Sadly, I've seen more than one team developing PL/SQL programs (stored procedures in Oracle) - sometimes ten thousands LOC - just by editing the code in TOAD (a database tool), without even saving the source to files (except for deployment). Even if the database is backuped regulary (wouldn't take that for granted, though), the only way to retrieve an old version of a stored procedure is to restore the whole database, which is many GB large. And of course sometimes concurrent changes in one file lead to loss of work, when more than one developer works on the same project.

我有一切必要的重新创建我的数据库从裸露的金属，减去数据本身。我相信有很多方法可以做到这一点，但我所有的脚本等都存储在subversion中，我们可以通过将所有这些从subversion中取出并运行安装程序来重建DB结构等。

是的，我们通过保留SQL作为构建的一部分来做到这一点——我们保留DROP。sql,创造。sql,用户。sql,值。SQL和版本控制，所以我们可以恢复到任何带标签的版本。

我们还有ant任务，可以在需要时重新创建db。

此外，SQL还被标记为与之配套的源代码。

是的，当然。每当有更改时，我们生成PostgreSQL模式的转储并签入。它已经救了我们很多次，而我才上任几个月。

Your project team can have a DBA to whom every developer would forward their create alter, delete, insert/update (for master data) sql statements. DBAs would run those queries and on successfully making the required update would add those statements to a text file or a spreadsheet. Each addition can be labeled as a savepoint. Incase you revert back to a particular savepoint, just do a drop all and run the queries uptil the labelled savepoint. This approach is just a thought... a bit of fine tuning here would work for your development environment.

在我们的业务中，我们使用数据库更改脚本。运行脚本时，它的名称存储在数据库中，并且不会再次运行，除非删除该行。脚本是基于日期、时间和代码分支命名的，因此可以控制执行。

在脚本在实际环境中运行之前，已经完成了大量的测试，所以一般来说，“oopsies”只发生在开发数据库上。
