ASP调用存储过程的技巧

答案：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.asp001.net', 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
