将Session值储存于SQL Server中
一般情况下，我们喜欢使用Session储存我们的变量。Asp.Net提供了下面一些方法储存Session的值：InProc
State Server
SQL Server
“InProc”表示我们使用传统ASP一样的方法储存Session的值，而且“State Server”则表示使用另外一台主机来储存Session的值。当然我们也能使用SQL Server储存值，我们这篇文章就专门用于讲解这种方法。
运行InstallSqlState.sql文件
首先需要在WinntMicrosoft.Net中找到InstallSqlState.sql文件，然后在SQL Server 中执行它。在我的机器中，它存在于E:WINNTMicrosoft.NETFrameworkv1.0.2914目录中。这个文件是微软自己提供的，里面有很全的SQL语句，大家放心使用。下图就是生成的数据表。
修改你的web.config文件，指定Session的mode为SQL Server
将web.config的sessionState部分改成：
WIN2000;userid=
sa;password=" cookieless= "false"timeout=
"20" />
创建Asp.Net Web Forms
下面就建立一个测试的ASP.net程序，使用Session程序这里就不用多说了，下面是我的程序的截图。这个程序只是简单的储存一个字符串数据于Session中，然后再显示这个数据在Label控件中。
现在所有的Session变量都储存在数据表中，而不是内存中了。你可打开ASPStateTempSessions表来查看这些Session数据了。
删除这些数据库和表
如果你不喜欢这个数据储存方式，看得实在是不爽，那么你可以把这些表和数据库完全删除掉。这个也不要担心这种删除会影响数据库（因为害怕误删除一些数据），因为微软同样也得供给你们一个删除SQL 文件，名叫UnintallSQLState.sql。它与IntallSQLState.sql一样放在.Net的Config目录中。
