我们有15个产品,每天在主页要它随机的显示三条?你说这样怎么编?

[mustapha]

set top 3 * from tabel order by newID()

[liyefei]

老大我说的是随机显示三条记录啊,有高招么?

[Jaron]

select top 3 * from [tabel] order by newid() 从表中随机抽取三条记录.

[aseadi]

随机id

[Newrocky]

随机抽取3条出来以后，再显示
'建立DCNDB连接
RS.OPEN "SELECT top 3 * from tabel order by newID()",DCNDB,1,1
DO WHILE NOT RS.EOF
response.write rs(0)
rs.movenext
loop

[aseadi]

<%radonmize
i=(15-1+1)*rnd+1
sql="select top 3 * from table where id="&i
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,1,1
do while not rs.eof
response.write rs("news")
rs.movenext
loop%>记得关闭数据rs和数据库哦!!呵呵!!

[bybee]

sql server
select top 3 * from tabel order by newID()
access
select top 3 * from tabel order by rnd(id)

[aseadi]

<%
randomize
for i=1 to 3
j=int((6-1+1)*rnd+1)
sql="select * from body where bodyid="&j
set rs=server.CreateObject("adodb.recordset")
rs.open sql,conn,1,1
response.Write(rs("body"))&"<br>"
rs.close
next
set conn=nothing
%>

[mustapha]

order by newID() 就是随机显示，不信你试试

[叮咚叮咚叮叮咚]

set top 3 * from tabel order by newID()
这个就是啊

[lonaerd]

dim dst1(2)

dst1(0)=cint(rnd*15)
dst1(1)=cint(rnd*15)
dst1(2)=cint(rnd*15)

然后判断这三个数是否相等，如果相等再决定加1或减1，最终就是得到三个0-14并且互不相等的数。
得到三个数字后接下来我就不多说了

[叮咚叮咚叮叮咚]

randomize
RNumber=int(rnd*15)
RNumber2=int(rnd*15)
RNumber3=int(rnd*15)
SQL = "SELECT * FROM Customers WHERE ID in (" & RNumber & ", " & RNumber2 & " ," & RNumber3&")"

[jianxuehua]

最简单的：
sql server
select top 3 * from tabel order by newID()
access
select top 3 * from tabel order by rnd(id)
