This functionality is provided through PL/SQL and Java APIs.XMLType can be used in PL/SQL, in Java using JDBC, and in the Oracle Data Provider for . This powerful and relatively new datatype will be used extensively throughout this article. Oracle’s XML implementation gives us the flexibility to store data in two different ways: as structured and unstructured storage.

The WHERE clause specifies which record(s) that should be updated.
XML data is commonly used in today’s production systems and is a major part of database implementations.
You can verify that XML DB has been installed by simply running the SQL below: The XML DB schema and its objects can also be checked to see that Oracle XML DB has been installed.
The SQL/XML standard has been under development to provide a mechanism that allows us to generate XML from a relational query and, conversely, provide the ability to deliver SQL data from XML documents.It can also be used as a datatype for parameters and variables.Built-in XML methods operate on the content of a document by allowing us to create, extract, and index XML data.Indexing can be performed using b-tree, text indexing, and function-based indexes.In effect, XMLType data combined with XPath access can be used to look inside a document.This can be done by creating an XMLType view over existing relational data.
