How to change sql login username instead of create new one.

As title, thanks!Can you explain what you mean by "change sql login username"? Are you referr
ing to the login name
(in master) or the user name (in your database)? Anyhow, you cannot change t
he name of a login or a
user, You will be able to rename a user in 2005, not sure about login, thoug
h.

Yes, you can rename a SQL Server Login. You have to manually change values
in master.dbo.syslogins and master.dbo.sysxlogins.
