ASP调用sql server存储过程的技巧

yibin 2015-02-09 建站源码 647

在asp程序中使用sql server存储过程是常见的事,主要的作用是提高程序运行的时间,这里介绍一下调用不同类型的存储过程的方法。    一、最简单的调用
    <%
    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
    二、带参数的一种调用
    <%
    objConn.Execute "exec sp_AddHit,'http://www.aspbc.com', 1"
    %>
    注意分割参数,该方法也不返回记录
    三、带返回记录集的
    <%
    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
    %>
    四、带参数和返回记录集的
    <%
    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
    %>
    五、存储过程代码
    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
