access中时间要用#,不是双引号
select * from kc where rq < #2000-01-01# and rq>#2002-01-01#
不要用between,它的效率泰低
使用# 而不是 ......
查询语句只要这样写,就可以随机取出记录了
SQL="Select top 6 * from Dv_bbs1 where isbest = 1 and layer = 1 order by newID() desc"
在ACCESS里
SELECT top 15 id from tablename order by rnd(id)
SQL Server：
Select TOP N * from TABLE Order By NewID()
Access：
Select TOP N * from TABLE Order By Rnd(ID ......
