ASP Classic VBscript 参数化 SQL 查询? [英] ASP Classic VBscript Parameterized SQL Query?

问题描述

第一次发帖，但感谢您到目前为止从该网站获得的所有帮助.

First post but thank you for all the help I've gotten from this site so far.

我正在尝试参数化 SQL 查询:

I'm trying to parameterize an SQL query:

query_url = Request.QueryString("ID")

Set rs = Server.CreateObject("ADODB.Recordset")

Set cmd = server.createobject("ADODB.Command")

cmd.ActiveConnection = Internet_String
cmd.CommandType = adCmdText
cmd.CommandText = "SELECT NAME FROM OWNER.TABLE WHERE ID = " + "?" + ""

Set param = cmd.CreateParameter(, , ,200 , Replace(query_url, "'", "''"))

cmd.Parameters.Append param

Set rs = cmd.Execute()

所以如果我使用(无参数):

So if I use (no parameters):

SELECT NAME FROM OWNER.TABLE WHERE ID = " + Replace(query_url, "'", "''") + ""

它工作正常，所以我知道我的数据库连接和 query_url 工作正常.我在参数化查询中的 SQL 语句有问题吗?我已经尝试了很多不同的方法.

It works fine, so I know my DB connection and query_url are working. Is something wrong with my SQL statement in the parameterized query? I've tried it so many different ways.

当我在 Dreamweaver 中运行参数化查询时，页面不会随时加载，只会无限旋转，我假设它没有从数据库中得到响应.

When I run my parameterized query in Dreamweaver the page will not load anytime, just spins infinitely, I'm assuming it's not getting a response back from the DB.

谢谢！

编辑

好的，谢谢你到目前为止的帮助，我越来越近了.页面现在加载，但字段仍然是空白的，这是我到目前为止所得到的:

Alright thanks for the help so far, I'm getting closer. The page loads now but the fields are still blank, heres what I've got so far:

Set rs = Server.CreateObject("ADODB.Recordset")

Set cmd = server.createobject("ADODB.Command")

cmd.ActiveConnection = internet_string    
cmd.CommandType = adCmdText

cmd.CommandText = "SELECT NAME FROM OWNER.TABLE WHERE ID = @param"

Set param = cmd.CreateParameter("@param", , ,200 , query_url)

cmd.Parameters.Append param

response.Write(param)

Set rs = cmd.Execute()

这是我引用数据的方式:

Here's how I'm referencing the data:

<strong>Name: <%=(rs.Fields.Item("NAME").Value)%></strong>

有什么想法吗?

推荐答案

使用命名占位符；

cmd.CommandText = "SELECT NAME FROM OWNER.TABLE WHERE ID = @ID"

然后提供它的值

Set param = cmd.CreateParameter("@ID", , ,200, Replace(query_url, "'", "''"))

仅供参考，您不需要在参数化查询中转义 '

FYI you do not need to escape ' in an parameterized query
