回复：请问我这样处理问题合适吗？

This could be process problem. You can send emails or talk with your boss about the development and QA process. In the emails, you can mention that someone didn't check out the latest codes. Don't mention the names. After you define the process, you can print it out and let everyone has a copy. Remind everyone the importance of the process. Also, make sure that your DBA know how to use the Source control tools.

Besides the above, I suggest that you should have unit tests before you implement the stored procedures. TDD could solve your problem.
