在我工作的地方，sproc的最大优势是我们有更少的代码移植到VB。NET(来自VB6)。而且它的代码更少，因为我们对所有的查询都使用了spprocs。

当我们需要更新查询而不是更新VB代码，重新编译并在所有计算机上重新安装它时，它也有很大的帮助。

SQL存储过程不会提高查询的性能

我喜欢存储过程，不知道有多少次我能够使用存储过程对应用程序进行更改，而不会对应用程序产生任何停机时间。

作为Transact SQL的忠实粉丝，调优大型查询已被证明对我非常有用。我已经6年没有写过任何内联SQL了!

安全?为什么scprocs会更安全?

正如Komradekatz所建议的，您可以禁止访问表(对于连接到DB的用户名/密码组合)，而只允许SP访问。这样，如果有人获得了数据库的用户名和密码，他们可以执行SP，但不能访问表或数据库的任何其他部分。

(当然，执行scproc可以给他们所有他们需要的数据，但这将取决于可用的scproc。给他们访问表的权限，他们就能访问所有东西。)

Definitely easier to maintain if you put it in a stored procedure. If there's difficult logic involved that will potentially change in the future it is definitely a good idea to put it in the database when you have multiple clients connecting. For example I'm working on an application right now that has an end user web interface and an administrative desktop application, both of which share a database (obviously) and I'm trying to keep as much logic on the database as possible. This is a perfect example of the DRY principle.

I'm firmly on the side of stored procs assuming you don't cheat and use dynamic SQL in the stored proc. First, using stored procs allows the dba to set permissions at the stored proc level and not the table level. This is critical not only to combating SQL injection attacts but towards preventing insiders from directly accessing the database and changing things. This is a way to help prevent fraud. No database that contains personal information (SSNs, Credit card numbers, etc) or that in anyway creates financial transactions should ever be accessed except through strored procedures. If you use any other method you are leaving your database wide open for individuals in the company to create fake financial transactions or steal data that can be used for identity theft.

存储的proc也比从应用程序发送的SQL更容易维护和性能调优。它们还允许dba查看数据库结构更改对数据访问方式的影响。我从未遇到过允许动态访问数据库的优秀dba。
