How to migrate SQL data and keep SP's

Question

I have two databases LIVE and DEVEL. I am currently working in DEVEL and have created and modified a number of stored procedures however I am running out of test data so I need to find a way to copy data from LIVE to DEVEL but I don't want to lose my stored procedures.

I am using SQL Server 2008 Management Studio and have tried Tasks -> Export Data. I then pick Drop and recreate new destination tables however I get errors like:

Violation of PRIMARY KEY constraint 'PK_Currency_Rate'. Cannot insert duplicate key in object 'dbo.Currency_Rate'.

So it is not dropping and recreating the tables.

I need to migrate data from LIVE to DEVEL quite often but haven't yet found a way of doing it and this is holding me back because I cannot test the implemented functionality.

Could anyone out there experienced enough in the matter point me in the right direction? I am not interested in paid third party tools like RedGate SQL Compare so please do not suggest them

Answer 1

I would prepare SSIS task for the job.

As a first step for each task I would ensure that data is removed from destination tables, then I would copy data.

Answer 2

I would ensure all my SP's are scripted off into files I can re-run on demand.

There are comparison tools within VS which allow you to script off changes, or you can manually go into the DEVEL database, expand the Programmability > Stored Procedures node, right click you new SP's and select Script Stored Procedure > Create to > File and save it somewhere sensible with your project.

Assuming this is the case, if you simply restore your LIVE database over the top of your DEVEL DB you can re-run your SP scripts on DEVEL and this will resolve the issue.

Execute this query for your tables, copy output data and run it's on another database.

Query:

If you need to make a copy of your database, make a backup of the database (Right click on database --> Tasks --> Back Up...), then restore it (Right click on Databases --> Restore Database...
