是的,总是这样。您应该能够在需要时使用一组有用的示例数据重新创建生产数据库结构。如果你不这样做，随着时间的推移，保持运行的小改变会被遗忘，然后有一天你会被咬，严重的。这是一种保险，你可能认为你不需要，但当你这样做的那一天，它的价格是它的10倍!

必须阅读将数据库置于版本控制之下。查看K. Scott Allen的系列帖子。

When it comes to version control, the database is often a second or even third-class citizen. From what I've seen, teams that would never think of writing code without version control in a million years-- and rightly so-- can somehow be completely oblivious to the need for version control around the critical databases their applications rely on. I don't know how you can call yourself a software engineer and maintain a straight face when your database isn't under exactly the same rigorous level of source control as the rest of your code. Don't let this happen to you. Get your database under version control.

Here is a sample poor man's solution for a trigger implementing tracking of changes on db objects ( via DDL stateements ) on a sql server 2005 / 2008 database. I contains also a simple sample of how-to enforce the usage of required someValue xml tag in the source code for each sql command ran on the database + the tracking of the current db version and type ( dev , test , qa , fb , prod) One could extend it with additional required attributes such as , etc. The code is rather long - it creates the empty database + the needed tracking table structure + required db functions and the populating trigger all running under a [ga] schema.

作为一种规则，我们将所有的对象代码(存储过程、视图、触发器、函数等)都保存在源代码控制中，因为这些对象都是代码，而且几乎所有其他答案都同意，代码属于某种形式的版本控制系统。

As for CREATE, DROP, ALTER statements, etc. (DDL), we developed and use BuildMaster to manage the deployment of these scripts such that they can be run once and only once against a target database (whether they fail or not). The general idea is that developers will upload change scripts into the system and when it comes time for deployment, only the change scripts that haven't been run against the target environment's database will be run (this is managed very similarly to Autocracy's answer). The reason for this separation of script types lies in that once you manipulate a table's structure, add an index, etc., you effectively cannot undo that without writing a brand new script, or restoring the database - as opposed to the object code where you can simply drop a view or stored procedure then recreate it.

例如，当您将生产数据库恢复到集成环境中时，可以看到一些好处，系统会自动准确地知道哪些脚本没有运行，并将更改新恢复的数据库的表结构，使其与开发相关。

Kira的主要用例之一是通过显式地将数据库外部的模式指定为代码来进行数据库升级。然后，它可以管理数据库，并将其从任何版本升级到任何版本。

RedGate软件提供了一些很棒的工具，可以帮助你对数据库进行版本化。确保让开发者为开发工作构建自己的独立本地数据库，而不是依赖于“开发服务器”，因为“开发服务器”有时可能停机，有时也可能不停机。
