Any of the following SQL data types can be used as the second argument: argument is an XML value.

The query in Example 4-2 extracts the scalar value of node SELECT XMLCast(XMLQuery('/Purchase Order/Reference' PASSING OBJECT_VALUE RETURNING CONTENT) AS VARCHAR2(100)) "REFERENCE" FROM purchaseorder WHERE XMLExists('/Purchase Order[Special Instructions="Expedite"]' PASSING OBJECT_VALUE); REFERENCE ---------------------------- AMCEWEN-20021009123336271PDT SKING-20021009123336321PDT AWALSH-20021009123337303PDT JCHEN-20021009123337123PDT AWALSH-20021009123336642PDT SKING-20021009123336622PDT SKING-20021009123336822PDT AWALSH-20021009123336101PDT WSMITH-20021009123336412PDT AWALSH-20021009123337954PDT SKING-20021009123338294PDT WSMITH-20021009123338154PDT TFOX-20021009123337463PDT 13 rows selected.

Table 3-1 summarizes some advantages and disadvantages to consider when selecting your Oracle XML DB storage option.

Storage options are also discussed in Table 1-3, "XML Storage Options: Structured or Unstructured" and Chapter 2, "Getting Started with Oracle XML DB". For example, if you are sure that a given source XML document is valid, you can provide an argument to the constructor that disables the type-checking that is otherwise performed.

In addition, if the source data is not encoded in the database character set, an OCIEnv *envhp; OCIError *errhp; OCISvc Ctx *svchp; OCIStmt *stmthp; OCIServer *srvhp; OCIDuration dur; OCISession *sesshp; oratext *username = "QUINE"; oratext *password = "CURRY"; oratext *filename = "AMCEWEN-20021009123336171PDT.xml"; oratext *schemaloc = " Source/xsd/purchase Order.xsd"; /*--------------------------------------------------------*/ /* Execute a SQL statement that binds XML data */ /*--------------------------------------------------------*/ sword exec_bind_xml(OCISvc Ctx *svchp, OCIError *errhp, OCIStmt *stmthp, void *xml, OCIType *xmltdo, Ora Text *sqlstmt) /*--------------------------------------------------------*/ /* Initialize OCI handles, and connect */ /*--------------------------------------------------------*/ sword init_oci_connect() /*--------------------------------------------------------*/ /* Free OCI handles, and disconnect */ /*--------------------------------------------------------*/ void free_oci() void main() When loading large XML files consisting of a collection of smaller XML documents, it is often more efficient to use Simple API for XML (SAX) parsing to break the file into a set of smaller documents, and then insert those documents.

If multiple text nodes are referenced in the XPath expression, the text nodes are collapsed into a single text node value.For example, set long 500 set pagesize 100 set linesize 132 -- create table XML_TABLE of XMLType; Table created. GETCLOBVAL() -------------------------------------------------------------------------------- SELECT object_value FROM PURCHASEORDER WHERE exists Node(object_value,'/Purchase Order[Special Instructions="Expidite"]') = 1; OBJECT_VALUE ---------------------------------------------------------------------------------- extracts the node or a set of nodes from the document identified by the XPath expression.-- create table TABLE_WITH_XML_COLUMN( FILENAME varchar2(64), XML_DOCUMENT XMLType ); Table created. The extracted nodes can be elements, attributes, or text nodes.XPath is a W3C recommendation for navigating XML documents. It provides a rich set of operations that walk the tree of nodes and also apply predicates and node test functions.Applying an XPath expression to an XML document can result in a set of nodes.

However, the majority of techniques introduced here can also be used to manage other types of XML documents, such as containing unstructured or semistructured data.
