Using RAW Mode
RAW mode transforms each row in the query result set into an XML element that has the generic identifier <row>, or the optionally provided element name. By default, each column value in the rowset that is not NULL is mapped to an attribute of the <row> element. If the ELEMENTS directive is added to the FOR XML clause, each column value is mapped to a subelement of the <row> element. Together with the ELEMENTS directive, you can optionally specify the XSINIL option to map NULL column values in the result set to an element that has the attribute, xsi:nil="true".
You can request a schema for the resulting XML. Specifying the XMLDATA option returns an in-line XDR schema. Specifying the XMLSCHEMA option returns an in-line XSD schema. The schema appears at the start of the data. In the result, the schema namespace reference is repeated for every top-level element.
The BINARY BASE64 option must be specified in the FOR XML clause to return the binary data in base64-encoded format. In RAW mode, retrieving binary data without specifying the BINARY BASE64 option will result in an error.
The queries in the following examples show how FOR XML RAW mode is used with various options. Many of these queries are specified against the bicycle manufacturing instructions XML documents that are stored in the Instructions column of the ProductModel table. For more information about the XML instructions, see xml Data Type Representation in the AdventureWorks Database.
