Using an Updategram in a Sample ASP Application (SQLXML 4.0)
This Active Server Pages (ASP) application allows you to update customer information in the Person.Contact table in the AdventureWorks sample database in Microsoft SQL Server. The application does the following:
Asks the user to enter a contact ID.
Uses this customer ID value to execute a template to retrieve contact information from the Person.Contact table.
Displays this information by using an HTML form.
The user can then update contact information but not the contact ID (because the ContactID is the primary key). After the user submits the information, an updategram is executed and all the form parameters are passed to the updategram.
The following template is the first template (GetContact.xml). Save this template in the directory that is associated with the virtual name of template type.
<root xmlns:sql="urn:schemas-microsoft-com:xml-sql">
<sql:header>
<sql:param name="cid"></sql:param>
</sql:header>
<sql:query>
SELECT *
FROM Person.Contact
WHERE ContactID=@cid
FOR XML AUTO
</sql:query>
</root>
The following template is the second template (UpdateContact.xml). Save this template in the directory that is associated with the virtual name of template type.
<ROOT xmlns:updg="urn:schemas-microsoft-com:xml-updategram">
<updg:header>
<updg:param name="cid"/>
<updg:param name="title" />
<updg:param name="firstname" />
<updg:param name="lastname" />
<updg:param name="emailaddress" />
<updg:param name="phone" />
</updg:header>
<updg:sync >
<updg:before>
<Person.Contact ContactID="$cid" />
</updg:before>
<updg:after>
<Person.Contact ContactID="$cid"
Title="$title"
FirstName="$firstname"
LastName="$lastname"
EmailAddress="$emailaddress"
Phone="$phone"/>
</updg:after>
</updg:sync>
</ROOT>
The following code is the ASP application (SampleASP.asp). Save it in the directory that is associated with a virtual root that you create by using the Internet Services Manager utility. (This virtual root is not created by using the IIS Virtual Directory Management for SQL Server utility because IIS Virtual Directory Management for SQL Server cannot access or identify ASP applications.).
Note
In the code, you must replace "ServerName" with the name of the server running Microsoft Internet Information Services (IIS).
