access:
select top* 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* from table1 where 1=1
读取后10条:select top* 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
oracle:
select * from table1 where rownum=10
select top* from table1 where 1=1
