access:
select top (10) * from table1 where 1=1

db2:
select column from table where 1=1 fetch first 10 rows only

mysql:
select * from table1 where 1=1 limit 10

sql server:
读取前10条:select top (10) * from table1 where 1=1
读取后10条:select top (10) * from table1 order by id desc
在sqlserver里面,如何读取按照某个排序,第5到10这五个记录
select top 6 * from table where id not in(select top 4 id from table)

oracle:
select * from table1 where rownum<=10
