OBJECT_VALUE AS "p" RETURNING CONTENT) AS VARCHAR2(30)); REFERENCE COUNT(*) -------------------------------- ---------- TFOX-20021009123337784PDT 3 XQuery API for Java (XQJ), also known as JSR-225, provides an industry-standard way for Java programs to access XML data using XQuery.

Its expressions and their results are not necessarily XML data. It lets you evaluate XQuery expressions against XML data sources and process the results as XML data.

Expression2 uses an if expression to determine the new value of the Labor Hours attribute.

element SELECT x.query(' /Root/Product Description') FROM T -- update the Product Name attribute value UPDATE T SET x.modify(' replace value of (/Root/Product Description/@Product Name)[1] with "New Road Bike" ') -- verify the update SELECT x.query(' /Root/Product Description') FROM T This example replaces values in a manufacturing instructions document stored in a typed XML column.

It's not specific for Oracle but a W3C Recommendation implemented many other XML tools too.

I need to update the '105' answer to be '205.' I have done something similar in the past using UPDATEXML.

You can specify the if expression in Expression2 of the replace value of XML DML statement, as shown in the following example.

OBJECT_VALUE COLUMNS reference VARCHAR2(28) PATH 'Reference', lineitem XMLType PATH 'Line Items/Line Item') t, XMLTable('Line Item' PASSING t.lineitem COLUMNS lineno NUMBER(10) PATH '@Item Number', upc VARCHAR2(14) PATH 'Part/@Id', description VARCHAR2(128) PATH 'Description', quantity NUMBER(10) PATH 'Part/@Quantity', unitprice NUMBER(12,2) PATH 'Part/@Unit Price') li WHERE t.reference = 'EABEL-20021009123336251PDT'; SELECT reference, userid, shiptoname, specialinstructions FROM purchaseorder_table; REFERENCE USERID SHIPTONAME SPECIALINSTRUCTIONS -------------------------------- -------- ------------------------------------------------ ------------------- EABEL-20021009123336251PDT EABEL Ellen S.Likewise, XML developers can leverage the power of XML standards while working in the context of a relational database.instances contain hidden columns that store this extra information that does not quite fit in the SQL object model.If you update the text node of an element to null, Oracle removes the text value of the element, and the element itself remains but is empty.In most cases, this function materializes an XML document in memory and updates the value.In modifying a typed XML instance, must be an expression that can be atomized. The following examples of the replace value of XML DML statement illustrates how to update nodes in an XML document.
