現(xiàn)在用oracle ，PL Sql中順手寫了個(gè) select top 1 *

Select Top在不同數(shù)據(jù)庫中的使用用法：
1. Oracle數(shù)據(jù)庫
SELECT * FROM TABLE1 WHERE ROWNUM<=N
|
2. Infomix數(shù)據(jù)庫
SELECT FIRST N * FROM TABLE1
|
3. DB2數(shù)據(jù)庫
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數(shù)據(jù)庫
SELECT TOP N * FROM TABLE1
|
5. Sybase數(shù)據(jù)庫
SET ROWCOUNT N
GO
SELECT * FROM TABLE1
|
6. MySQL數(shù)據(jù)庫
SELECT * FROM TABLE1 LIMIT N
|
7. FoxPro數(shù)據(jù)庫
SELECT * TOP N FROM TABLE ORDER BY COLUMN
