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!

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

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.

你的编程语言和应用程序框架可能是:

高级的，特别是与SQL相比 易于通过自动化流程进行版本和部署，特别是与SQL相比

如果这两个条件是两个，则跳过存储过程。

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。

Something that I haven't seen mentioned thus far: the people who know the database best aren't always the people that write the application code. Stored procedures give the database folks a way to interface with programmers that don't really want to learn that much about SQL. Large--and especially legacy--databases aren't the easiest things to completely understand, so programmers might just prefer a simple interface that gives them what they need: let the DBAs figure out how to join the 17 tables to make that happen.

话虽如此，用于编写存储过程的语言(PL/SQL就是一个臭名昭著的例子)是相当残酷的。它们通常不提供您在当今流行的命令式语言、OOP或函数式语言中看到的任何细节。认为COBOL。

因此，请坚持使用仅抽象了关系细节的存储过程，而不是那些包含业务逻辑的存储过程。
