Hello all,
I want to use ms sql 2005 in visual studio 2010. For this I changed the framework to 3.5 while creating new website but don;t know how it will create 2005 compatible database schema.
Please guide me.

Thanks

sophia, I could be misunderstanding but I'm not sure why you need to change to the 3.5 Framework in order to create a 2005-compatible database schema. The .NET Framework really has nothing to do with database schema: entirely different entities.

If you're talking about creating a project with an App_Data folder, for example, and adding a .mdf database file to your project, the version of the database will depend on what version of SQL Server Express you're currently running. For example, if you have SQL Server 2005 Express running, the database will be created in version 9 (or 2005). The .NET Framework's SQL data provider will still be able to fully interface with the database whether in v3.5 or v4.0. Happy coding!

Hi Guenfire,
actually on my machine I have VS2010 and hence Sql server 2008 by default. But my host provider still has lower version of VS and Sql server.
That's why I changed framework to 3.5 but database schema was still 2008 compatible.
So how I can host a site on lower version which is developed on higher version?

Many thanks for your kind reply.

Okay, I understand your issue now. You're talking about the compatibility level. If this is a database in your Visual Studio project (e.g., a .mdf file) you will have to first detach it from the project (hint: using right-click on the database), attach it to SQL Server using SQL Server Management Studio, then make the following change using SQL:

If your database is separate, you can just run the above query and that will then make the database 2005 compatible. Happy coding!

Hi guenfire,

what the above code is doing? and what 90 means?
Kindly tell me what is compatibility level for ms sql 2000.

Many thanks, I will sooner try it.

sophia, as I already explained the code sets the database to be compatible with a schema for SQL Server 2005. This link should provide answers to most of your questions: ALTER DATABASE Compatibility Level (Transact-SQL).
