db2, oracle和sqlserver,mysql取前几行的各自独自语法

星期六, 五月 16th, 2009 | Database, JAVA-and-J2EE | 2 Comments

常用的四种数据库的取前几行的sql语句如下: 以前比较不熟悉的是db2,现在天天用,也感觉不错了
db2:
SELECT * ROW_NUMBER() OVER(ORDER BY COL1 DESC) AS ROWNUM WHERE ROWNUM<=10 或者 select * from tab fetch first 10 rows only oracle: select * from tab where rownum <=10 sqlserver: select top 10 * from tab mysql: select * from tab limit 10
