You typically use XQuery with Oracle XML DB in the following ways.

An XQuery namespace declaration has no effect outside of its XQuery expression.

Example 5-15 illustrates use of a namespace declaration in an XQuery expression.

A typical use case for this feature is to access data stored in remote databases from a local Java program.

VARCHAR2(20):= '715515009058'; -- Part ID result XMLType; doc DBMS_XMLDOM. DOMNode; buf VARCHAR2(20000); BEGIN sql_stmt := 'SELECT XMLQuery( ''for $i in fn:collection("oradb:/OE/PURCHASEORDER") '

In Example 5-10, these empty sequences are part of the overall result set of the SQL query, which contains 132 rows, one for each of the rows in table ' PASSING OBJECT_VALUE RETURNING CONTENT) FROM purchaseorder; XMLQUERY('FOR$IIN/PURCHASEORDERWHERE$I/COSTCENTEREQ"A10"AND$I/USEREQ"SMCCAIN"RET -------------------------------------------------------------------------------- 'Regular', contact VARCHAR2(20) PATH 'Name') xtab; POREF PRIORITY CONTACT -------------------- -------- -------------------- SKING-20021009123336 Fastest Steven A.

They then insert that data into a relational table. Example 5-20 defines and uses a PL/SQL procedure to extract data from an XML purchase-order document and insert it into a relational table. To declare a namespace prefix for use in an to extract data from an XML purchase-order document.
