How to update a SQL database during patch
I have an app using Sql server express/VB.net, installation & patches using Installshield 2007. As yet I have not designed any patches for my system and I was wondering firstly what basic way I should deal with updating a database scheme during an update of my software whilst retaining any data already input. Is there an industry standard way of doing this or a clever way or should I buy some third party software that applies database changes to an existing schema and build that in to my Installshield patch?
I am reletively inexperienced in the whole setup design and use a contractor but have never managed to get a coherrent answer that i understand with regard to schema changes and Installshield patches.
Any help would be extremely welcome.

This really has nothing to do with packaging per-se. What you need to do is run a Custom Action which runs a SQL script against the database. Have your DBA create the script, ensuring that he/she signs it off as tested and operational. If you have no DBA, I'd make a copy of the d/b and test your own script against it. When you're 100% sure the script does what it's supposed to do, add it to your favoured SQL execution tool's command line. I guess, given that you're using SQL Server Express, that that would be OSQL.EXE. When you're happy with that, copy the command line to your Custom Action.
Rating comments in this legacy AppDeploy message board thread won't reorder them,so that the conversation will remain readable.
