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)
