Synchronizing tables on different databases (SQL Server)

[riksweeney]

Is there a way to update a database's tables with the new columns from a master databases tables without losing the previous data? I'm basically looking for something that will script the changes so that I can just run the update script. Am I wishing too hard for this?

Check out SQLCompare. Go to

It is a good tool and we use it to move all our development changes to production without losing the data. It's even not expensive! They also have tool to compare data between tables.
