哪位大神告诉一下vb6.0怎么调用带2个参数的存储过程,有简单的例子最好。谢谢! 100

Dim CmdSP
Dim adoRS
Dim adCmdSPStoredProc
Dim adParamReturnValue
Dim adParaminput
Dim adParamOutput
Dim adInteger
Dim iVal
Dim oVal
Dim adoField
Dim adVarChar
'这些值在 VB 中是预定义常量,可以直接调用,但在 VBScript 中没有预定义
adCmdSPStoredProc = 4
adParamReturnValue = 4
adParaminput = 1
adParamOutput = 2
adInteger = 3
adVarChar = 200
iVal = 5
oVal = 3
'建一个command对象
set CmdSP = Server.CreateObject("ADODB.Command")
'建立连结
CmdSP.ActiveConnection = "Driver={SQL Server};server=(local);Uid=sa;Pwd=sa;Database=Pubs"
'定义command 对象调用名称
CmdSP.CommandText = "sp_PubsTest"
'设置command调用类型是存储过程 (adCmdSPStoredProc = 4)
CmdSP.CommandType = adCmdSPStoredProc
'往command 对象中加参数
'定义存储过程有直接返回值,并且是个整数,省缺值是4
CmdSP.Parameters.Append CmdSP.CreateParameter("RETURN_VALUE", adInteger, adParamReturnValue, 4)
'定义一个字符型输入参数
CmdSP.Parameters.Append CmdSP.CreateParameter("@au_lname", adVarChar, adParaminput, 20, "M")
'定义一个整型输入参数
CmdSP.Parameters.Append CmdSP.CreateParameter("@intID", adInteger, adParamInput, , iVal)
'定义一个整型输出参数
CmdSP.Parameters.Append CmdSP.CreateParameter("@intIDOut", adInteger, adParamOutput, oVal)
'运行存储过程,并得到返回记录集
Set adoRS = CmdSP.Execute
'把每个记录打印出来,其中的字段是虚拟的,可以不用管
While Not adoRS.EOF
for each adoField in adoRS.Fields
Response.Write adoField.Name & "=" & adoField.Value & "<br>" & vbCRLF
Next
Response.Write "<br>"
adoRS.MoveNext
Wend
'打印两个输出值:
Response.Write "<p>@intIDOut = “ & CmdSP.Parameters("@intIDOut").Value & "</p>"
Response.Write "<p>Return value = " & CmdSP.Parameters("RETURN_VALUE").Value & "</p>"
'大扫除
Set adoRS = nothing
Set CmdSP.ActiveConnection = nothing
Set CmdSP = nothing
以上代码仅供参考
其实核心的就是如何获得存储过程的返回值
追问
还是没看明白呢,能不能把我发的那个存储过程 做一个呢?我照着样子写试试?麻烦啦。。。
