ORDER BY 语句用于根据指定的列对结果集进行排序。
ORDER BY 语句默认按照升序对记录进行排序。
如果您希望按照降序对记录进行排序，可以使用 DESC 关键字。
原始的表 (用在例子中的)：
Orders 表:
Company OrderNumber
IBM 3532
W3School 2356
Apple 4698

row_number() over (partition by col1 order by col2)
表示根据col1分组，在分组内部根据 col2排序
而这个值就表示每组内部排序后的顺序编号（组内连续的唯一的）
表内容如下：
name | seqno | description
A | 1 | test
A | 2 | test
A | 3 | test
A | 4 | test
B | 1 | test
B | 2 | test
B | 3 | test
B | 4 | test
C | 1 | test
C | 2 | test
C | 3 | test
C | 4 | test
我想有一个sql语句，搜索的结果是
A | 1 | test
A | 2 | test
B | 1 | test
B | 2 | test
C | 1 | test
C | 2 | test
实现:
select name,seqno,description
from(select name,seqno,description,row_number()over(partition by name order by seqno)id
from table_name) where id<=3;

Mozilla Firefox web browser has became favorite and default web browser for many systems. However, many websites still work best in Internet Explorer (IE, be it IE6, IE7 or IE8). One such service that works best in Windows Live Hotmail, previously known as MSN Hotmail or just Hotmail. When click on “Open your e-email inbox” button in Windows Live Messenger (MSN Messenger) 2009 or notification pop-up alert on system tray when receiving email in Hotmail inbox, system will open and load Hotmail webmail interface using default web browser, which may not be IE.
When Windows Live Messenger triggers and loads Hotmail in non-IE browser such as Firefox, Google Chrome, Safari or Opera, Hotmail won’t be automatically logged on with the same user account ID that been used to logged into Messenger, as Windows Live Sign-in Helper is only available for Internet Explorer. The add-on provides direct secure route to log into Windows Live ID. As a result, for security reason, user needs to enter user password credentials again to access Hotmail, despite Messenger account is using the same user ID and password.
