Question : SQL Server Instance version & Database version

Currently we are facing issue with versions of databases in our company.
We have a SQL Server 2005 SP2 Enterprise Edition 64bit Instance. We restored a DB from older SQL 2000 32bit EE instance.

My question is: How to identify version of a databse? (if there is anything like that, I know how to check version of an instance by running command select @@version)

Also I have heard not sure though, If we detach a DB from SQL 2000 & attach it to SQL 2005 Instance. DB will still be SQL 200 running on SQL 2005 Server. How to check version of database in such a case?

Thanks
Josh

Answer : SQL Server Instance version & Database version

backup of database 2005 cannot be restored in sqlserver 2000. for restorin backup of 200 to 2005 you have to do it this way

create a new database in 2005 with the same name and compatibility set for SQL 2000 or the version you want to restore from.

restore this database with options 'overwrite existing database'
