SQL Server Instances

I have a SQL Server 2008 db that is on the MSSQLSERVER instance. I want another user who only has SQL Server 2008 express installed to be able to use an app that accesses that database.

How do I install the db on SQL E开发者_运维知识库xpress?

Will the user be accessing the same database? If so, you will need to ensure that the application can connect to the default instance on your pre-existing installation.

If you are talking about the same database schema, but just on a different location then you can just backup the database on the MSSQLSERVER instance and restore it on the SQL Express instance. SQL Express is a named instance so the connection string in the application will need to reflect something like .\SQLEXPRESS.

Also, versions will need to be considered. The SQL Express instance should be 2008 or 2008 R2 to not have compatibility issues.
