各种数据库取前10行记录
access:
select top (10) * from table1 where 1=1
db2:
select column from table where 1=1 fetch first 10 rows only
取第3行到第5行的记录
select * from (select row_number() over() as row from table) as temp where row>=3 and row<=5
mysql:
select * from table1 where 1=1 limit 10
sql server:
前10条:select top (10) * from table1 where 1=1
后10条 select top (10) * from table1 order by id desc
在sqlserver,如何读取按照某个排序,第5到10行这个记录
select top 6 * from table where id not in(select top 4 id from table)
oracle:
select * from table1 where rownum<=10
取中间记录:60~100
select * from (select rownum r,a.* from table a where rownum <= 100) where r >= 60;
