The xmltext directive is used to incorporate an XML document (or section of the document) stored in a column of the record into the resulting document. Imagine a scenario in which you have created a database table, but the nature of the business is such that new information (and new columns) will often be added. In the past, I have used a solution that you can see in the Asset database in the InventoryProperty table:

SQL Server 2000 Stored Procedure & XML Programming
An XML alternative to this solution is to create a special column to store the overflow data. In the following statement, the Inventory table is created with a Properties column to store additional information in XML format:
CREATE TABLE [InventoryXML] ( [Inventoryid] [int] IDENTITY (1, 1) NOT NULL , [EquipmentId] [int] NOT NULL , [LocationId] [int] NOT NULL , [StatusId] [tinyint] NOT NULL , [LeaseId] [int] NULL , [LeaseScheduleId] [int] NULL , [OwnerId] [int] NOT NULL , [Rent] [smallmoney] NULL , [Lease] [smallmoney] NULL , [Cost] [smallmoney] NULL , [AcquisitionTypeID] [tinyint] NULL , [Properties] [text] NULL, ) ON [PRIMARY]
You can then insert information in the form of an XML document or its subset into the Properties column:
<Inventory CPU = "Pentium II" RAM = "64 MB" HDD = "6.4 GB" Resolution = "1024x768" Weight = "2 kg" Clock="366 MHz"/>
To integrate this information into the resulting XML document, you should use the xmltext directive:
1 as Tag, NULL as Parent, InventoryXML.InventoryID as [Inventory!1!InventoryID], InventoryXML.StatusID as [Inventory!1!StatusID], InventoryXML.Properties as [Inventory!1!Properties!xmltext] FROM InventoryXML ORDER BY [Inventory!1!InventoryID] FOR XML EXPLICIT SELECT
The following listing contains a partial result:
<Inventory InventoryID="1" StatusID="1"> <Properties

CPU="Pentium II" RAM="64 MB" HDD="6.4 GB" Resolution="1024x768" Weight="2 kg" Clock="366 MHz"/> </Inventory> <Inventory InventoryID="2" StatusID="2"/> ...
If AttributeName is specified (as in the preceding example), SQL Server uses this value instead of the tag name specified for the column (in the preceding example they were the same). If AttributeName is omitted, SQL Server appends the attribute to the list of attributes in the enclosing element:
1 as Tag, NULL as Parent, InventoryXML.InventoryID as [Inventory!1!InventoryID], InventoryXML.StatusID as [Inventory!1!StatusID], InventoryXML.Properties as [Inventory!1!!xmltext] FROM InventoryXML ORDER BY [Inventory!1!InventoryID] FOR XML EXPLICIT SELECT
The following listing displays a partial result:
<Inventory InventoryID="1" StatusID="1" CPU="Pentium II" RAM="64 MB" HDD="6.4 GB" Resolution="1024x768" Weight="2 kg" Clock="366 MHz"> </Inventory> <Inventory InventoryID="2" StatusID="2" ...
The author of a query using the xmltext directive assumes a huge responsibility for the validity of the content of the column. If the column does not contain wellformed XML, the results may be unpredictable.
SQL Server 2000 Stored Procedure & XML Programming
The xmltext directive is permitted (and meaningful) only with columns of character data types (varchar, nvarchar, char, nchar, text, ntext).
The id, idref, and idrefs Directives
The id, idref, and idrefs directives are used to modify schemas when the XMLData option of the For XML clause is specified. When the id directive is specified, elements receive an id attribute. Attributes specified using the idref directive can be used to reference elements with an id attribute. This kind of relationship is the XML equivalent of the foreign key relationship that you are used to in relational databases. The following example links Equipment.EquipmentId to Inventory.EquipmentId. These two columns are also linked by a foreign key relationship in the database.
SELECT 1 as Tag, NULL as Parent, Equipment.EquipmentID as [Equipment!1!EquipmentID!id], Equipment.Make as [Equipment!1!Make], Equipment.Model as [Equipment!1!Model], NULL as [Inventory!2!InventoryID], NULL as [Inventory!2!StatusID], NULL as [Inventory!2!EquipmentID!idref] Equipment
