Lets say the db is know by its sysname. How do I change it to be sysname\instance_name in sql 2005?

you can rename the database , but a fully qualified database is known by instancename/database name anyway.

select convert(varchar(128),serverproperty('instancename'))

select @@servername

select convert(varchar(128),serverproperty('machinename'))

e.g.

instance102

myserver\instance102

myserver

add to the database name as required e.g.

select convert(varchar(128),serverproperty('instancename'))+'_'+db_name()

Are you wanting to rename an individual database or the SQL Server itself? If the latter, are you trying to make a default instance a named instance?

you cannot rename an instance, it has to be uninstalled and a new instance with the correct name needs to be created. that means backing up non-system databases, and then restoring them in the new instance.

I haven't seen a registry hack or anything that successfully changed an instance name yet.

for example, if you had SERVER\SQL2005 as an instance, and you wanted to rename the \SQL2005 for any reason, you have to uninstall the instance, and add the new one (ie SERVER\DEVELOPER

if you rename the server, it will automatically change to NEWSERVERNAME\SQL2005

Create the new instance, copy & attach all the databases, drop the old instance.

It is a pain in the tucas.
