我有两个数据库LIVE和DEVEL. 我目前正在工作DEVEL并创建和修改了许多存储过程，但是我的测试数据用完了，所以我需要找到一种将数据复制到的方法，LIVE但DEVEL我不想丢失我的存储过程。

我正在使用 SQL Server 2008 Management Studio 并尝试过Tasks -> Export Data. 然后我选择Drop and recreate new destination tables但是我收到如下错误：

违反主键约束“PK_Currency_Rate”。无法在对象“dbo.Currency_Rate”中插入重复键。

所以它不会删除和重新创建表。

我需要经常将数据从 迁移LIVE到 ，DEVEL但还没有找到一种方法，这让我望而却步，因为我无法测试实现的功能。

那里有足够经验的人能指出我正确的方向吗？我对 RedGate SQL Compare 这样的付费第三方工具不感兴趣，所以请不要推荐它们

我会确保我所有的 SP 都被编写成可以按需重新运行的文件。

VS 中有一些比较工具可以让您编写更改脚本，或者您可以手动进入 DEVEL 数据库，展开Programmability>Stored Procedures节点，右键单击您的新 SP 并选择Script Stored Procedure> Create to>File并将其保存在您项目的合理位置。

假设是这种情况，如果您只是在 DEVEL 数据库的顶部恢复您的 LIVE 数据库，您可以在 DEVEL 上重新运行您的 SP 脚本，这将解决问题。

为您的表执行此查询，复制输出数据并在另一个数据库上运行它。

询问：

如果您需要制作数据库的副本，请备份数据库（右键单击数据库 --> Tasks--> Back Up...），然后恢复它（右键单击Databases-->Restore Database...

我会为这项工作准备 SSIS 任务。

作为每项任务的第一步，我将确保从目标表中删除数据，然后复制数据。
