Oracle取TOP N条记录

取出中间5条记录：

SELECT NO FROM (
    SELECT ROW_NUMBER() OVER (ORDER BY NO) RNO, NO FROM ROWNUM_TEST
) WHERE RNO BETWEEN 5 AND 10 ORDER BY NO;

方法2：利用子查询

取出前5条记录：

SELECT NO FROM (
    SELECT NO FROM ROWNUM_TEST  ORDER BY NO
)WHERE ROWNUM <= 5  ORDER BY NO ;

取出中间5条记录：

SELECT NO  FROM (
    SELECT NO, ROWNUM RNO FROM (
        SELECT NO FROM ROWNUM_TEST  ORDER BY NO
    )
) WHERE RNO BETWEEN 5 AND 10  ORDER BY NO;
