为什么程序中捕获不到return -1这个值呢？
logins是int型，我有意让它+a,也就是想让它报错，返回-1，但是程序中捕获的却是空值
如果改成+1可以正常返回0或者1
DIM MyComm : Set MyComm = Server.CreateObject("ADODB.Command")
with MyComm
.ActiveConnection = Conn
.CommandText = "zd_kjjLogin"
.CommandType = 4
.Prepared = true
.Parameters.append .CreateParameter("RETURN",2,4)
.Parameters.append .CreateParameter("@ID",3,2,4)
.Parameters.append .CreateParameter("@userClass",200,2,20)
.Parameters.append .CreateParameter("@department",200,2,20)
.Parameters.append .CreateParameter("@purview",200,2,20)
.Parameters.append .CreateParameter("@UserName",200,1,20,userName)
.Parameters.append .CreateParameter("@Password",200,1,20,passWord)
.Parameters.append .CreateParameter("@ip",200,1,20,ip)
.Execute
end with
response.write MyComm(0)
这是调用程序
