ASP脚本里加事务
joyous jeny · 2008-06-30 · via 博客园 - joyous jeny
 

事务声明:将某个页声明为事务性,可在页首添加 @TRANSACTION 指令:

<%@ TRANSACTION = value %>

value 参数可以是下列之一:

意义

Requires_New

启动一个新的事务。

Required

启动一个新的事务。

Supported

不启动事务。

Not_Supported

不启动事务。

@TRANSACTION 指令必须在一页中的第一行,否则将产生错误。不要将应用程序的 Global.asa 文件声明为事务性。

事务终止:ObjectContext.SetAbort显式地声明终止一个事务。

事务的响应:使用OnTransactionCommitOnTransactionAbort事件来编写对用户的不同响应。

<%@ TRANSACTION = Required %>

<%

'Buffer output so that different pages can be displayed.

Response.Buffer = True

%>

<HTML>

<BODY>

<H1>Welcome to the online banking service</H1>

<%

Set BankAction = Server.CreateObject("MyExample.BankComponent")

BankAction.Deposit(Request("AcctNum"))

%>

<P>Thank you. Your transaction is being processed.</P>

</BODY>

</HTML>

<%

' Display this page if the transaction succeeds.

Sub OnTransactionCommit()

 Response.Write "<HTML>"

 Response.Write "<BODY>"

 Response.Write "Thank you. Your account has been credited."

 Response.Write "</BODY>"

 Response.Write "</HTML>"

 Response.Flush()

end sub

%>

<%

' Display this page if the transaction fails.

Sub OnTransactionAbort()

 Response.Clear()

 Response.Write "<HTML>"

 Response.Write "<BODY>"

 Response.Write "We are unable to complete your transaction."

 Response.Write "</BODY>"

 Response.Write "</HTML>"

 Response.Flush()

End sub

%>
