XML data integrity

When you need to ensure that your XML documents adhere to certain rules or fulfill certain processing requirements, you can perform additional XML data integrity checks or specify additional conditions that must be met before an action is performed.

Several different methods for ensuring XML data integrity are available; which method you choose depends on your specific data integrity and processing requirements.

If you are indexing XML documents, you can also enforces uniqueness within the XML column across all documents whose nodes are qualified by the XML pattern you are indexing on. See "UNIQUE keyword semantics" for more information.
