取n到m條記錄的語句
1. select top m * from tablename where id not in (select top n id from tablename)
2. select top m * into 臨時表(或表變數) from tablename order by columnname -- 將top m筆插入
set rowcount n
select * from 表變數 order by columnname desc
3. select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
4.如果tablename裡沒有其他identity列,那麼:
select identity(int) id0,* into #temp from tablename
取n到m條的語句為:
select * from #temp where id0 >=n and id0 <= m
如果你在執行select identity(int) id0,* into #temp from tablename這條語句的時候報錯,那是因為你的db中間的select into/bulkcopy屬性沒有開啟要先執行:
exec sp_dboption 你的db名字,'select into/bulkcopy',true
5.如果表裡有identity屬性,那麼簡單:
select * from tablename where identitycol between n and m
6.select top 20 * from a except all
select top 10 * from a --取10到20
