I have SQL Server 2005 Enterprise edition on one of my 64 bit machine with SQL collation SQL_Latin1_General_CP850_CI_AS .
Once it was required to change the collation.So i detached my all databases and uninstall SQL server and then reinstall the same version -SQL Server 2005 Enterprise edition with SQL Collation SQL_Latin1_General_CP1_CI_AS .
Now after that when i am attaching my databases i am having following error and databases are unable to attach:
The database 'Catalogue' cannot be opened because it is version 612. This server supports version 611 and earlier. A downgrade path is not supported.
Could not open new database 'Catalogue'. CREATE DATABASE is aborted. (.Net SqlClient Data Provider)
Can any one please guide me in this regard.I am unable to understand version 612 and 611.Whats this?

In most cases you have to upgrade your server because your database has been migrated to newer version of SQL Server.

Make sure you have installed the latest service packs and try again.

What version did you install. Did you install the CTP or the RTM version?

611/612 are two SQL Server 2005 versions.

If all you need is to change collation in one database all you need is alter database command... check here http://msdn.microsoft.com/en-us/library/ms174269.aspx

changing collation is a VERY complex subject:

1) differences between server/database collation will cause errors

2) after altering column collation you will only change collation for new rows - old will still have the old one ...

errors you mentioned (sql atached errors) - it means that before reinstallation your sql was at higher version - nothing more 😉 you should make proper updates and try reatached databases.

Hi,

Yeah the issue have been resolved as i have forgot to install latest Service packs after the installation.

Thanks for your guidance
