Teradata Database provides the XML data type for XML data. You can use it in the same way as other SQL data types supported by Teradata.
Using the XML type, you can store XML content in Teradata Database in a compact binary form that preserves the information set of the XML document, including the hierarchy information and type information derived from XML validation. The document identity is preserved as opposed to XML shredding, which only extracts values out of the XML document.
- XSD validation
- XPath and XQuery-based queries
- XSLT transformations of XML content
While a common use of the XML type instance is to represent a single XML document, it can also represent a sequence of items where an item is an element, attribute or even an atomic value.
- Fragments of XML documents, such as nodes like elements, attributes, or text
- Values of XML schema predefined simple types, such as string or int
