How do I script a password change for a SQL server login?

Question

正如标题所说，我需要更改现有sql server登录的密码，我想通过sql脚本来完成。

Answer 1

If the user already has the ALTER ANY LOGIN permission (ie the user can change any password for any user) then this works:

alter login mylogin with password = 'mylogin'

Otherwise, if you don't want to make every user in your system a superuser, add a parameter of the old password for the same command:

alter login mylogin with password = 'mylogin' old_password='oldpassword'

Answer 2
