Columns with a Name Specified as a Wildcard Character
If the column name specified is a wildcard character (*), the content of that column is inserted as if there is no column name specified. If this column is a non-xml type column, the column content is inserted as a text node, as shown in the following example:
SELECT EmployeeID "@EmpID", FirstName "*", MiddleName "*", LastName "*" FROM HumanResources.Employee E, Person.Contact C WHERE E.EmployeeID = C.ContactID AND E.EmployeeID=1 FOR XML PATH
This is the result:
If the column is of xml type, the corresponding XML tree is inserted. For example, the following query specifies "*" for the column name that contains the XML returned by the XQuery against the Instructions column.
SELECT ProductModelID, Name, Instructions.query('declare namespace MI="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/ProductModelManuInstructions" /MI:root/MI:Location ') as "*" FROM Production.ProductModel WHERE ProductModelID=7 FOR XML PATH go
This is the result. The XML returned by XQuery is inserted without a wrapping element.
<row> <ProductModelID>7</ProductModelID> <Name>HL Touring Frame</Name> <MI:Location LocationID="10">...</MI:Location> <MI:Location LocationID="20">...</MI:Location> ... </row>
