ciara who is she dating now - Updating xmltype

The XQuery expression used in this example is identical to the one used in Example 5-6; the result of evaluating the XQuery expression is a sequence of table, so the overall SQL-query result set has only ten rows. Similarly, Oracle provides two mid-tier XQJ implementations for accessing these two XQuery engines.

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. Both implementations are part of Oracle XML Developer's Kit (XDK).

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

This can be an expression that returns a simply typed node, because data() will be used implicitly.

If the value is a list of values, the update statement replaces the old value with the list.

The following examples of the replace value of XML DML statement illustrates how to update nodes in an XML document.In the following example, a document instance is first assigned to a variable of xml type.You can specify the if expression in Expression2 of the replace value of XML DML statement, as shown in the following example.
