每个数据库都应该在源代码控制下。目前缺少的是一种工具，可以自动将所有数据库对象(以及“配置数据”)脚本化为文件，然后将其添加到任何源代码控制系统。如果你正在使用SQL Server，那么我的解决方案在这里:http://dbsourcetools.codeplex.com/。玩得开心。 -内森。

每个推荐RedGate工具的人都要加1分，还有额外的建议和警告。

SqlCompare also has a decently documented API: so you can, for instance, write a console app which syncs your source controlled scripts folder with a CI integration testing database on checkin, so that when someone checks in a change to the schema from their scripts folder it's automatically deployed along with the matching application code change. This helps close the gap with developers who are forgetful about propagating changes in their local db up to a shared development DB (about half of us, I think :) ).

A caveat is that with a scripted solution or otherwise, the RedGate tools are sufficiently smooth that it's easy to forget about SQL realities underlying the abstraction. If you rename all the columns in a table, SqlCompare has no way to map the old columns to the new columns and will drop all the data in the table. It will generate warnings but I've seen people click past that. There's a general point here worth making, I think, that you can only automate DB versioning and upgrade so far - the abstractions are very leaky.

您还可以考虑迁移解决方案。它们允许您在c#代码中指定数据库模式，并使用MSBuild上下滚动数据库版本。

我目前正在使用DbUp，它工作得很好。

我还使用了数据库中通过数据库扩展属性家族存储的一个版本的过程。我的应用程序有脚本的每个版本的步骤(即。从1.1移动到1.2)。部署时，它会查看当前版本，然后逐个运行脚本，直到到达最后一个应用程序版本。没有脚本有直接的“最终”版本，即使部署在干净的DB上也会通过一系列升级步骤进行部署。

Now what I like to add is that I've seen two days ago a presentation on the MS campus about the new and upcoming VS DB edition. The presentation was focused specifically on this topic and I was blown out of the water. You should definitely check it out, the new facilities are focused on keeping schema definition in T-SQL scripts (CREATEs), a runtime delta engine to compare deployment schema with defined schema and doing the delta ALTERs and integration with source code integration, up to and including MSBUILD continuous integration for automated build drops. The drop will contain a new file type, the .dbschema files, that can be taken to the deployment site and a command line tool can do the actual 'deltas' and run the deployment. I have a blog entry on this topic with links to the VSDE downloads, you should check them out: http://rusanu.com/2009/05/15/version-control-and-your-database/

在迁移到x64平台后，我们需要对SQL数据库进行版本调整，而旧版本在迁移过程中出现了问题。我们写了一个c#应用程序，使用sqlmo将所有SQL对象映射到一个文件夹:

                Root
                    ServerName
                       DatabaseName
                          Schema Objects
                             Database Triggers*
                                .ddltrigger.sql
                             Functions
                                ..function.sql
                             Security
                                Roles
                                   Application Roles
                                      .approle.sql
                                   Database Roles
                                      .role.sql
                                Schemas*
                                   .schema.sql
                                Users
                                   .user.sql
                             Storage
                                Full Text Catalogs*
                                   .fulltext.sql
                             Stored Procedures
                                ..proc.sql
                             Synonyms*
                                .synonym.sql
                             Tables
                                ..table.sql
                                Constraints
                                   ...chkconst.sql
                                   ...defconst.sql
                                Indexes
                                   ...index.sql
                                Keys
                                   ...fkey.sql
                                   ...pkey.sql
                                   ...ukey.sql
                                Triggers
                                   ...trigger.sql
                             Types
                                User-defined Data Types
                                   ..uddt.sql
                                XML Schema Collections*
                                   ..xmlschema.sql
                             Views
                                ..view.sql
                                Indexes
                                   ...index.sql
                                Triggers
                                   ...trigger.sql

然后，应用程序将新编写的版本与存储在SVN中的版本进行比较，如果存在差异，则更新SVN。 我们确定每晚运行一次流程就足够了，因为我们没有对SQL做那么多更改。它允许我们跟踪所有我们关心的对象的变化，并且允许我们在发生严重问题时重新构建完整的模式。

这是围绕发展的“难题”之一。据我所知，没有完美的解决方案。

如果只需要存储数据库结构而不需要存储数据，则可以将数据库导出为SQL查询。(在企业管理器中:右键单击数据库->生成SQL脚本。我建议在选项卡上设置“每个对象创建一个文件”)，然后您可以将这些文本文件提交到svn，并使用svn的diff和日志功能。

我将此与一个Batch脚本绑定在一起，该脚本采用一对参数并设置数据库。我还添加了一些额外的查询，输入默认数据，如用户类型和管理用户。(如果你想要更多关于这方面的信息，张贴一些东西，我可以把脚本放在可以访问的地方)

如果你需要保留所有的数据，我建议保留一个数据库备份，并使用Redgate (http://www.red-gate.com/)产品进行比较。它们并不便宜，但它们值每一分钱。
