不同数据库中查询前几条记录的用法

mysql:

select * from table LIMIT 5,10; #返回第6-15行数据

select * from table LIMIT 5; #返回前5行

select * from table LIMIT 0,5; #返回前5行

 

1. orACLE 
Select * FROM TABLE1 Where ROWNUM<=N 


2. INFORMIX 
Select FIRST N * FROM TABLE1 


3. DB2 
Select * ROW_NUMBER() OVER(ORDER BY COL1 DESC) AS ROWNUM Where ROWNUM<=N 
或者
Select COLUMN FROM TABLE FETCH FIRST N ROWS ONLY


4. SQL SERVER 
Select TOP N * FROM TABLE1 


5. SYBASE 
SET ROWCOUNT N 
GO
Select * FROM TABLE1 


6. MYSQL 
Select * FROM TABLE1 LIMIT N 


7. FOXPRO 
Select * TOP N FROM TABLE orDER BY COLUMN 

 

8.postgres查询前几条记录SQL 
Select * FROM TABLE LIMIT  n

 

 

=================================================================================================

如在ms sqlserver 用此语句：
select top 2 * from test01 就会只显示前2条记录，

 

MYSQL/PostgreSQL
select * from your_table where .... limit 2;
//使用limit就可以了.

 

Oracle的语句:
select * from (select rownum r ,* from test) tt
where tt.r > 50 and tt.r <= 100; (最好用PLSQL游标来解决)

 

 

DB2中：
select * from payment fetch first 5 row only --查前5条记录
