最简单查询带分页功能的代码

类别：软件工程点击：0 评论：0 推荐：

最简单的查询带分页功能的页面(跳转分页时查询条件不丢失),希望对大家有所帮助.
先建立一个Access的数据库Db1.mdb,里面有一个数据表Dicky,共4个字段:
字段名数据类型
ID         AutoNumber
Name    Text
Sex        Text
Age        Number
QQ        Number
建立完库后请自行添加几条数据作为测试.

Page.asp代码如下:
<html>
<head>
<title>分页测试</title>
<script language="javascript">

</script>
</head>
<body>
<table align=center>
<form name=form1 method=post>
<input type=hidden name=GotoPage>
<tr><td>
<input type=checkbox name=Sex value="男"<%If Instr(Replace(Request("Sex")," ",""),"男") <> 0 Then Response.Write " checked"%>>男<input type=checkbox name=Sex value="女"<%If Instr(Replace(Request("Sex")," ",""),"女") <> 0 Then Response.Write " checked"%>>女
<input type=submit name=search value=搜索>
</td>
</tr>
</form>
</table>
<table width=100% align=center>

Set Conn = Server.CreateObject("ADODB.Connection")

Conn.Open ConnStr
If Trim(Request("Sex")) = "" Or Trim(Request("Sex")) = "男, 女" Then
Sql = "Select * From Dicky"
Else
Sql = "Select * From Dicky Where Sex='"&Trim(Request("Sex"))&"'"
End If
'Response.Write Sql
