PHP: <!--#include file="数据库连接"--> <% "一个从数据库中随机读取纪录的例子 Set Rs1=server.CreateObject ("adodb.recordset") Set Rs=server.CreateObject ("ADODB.RECORDSET") SQL="Select id from Article order by id desc" rs.Open sql,dataconn,1,1 If not rs.EOF then total=rs("id") "取最大的ID rs.Close '定义随机数.. Randomize R=Int((total - 1+ 1) * Rnd + 1) SQL="Select id,content from Article where id="& R rs.Open sql,dataconn,1,1 if not rs.EOF then content=RS("content") content=replace(content,chr(10),"<br>") content=replace(content,chr(13),"<br>") content=replace(content,"<br><br>","<br>") Response.Write content else sql1="select content from Article" rs1.Open sql1,dataconn,1,1 if not rs1.eof then "取第一条纪录作为默认的显示纪录 content=RS1("content") content=replace(content,chr(10),"<br>") content=replace(content,chr(13),"<br>") content=replace(content,"<br><br>","<br>") Response.Write content else "数据库为空 Response.Write "不存在" end if rs1.Close end if Rs.Close end if set Rs=nothing %>
更简单的方法 随机提取10条记录的例子: Sql server: select top 10 * from 表 order by newid() Access: SELECT top 10 * FROM 表 ORDER BY Rnd(id) Rnd(id) 其中的id是自动编号字段,可以利用其他任何数值来完成 比如用姓名字段(UserName) SELECT top 10 * FROM 表 ORDER BY Rnd(len(UserName)) MySql: Select * From 表 Order By rand() Limit 10
