程序移动位置后，无法访问数据库

答案：
这种错误首先在ODBC，如果ODBC数据源设置正确，那么需要注意ASP中打开数据库的命令：Conn.Open 的参数是否正确。如果正确，则需要注意是否使用了global.asa文件，该文件是ASP连接数据库的配置文件，该文件内容如下： 
<SCRIPT LANGUAGE="VBScript" RUNAT="Server"> 
'You can add special event handlers in this file that will get run automatically when special Active Server Pages events 
'occur. To create these handlers, just create a subroutine with a name from the list below that corresponds to the event 
'you want to use. For example, to create an event handler for Session_OnStart, you would put the following code into this 
'file (without the comments): 
'EventName Description 
'Session_OnStart Runs the first time a user runs any page in your application 
'Session_OnEnd Runs when a user's session times out or quits your application 
'Application_OnStart Runs once when the first page of your application is run for the first time by any user 
'Application_OnEnd Runs once when the web server shuts down 
</SCRIPT> 
<SCRIPT LANGUAGE=VBScript RUNAT=Server> 
Sub Session_OnStart 
'==Visual InterDev Generated - DataConnection startspan== 
'--Project Data Connection 
Session("Customers_ConnectionString")="DRIVER={SQL Server};SERVER=(local);UID=sa;PWD=;APP=Microsoft(R)Developer Studio;WSID=GREGLEAK;DATABASE=Customers" 
Session("Customers_ConnectionTimeout") = 15 
Session("Customers_CommandTimeout") = 30 
Session("Customers_RuntimeUserName") = "sa" 
Session("Customers_RuntimePassword") = "" 
'==Visual InterDev Generated - DataConnection endspan== 
End Sub 
</SCRIPT> 
要注意其中的DSN，其中SERVER后一定是数据库服务器名称，如果该处不正确，需要改正。另外是UID和PWD是否正确；还有，如果OPEN命令使用了SESSION，则需要注意 
Session("Customers_RuntimeUserName") = "sa" 
Session("Customers_RuntimePassword") = "" 
是否正确。
