1、最简单的如下
           Dim objConn
    Set objConn = Server.CreateObject("ADOBD.Connection")
    objConn.Open Application("Connection_String")
    'Call the stored procedure to increment a counter on the page
    objConn.Execute "exec sp_AddHit"
没有参数，没有返回，没有错误处理，就是这个了
2、带参数的一种调用
objConn.Execute "exec sp_AddHit 'http://www.aspalliance.com', 1"
请注意分割参数，该方法也不返回记录

3、返回记录的
          Dim objConn
    Dim objRs
    Set objConn = Server.CreateObject("ADOBD.Connection")
    Set objRs = Server.CreateObject("ADOBD.Recordset")
    objConn.Open Application("Connection_String")
    'Call the stored procedure to increment a counter on the page
    objRs.Open objConn, "exec sp_ListArticles '1/15/2001'"
    'Loop through recordset and display each article
4、……
          Dim objConn
          Dim objCmd

'Instantiate objects
Set objConn        = Server.CreateObject("ADODB.Connection")
set objCmd        = Server.CreateObject("ADODB.Command")
conn.Open Application("ConnectionString")

With objCmd
    .ActiveConnection = conn 'You can also just specify a connection string here
    .CommandText = "sp_InsertArticle"
    .CommandType = adCmdStoredProc 'Requires the adovbs.inc file or typelib meta tag

    'Add Input Parameters
    .Parameters.Append .CreateParameter("@columnist_id", adDouble, adParamInput, , columnist_id)
    .Parameters.Append .CreateParameter("@url", adVarChar, adParamInput, 255, url)
    .Parameters.Append .CreateParameter("@title", adVarChar, adParamInput, 99, url)
    .Parameters.Append .CreateParameter("@description", adLongVarChar, _
        adParamInput, 2147483647, description)

    'Add Output Parameters
    .Parameters.Append .CreateParameter("@link_id", adInteger, adParamOutput, , 0)

    'Execute the function
    'If not returning a recordset, use the adExecuteNoRecords parameter option
    .Execute, , adExecuteNoRecords
    link_id = .Parameters("@link_id")
End With

5、存储过程的代码
Create PROCEDURE dbo.sp_InsertArticle
(
    @columnist_id int,
    @url varchar(255),
    @title varchar(99),
    @description text
       @link_id int OUTPUT
)
AS
BEGIN
    INSERT INTO dbo.t_link    (columnist_id,url,title,description)
    VALUES (@columnist_id,@url,@title,@description)

    SELECT @link_id = @@IDENTITY
END
