7 Updating Relational Databases

---

DataDirect XQuery supports updates to relational database tables from inside an XQuery by providing three built-in functions. These functions are:

ddtek:sql-insert
ddtek:sql-update
ddtek:sql-delete

The DataDirect XQuery relational update functionality is an extension of the XQuery Update Facility (XUF). To learn about DataDirect XQuery’s support for XUF and how to use XUF to update XML, see Chapter 8, "The XQuery Update Facility."
