我有两个数据库LIVE和DEVEL。我目前正在DEVEL工作，并创建并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方法将数据从LIVE复制到DEVEL但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，但是我得到的错误如下：
违反PRIMARY KEY约束'PK_Currency_Rate'。无法插入 对象'dbo.Currency_Rate'中的重复键。
所以它不会丢弃并重新创建表格。
我需要经常将数据从LIVE迁移到DEVEL，但还没有找到一种方法，这会阻碍我，因为我无法测试已实现的功能。
有没有经验丰富的人能指出我正确的方向？我对RedGate SQL Compare等付费第三方工具不感兴趣所以请不要建议

我会确保我的所有SP都编写成可以按需重新运行的文件。
VS中有比较工具允许您编写更改脚本，或者您可以手动进入DEVEL数据库，展开Programmability＆gt; Stored Procedures个节点，右键点击新的SP并选择Script Stored Procedure＆gt; Create to＆gt; File并将其保存在适合您项目的地方。
假设是这种情况，如果只是简单地将您的LIVE数据库恢复到DEVEL DB的顶部，您可以在DEVEL上重新运行SP脚本，这将解决问题。

对您的表执行此查询，复制输出数据并在另一个数据库上运行它。

如果您需要复制数据库，请备份数据库（右键单击数据库 - ＆gt; Tasks - ＆gt; Back Up...），然后将其还原（右）点击Databases - ＆gt; 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，然后我将复制数据。
