an XDMP-MUSTHAVEUPDATE exception. When expressing options using a map:map, use the "object" format for permissions; see the output-kind parameter of xdmp:permission and xdmp:default-permissions.
collections
The collection URIs for collections to which this document belongs. If not supplied, the document is added to the current user's default collections. For each collection that is protected, the user must have permissions to update that collection or have the any-collection privilege. For each unprotected collection, the user must have the unprotected-collections privilege. The default value used for collections can be obtained by calling the xdmp:default-collections function. When expressing options as an XML element, specify the collection URIs in <collection> child elements of this option, one URI per child. When expressing options as a map:map, specify the value of the collections key as a sequence of collection URIs.
quality
The quality of this document. A positive value increases the relevance score of the document in text search functions. The converse is true for a negative value. The default value is 0.
forests
Specifies the IDs of one or more forests in which this document is inserted. Each forest is specified in a separate <forest> element. If the document already exists in the database and if forests is not specified, it will remain in its existing forest. If no such forest exists or if no such forest is attached to the context database, an error is raised. If multiple forests are specified, the document is inserted into one of the specified forests. If the document exists and the forest in which it is stored is set to delete-only, then the forests option must include one or more forests that allow updates, otherwise an exception is thrown.

If you have local disk failover enabled, specify the ID of the master forest. In the event of a failover, MarkLogic server will automatically redirect documents to the replica forest. Specify the ID of the replica forest will result in a "forest not in database" error.

metadata
Specifies key-value pairs representing certain metadata associated with the document. Metadata values are strings. Non-string values are converted to strings. When you express options as an XML element, the value of a metadata element is a serialized map containing the key-value pairs. When you express options as a map:map, the value associated with "metadata" key is also a map:map.

Required Privileges

If a new document is inserted, the unprotected-uri privilege (only if the URI is not protected), the any-uri privilege, or an appropriate URI privilege is also needed. If adding an unprotected collection to a document, the unprotected-collections privilege is needed; if adding a protected collection, the user must have either permissions to update the collection or the any-collection privilege.

Usage Notes

If a document is inserted with the admin user and its default permissions, the document will only be accessible by a user with the admin role as the default permissions of the admin user is empty.

Example

xdmp:document-insert(
    "/example.xml", <a>aaa</a>,
    <options xmlns="xdmp:document-insert">
      <metadata>{
        map:map() => map:with("w", "world")
                  => map:with("h", "hello")
      }</metadata>
      <permissions>{xdmp:default-permissions()}</permissions>
    </options>)

Example

(: Insert with perm, collection, and quality options. Notice that this
 : example adds to, rather than replaces, the default collections. :)
xdmp:document-insert(
    "/example.xml",
    <a>aaa</a>,
    <options xmlns="xdmp:document-insert">  
      <permissions>{xdmp:default-permissions()}</permissions>
      <collections>{
        <collection>/my/additional/collection</collection>,
        for $coll in xdmp:default-collections()
        return <collection>{$coll}</collection>
      }</collections>
      <quality>10</quality>
    </options>)

Example

(: Expressing options as a map instead of an element :)
xquery version "1.0-ml";
xdmp:document-insert("/example.xml", <a>aaa</a>,
  map:map() => map:with("collections", ("coll1","coll2"))
            => map:with("quality", 2)
            => map:with("permissions", 
                        (xdmp:default-permissions("objects"),
                         xdmp:permission("some-role", "read", "object")))
)

Example

(:
   Specify the valid start and end time for a temporal document.
:)
xdmp:document-insert(
    "/example.xml",
    <root>new content here</root>, 
    <options xmlns="xdmp:document-insert">  
      <metadata>{
        map:map() => map:with("valid-start", "2014-06-03T14:13:05.472585-07:00")
                  => map:with("valid-end", "9999-12-31T11:59:59Z")
      }</metadata>
    </options>)

Example

xquery version "1.0-ml";
(: create a text document :)
xdmp:document-insert("/text-doc.txt",
   text { "This is a text document." } )
