在SQL Server 2008中最简单的方法来区分两个表模式？

Question

我必须在开发和发布数据库之间进行检查,并手动执行此操作,这既慢又不可靠(我只能直观地检查表).

有没有一种快速简便的方法来自动比较表模式？也许甚至一个功能,这内置到SQL服务器？

编辑:我只是比较结构,谢谢你指出这一点.

Answer 1

I'm a fan of SQL DBDiff, which is an open source tool you can use to compare tables, views, functions, users, etc. of two instances of SQL Server databases and generate a change script between the source and destination databases.

Answer 2

There are some commercial products that do this; Visual Studio 2010 Premium Edition can compare schemas.

Some others:

Answer 3

Data or structure or both? Try RedGate sql compare or data compare. They both have free trials and are awesome.

我在游戏中有点迟了......但我制作的这个剧本对我来说效果很好.如果需要,它也可以跨链接服务器工作.

苏，
