一些值得记住的SQL

各种不同的数据库查询前N条记录，都不一样，现在总结了一下，列了出来：
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 NGOSELECT * FROM TABLE1
6. MYSQL SQLLITE
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


offset 偏移量,比如要查第10条到第15条 就是一下SQL.

SELECT * FROM TABLE order by id asc limit 5 offset 10;
