本文介绍了一种使用SQL查询来统计指定日期范围内每个小时的交易总量的方法。通过GROUP BY和DATEPART函数组合使用，可以方便地按小时聚合数据。
select COUNT(*) AS '交易量',DATEPART(hh,CDate) as '小时' 
from PG_Txn 
 WHERE
 CDate>=convert(varchar(10),GETDATE(),120)
 and CDate <convert(varchar(10),dateadd(day,1,getdate()),120)

 group by DATEPART(HH,CDate)：

前言：学以致用，学习重要，输出更重要！在学习SQL的时候，一直有个疑问，用EXCEL就好了啊，SQL学起来干嘛用，直到SQL基础部分学完了，开始做练习，才发现二者的不同。两个作用差不多，EXCEL处理小数据，SQL处理大数据，且数据来源也不一样。两个可以结合来用，可以更省时省力，各有优缺点，下面就黑五数据用两个方法对比分析体验一下。相关信息：美国圣诞节大采购一般是从感恩节之后开始的。感恩节是每年1...

[ASP.NET] 事务（Transaction）是并发使用及C#上程序应用

事务（Transaction）是并发控制的单位，是用户定义的一个操作序列。这些操作要么都做，要么都不做，是一个不可分割的工作单位。 通过事务，SQL Server能将逻辑相关的一组操作绑定在一起，以便服务器保持数据的完整性。 在sql server+ .net 开发环境下，有两种方法能够完成事务的操作，保持数据库的数据完整性； 一个就是用sql存储过程，另一个就是在ADO.NET中一种简单的
