Question

当我尝试从经典ASP调用MySql存储过程时，我收到此错误：

例程spAddContactUsEmail的OUT或INOUT参数5不是BEFORE触发器中的变量或NEW伪变量

这是SP（我可以从Mysql工作台成功调用）：

CREATE DEFINER=`root`@`localhost` PROCEDURE `spAddContactUsEmail`(
    In vcName varchar(50),
    In vcPhone varchar(50),
    In vcEmail varchar(50),
    In txtComments text,
    Out intNewID int
)
BEGIN

    Insert Into contact_us (`Name`, Phone, Email, Comments, DateCreated) 
    Values (vcName, vcPhone, vcEmail, txtComments, now());

    Set intNewID = Last_Insert_ID();

END

这是ASP代码：

Dim con
Dim cmd

Set con = Server.CreateObject("ADODB.Connection")
con.Open "connection string" 

Set cmd = Server.CreateObject("ADODB.Command")
cmd.ActiveConnection = con
cmd.CommandType = adCmdStoredProc
cmd.CommandText = "spAddContactUsEmail"

cmd.Parameters.Append cmd.CreateParameter("vcName", adVarChar, adParamInput, 50, "John Doe")
cmd.Parameters.Append cmd.CreateParameter("vcPhone", adVarChar, adParamInput, 50, "333-4444")
cmd.Parameters.Append cmd.CreateParameter("vcEmail", adVarChar, adParamInput, 50, "test@yahoo.com")
cmd.Parameters.Append cmd.CreateParameter("txtComments", adLongVarChar, adParamInput, Len("hey"), "hey")

cmd.Parameters.Append cmd.CreateParameter("intNewID", adInteger, adParamReturnValue)

cmd.Execute

cmd.Execute行发生错误。提前谢谢。

Answer 1

将adParamReturnValue更改为adParamOutput：

<%
    cmd.Parameters.Append cmd.CreateParameter("intNewID", adInteger, adParamOutput, 4)
%>

从ASP调用Mysql SP会产生错误
