Syntax
DROP LOGIN login_name
Arguments
- login_name
Specifies the name of the login to be dropped.
Remarks
A login cannot be dropped while it is logged in. A login that owns any securable, server-level object, or SQL Server Agent job cannot be dropped.
You can drop a login to which database users are mapped; however, this will create orphaned users. For more information, see Troubleshoot Orphaned Users (SQL Server).
Permissions
Requires ALTER ANY LOGIN permission on the server.

DROP LOGIN WilliJo;
