在ASP页面进行参数化查新一例

例子很明了，一看就明白。代码如下：

VBScript 代码

 也可以写出下面的格式：

VBScript 代码

Dim rs, cmd, cn
Set cmd = Server.CreateObject( " ADODB.Command " )
Set cn = Server.CreateObject( " ADODB.Connection " )
' 此处连接的是SQL Server 2008数据库，其他数据库修改连接字符串。
cn.Open " Provider=SQLNCLI10;Server=(local);Database=数据库名称;Uid=数据库登录名;Pwd=密码; "
With cmd
    .ActiveConnection = cn
    .CommandType = adCmdText
    .CommandText = " Select * From BaseObject Where parentname LIKE ? And contentclass=? "
    .Prepared = True
    .Parameters( 0 ).Value = " %/ItemImage/% "
    .Parameters( 1 ).Value = " urn:schemas- mengxianhui -com-cn:basedocument "
     Set rs = .Execute
End With
While Not rs.EOF
  Response.Write " <li> " & rs( " displayname " )
  rs.MoveNext
Wend
