---要看你新表存不在存在 如果存在 select * into tb from ta 如果不存在 insert into tb select * from ta
select into '目标表' from '原表'
n-m條記錄 1. select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入 set rowcount n select * from 表变量 order by columnname desc 2. select top n * from (select top m * from tablename order by columnname) a order by columnname desc 3. 如果tablename里没有其他identity列,那么: select identity(int) id0,* into #temp from tablename取n到m条的语句为: select * from #temp where id0 >=n and id0 <= m如果你在执行select identity(int) id0,* into #temp from tablename这条语句的时候报错,那是因为你的DB中间的select into/bulkcopy属性没有打开要先执行: exec sp_dboption 你的DB名字,'select into/bulkcopy',true 4. 如果表里有identity属性,那么简单: select * from tablename where identitycol between n and m 本文来自CSDN博客,转载请标明出处:http://blog.csdn.net/ws_hgo/archive/2008/12/17/3541083.aspx
如果存在 insert into tb select * from ta 如果不存在 select * into tb from ta
如果目标表存在 insert into tb select * from ta 如果目标表不存在 select * into tb from ta
说反了,如果表存在的话,用insert into tb select * from ta 如果不存在,用select * into tb from ta
如果存在
select * into tb from ta
如果不存在
insert into tb select * from ta
1.
select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入
set rowcount n
select * from 表变量 order by columnname desc
2.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
3.
如果tablename里没有其他identity列,那么:
select identity(int) id0,* into #temp from tablename取n到m条的语句为:
select * from #temp where id0 >=n and id0 <= m如果你在执行select identity(int) id0,* into #temp from tablename这条语句的时候报错,那是因为你的DB中间的select into/bulkcopy属性没有打开要先执行:
exec sp_dboption 你的DB名字,'select into/bulkcopy',true
4.
如果表里有identity属性,那么简单:
select * from tablename where identitycol between n and m 本文来自CSDN博客,转载请标明出处:http://blog.csdn.net/ws_hgo/archive/2008/12/17/3541083.aspx
insert into tb select * from ta
如果不存在
select * into tb from ta
insert into tb select * from ta
如果目标表不存在
select * into tb from ta
如果不存在,用select * into tb from ta
