一些不长见的ASP调用存储过程的技巧

 2004-05-06 10:26:44 来源:WEB开发网   
核心提示:1、最简单的如下 Dim objConn Set objConn = Server.CreateObject("ADOBD.Connection") objConn.Open application("Connection_String") 'Call the st

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
