About sp_detach_db and sp_attach_db

Hello there,
Our database data and log files were stored on UNC directory on different
server, we are thinking to use sp_detach_db and sp_attach_db to move data an
d
log files from UNC to local disk. Becasuse we are not familiar about
application, any minor issue could stop applicaiton. Is there any issue coul
d
happen on sp_detach_db and sp_attach_db?
Thanks very much
LionelI haven't had any problems using them properly (that is, attaching databases
with sp_attach_db that were detached using sp_detach_db), but that doesn't
mean there is no possibility of issues. As with anything else, back up
first just to be on the safe side.

our database owner is "unknow", I wonder why it would be happed.
when we use sp_attach_db to change the database owner from "unknow" to "sa",
any issue could be?
Thanks again

sp_change_users_login and sp_changedbowner.

Before detaching, I recommend you to do a Full database backup of your
database. So even if Attach wont work you
could use the backup to recover the database to local hard disk using
RESTORE DATABASE command.
After that as Adam suggested you could use sp_changedbowner to change the
database owner
Thanks
