取表中第n条或取n到m条纪录
SQL查找第n条记录的方法:
select top 1 * from table where id not in (select top n-1 id from table) temptable0
SQL查找第n条开始的m条记录的方法:
select top m * from table where id not in (select top n-1 id from table) temptable0)
(注:表中必须有一个唯一值字段才可适用此方法。)
四种方法取表里n到m条纪录:
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
