Hi i need to change my username password of my hsqldb. so where and how can I change my username password?. please help me to resolve this.
Thank you
Connect with the old user name and execute the statement below
SET PASSWORD 'newpassword'
If the user which is connected to the database is ADMIN, it can change the passwords of other users with this statement
ALTER USER "username" SET PASSWORD 'newpassword'
To create an ADMIN user with Username ROOT and Password ROOT:
CREATE USER ROOT PASSWORD ROOT ADMIN;

Is it possible to create a user by Admin without a password and instead get a temporary password on the email, get time-limited URL for the link to the form where the user should set password directly?
No this is not possible. You can set a temporary password and then force user to change it as soon as they log in.
I am developing a WPF application with SQL Server 2014.
In our server side, I have created SQL Login as
CREATE LOGIN <username> WITH PASSWORD = <oldPassword> MUST_CHANGE,CHECK_EXPIRATION=ON,CHECK_POLICY=ON, DEFAULT_DATABASE =<databaseName> DEFAULT_LANGUAGE=[English]
Now after changing the password of above user by
ALTER LOGIN <username> WITH PASSWORD = <newPassword> , OLD_PASSWORD =<oldPassword> , DEFAULT_DATABASE=<databaseName>, DEFAULT_LANGUAGE=[English]
I am able to open this connection with Old Password and new password both (by using VS2013 C# connection string ). Condition : It will work only till we restart our server or service.
As per the requirement, user should be able to login only with new password. Can this community help me.
Do we have some restriction in SQL to open connection/login only with New Password.
Thanks in Advance.
Try adding this to your command when changing the password.
OLD_PASSWORD = 'oldpassword'
I think you might just be adding another password rather than replacing it with your current command.
On appfuse (http://appfuse.org/display/APF/Demos), an Administrator can add users. When adding a new user, the administrator can set "Password Hint" for the user being added, but not the user's actual password. When the user comes to login, how will the user know his exact password, my question is?
When administrator add some user, they only filled the the password hint.
And the password will be sent to user's email that has been registered.
I created a login named mylogin with password= 'pass_1'
Then i logged into sql server using this login & tried to create a database , which gave the error that permission denied.
Then i executed this : sp_addsrvrolemember 'mylogin', 'dbcreator'
Then, again I logged into sql server using above login & tried to create a database, this time the database was created successfully
This was because I added the dbcreator server role for the login.
But, then i created a USER myloginuser for LOGIN mylogin ,
then executed this query:
execute as user = 'myloginuser'
then again i tried to create a database, but it failed. why so?
when the login MYLOGIN to which the user MYLOGINUSER is associated has the permission to create a database then why does the user does not have the permission? then whats the solution for this? do i have to grant permission to the user separately irrespective of the permissions granted to the login?
also, a user which is created for a login , have to be created inside a database? is it necessary?
The default user for the LOGIN [mylogin] was mylogin (which was created executing
sp_addsrvrolemember 'mylogin',
'dbcreator'
Hence this mylogin user had the db create permission. But you have created a MYLOGINUSER for the same Login. So the existing user mylogin was set to orphaned user, hence the mylogin Login dropped the db creator permission.
Is the SQL Server Authenticationmode set to Mixed instead of Windows?
Ypu'll have to set it to mixed.
A user must be created at the SQL Server level and given permissions in (mapped to) a database.
Just what the title says, I need to change the password for an existing sql server login and I want to do it via sql script.
If the user already has the ALTER ANY LOGIN permission (i.e. 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'
ALTER LOGIN

alter login mylogin with password = 'mylogin'
