我参加的Microsoft TechEd安全会议的建议之一是，通过存储过程进行所有调用，并拒绝直接访问表。这种方法被宣传为提供额外的安全性。我不确定仅仅为了安全性是否值得这样做，但如果您已经在使用存储过程，那么这样做也无妨。

CON

我发现在存储过程中进行大量的处理会使您的DB服务器在扩展您的行为时成为一个单一的不灵活点。

然而，如果您有多个服务器运行您的代码，那么在您的程序中进行所有这些处理而不是sql-server，可能会允许您进行更多的扩展。当然，这并不适用于只进行正常获取或更新的存储procs，而是适用于执行更多处理(如在数据集上循环)的存储procs。

PROS

Performance for what it may be worth (avoids query parsing by DB driver / plan recreation etc) Data manipulation is not embedded in the C/C++/C# code which means I have less low level code to look through. SQL is less verbose and easier to look through when listed separately. Due to the separation folks are able to find and reuse SQL code much easier. Its easier to change things when schema changes - you just have to give the same output to the code and it will work just fine Easier to port to a different database. I can list individual permissions on my stored procedures and control access at that level too. I can profile my data query/ persistence code separate from my data transformation code. I can implement changeable conditions in my stored procedure and it would be easy to customize at a customer site. It becomes easier to use some automated tools to convert my schema and statements together rather than when it is embedded inside my code where I would have to hunt them down. Ensuring best practices for data access is easier when you have all your data access code inside a single file - I can check for queries that access the non performant table or that which uses a higher level of serialization or select *'s in the code etc. It becomes easier to find schema changes / data manipulation logic changes when all of it is listed in one file. It becomes easier to do search and replace edits on SQL when they are in the same place e.g. change / add transaction isolation statements for all stored procs. I and the DBA guy find that having a separate SQL file is easier / convenient when the DBA has to review my SQL stuff. Lastly you don't have to worry about SQL injection attacks because some lazy member of your team did not use parametrized queries when using embedded sqls.

我还没有找到一种在源代码控制中轻松维护存储过程的好方法，使其与代码库一样无缝。这是不会发生的。仅这一点就使得在代码中添加SQL对我来说是值得的。在现代系统中，性能差异可以忽略不计。

我们在Oracle数据库中使用存储过程。我们也使用Subversion。所有存储过程都被创建为.pkb & .pks文件并保存在Subversion中。我以前做过内嵌SQL，这很痛苦!我更喜欢我们在这里的方式。创建和测试新的存储过程比在代码中执行要容易得多。

存储过程的性能优势通常可以忽略不计。

存储过程的更多优点:

防止反向工程(当然，如果使用加密创建的话) 更好地集中数据库访问 能够透明地更改数据模型(无需部署新客户端);当多个程序访问相同的数据模型时尤其方便

存储过程。

如果出现错误或者逻辑稍有变化，您不必重新编译项目。此外，它允许从不同的来源访问，而不仅仅是在项目中编写查询的一个地方。

我不认为维护存储过程更难，你不应该直接在数据库中编写它们，而应该先在单独的文件中编写，然后你可以在任何你需要设置的DB上运行它们。
