However, the document is not well-formed as there is no root element in the document. To add a root element, we need to execute the following script:.
Now suppose you want that CarId should be the attribute of the Car element rather than an element. You can do so with the following script:. We can add further nesting levels to an XML document. For instance, if we want Name, Make and Model elements to be nested inside another element CarInfo we can do so with the following script:. In the output, you will see a new element CarInfo that encloses the Name, Make and Model elements as shown below:. Finally, if you want to convert the elements Name and Make into an attribute of element CarInfo, you can do so with the following script:.
Save the above XML document with the name Cars. In this section, we will see how to do the reverse i. The document we will use is the document that we created in the last section. One node of the document looks like this:. Suppose we want to create a table with two columns that contain the values from the Name and Make attributes from the CarInfo element. We can do so using the following script:.
In the script above we declare an XML type variable cars. At this point in time, the XML document is loaded into the memory. Next, we create a handle for the XML document. It takes the handle and the document variable as parameters and creates an association between them. Explicit transactions are supported only with SQL batches and not when calling web methods. If you want to support transactions with your web method calls, put the transaction into the functionality called by the web method.
For example, if you expose a stored procedure as a web method, put your transaction context code in the stored procedure. The following code is a snippet of the header you will want to pass to start transactions. You need to set the transactionBoundary attribute of the environmentChangeNotifications header to true to use transactions.
The server will let you know whether or not the transaction was successfully begun and will send back a transactionDescriptor. This is similar to the sessionId in that you need to send this transactionDescriptor with every request that wants to perform an action that uses that transaction context. The following code is a snippet of the response from the server:. The following code snippet is the next request, with the sessionId and the transactionDescriptor passed along with the request:.
Over one session, you can have multiple transactions. Just make sure to keep track of the different transactionDescriptor values that are sent back from SQL Server. This class makes it easy for you to take an existing SOAP call and add the headers to it.
Since Books Online includes all the information you need to start using this class, we refer you there to get the sample code and the instructions for using that sample code. The XML web services in SQL Server have a number of performance counters that you can monitor to understand how your web services are performing. Table lists the performance counters included.

Privacy policy. Any XML declaration in the xml type column is not serialized. For example, the following query retrieves customer contact information such as the BusinessEntityID , FirstName , and LastName columns, and the telephone numbers from the AdditionalContactInfo column of xml type.
Because the query does not specify the ELEMENTS directive, the column values are returned as attributes, except for the additional contact information values retrieved from the xml type column. These are returned as elements. For example, the following query specifies MorePhoneNumbers as a column alias:. This is the result.
