一些不长见的ASP调用存储过程的技巧

新客网 XKER.COM 2003-04-17 来源：收藏本文

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
