     createfolders  IN  BOOLEAN := FALSE)
 RETURN BOOLEAN;

Given a REF to an existing XMLType row, creates a resource whose contents point to that row. That row should not already exist inside another resource:

DBMS_XDB.CREATERESOURCE(
     abspath        IN  VARCHAR2,
     datarow        IN  REF SYS.XMLTYPE,
     createfolders  IN  BOOLEAN := FALSE)

DBMS_XDB.CREATERESOURCE( 
     abspath        IN  VARCHAR2,
     data           IN  BFILE,
     csid           IN  NUMBER :=0,

Parameter Description

abspath

Absolute path of the resource to create. The path name's parent folder must already exist in the hierarchy. In other words, if /foo/bar.txt is passed in, then folder /foo must already exist.

data

The new resource's contents. The data will be parsed to check if it contains a schema-based XML document, and the contents will be stored as schema-based in the schema's default table. Otherwise, it will be saved as binary data.

datarow

REF to an XMLType row to be used as the contents

csid

Character set id of the document. Must be a valid Oracle ID; otherwise returns an error.

If CSID is not specified, or if a zero CSID is specified, then the character set id of the document is determined as follows:

  • From the abspath extension, determine the resource's MIME type.

  • If the MIME type is */xml, then the encoding is detected based on Appendix F of the W3C XML 1.0 Reference at http://www.w3.org/TR/2000/REC-xml-20001006;

  • Otherwise, it is defaulted to the database character set.

UPDATERESOURCEMETADATA Procedures

This procedure updates metadata for a resource. The procedure takes in a resource identified by absolute path and the metadata in it to replace identified by its REF. It replaces that piece of metadata with user-defined metadata which is either in the form of a REF to XMLTYPE or an XMLTYPE.

Syntax

Can be used to update schema-based metadata only. The new metadata must be schema-based:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath  IN VARCHAR2,
   oldmetadata    IN   REF SYS.XMLTYPE,
   newmetadata    IN   REF SYS.XMLTYPE)
 

Can be used to update schema-based metadata only. The new metadata must be schema-based or nonschema-based:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath        IN   VARCHAR2,
   oldmetadata    IN   REF SYS.XMLTYPE,
   newmetadata    IN   XMLTYPE);
 

Can be used for both schema-based and nonschema-based metadata:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath        IN   VARCHAR2,
   oldns          IN   VARCHAR2,
   oldname IN VARCHAR,
   newmetadata IN XMLTYPE);
 

Can be used for both schema-based or nonschema-based metadata. New metadata must be schema-based:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath       IN   VARCHAR2,
   oldns         IN   VARCHAR2,
   oldname       IN   VARCHAR,
   newmetadata   IN   REF SYS.XMLTYPE);

Parameters

Table 148-59 UPDATERESOURCEMETADATA Procedure Parameters

Parameter Description

abspath

Absolute path of the resource

oldmetadata

REF to the old of metadata

newmetadata

REF to the new, replacement metadata (can be either schema-based or nonschema-based depending on the overload)

oldns

Namespace identifying old metadata

oldname

Local name identifying old metadata


Usage Notes

In the case of REF, it stores the REF in the resource and the metadata is stored in a separate table. Uniqueness of REFs is enforced. In the case where the XMLTYPE is passed in, data is parsed to determine if it is schema-based or not and is stored accordingly.
