用iBATIS.NET读取单条记录，并对这条记录进行修改。
修改Maps/Customers.xml文件，在statements标记中添加下面代码：

<update id="UpdateCustomer" parameterClass="Customers">
update Customers set
CompanyName=#CompanyName#,
ContactName=#ContactName#,
ContactTitle=#ContactTitle#,
Address=#Address#,
City=#City#,
Region=#Region#,
PostalCode=#PostalCode#,
Country=#Country#,
Phone=#Phone#,
Fax=#Fax#
where CustomerID=#CustomerID#
</update>

<statement id="SelectCustomer" parameterClass="string" resultClass="Customers">
select
CustomerID as CustomerID,
CompanyName as CompanyName,
ContactName as ContactName,
ContactTitle as ContactTitle,
Address as Address,
City as City,
Region as Region,
PostalCode as PostalCode,
Country as Country,

from Customers where CustomerID=#value#
</statement>
