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

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

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

order by newID() 就是随机显示，不信你试试

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
%>
