I want to create a database in sql server 2008. But i want only one user can access in this database. Neither trusted_Connection neither Username in managment studio MyPcname and password WindowsAuthentication.
Also how secure is my database if someone will keep mdf files and open then in another computer which other login users have all rights.
This is my code for creating a database and a login user
Create Database MyDb
CREATE LOGIN [admin] WITH PASSWORD='1234', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF;ALTER LOGIN [admin] Enable;EXEC sys.sp_addsrvrolemember #loginame = N'admin', #rolename = N'sysadmin'
Also i dont want to be seen if someone will login with local

We have moved our database from a physical server to a Azure PaaS SQL database. The server login is used by the application to connect to the database. I need to create another login account with read-only access to the database. Can someone please help.
Things i have tried already.
CREATE LOGIN login123
WITH PASSWORD = *******
CREATE USER login123
FOR LOGIN login123
WITH DEFAULT_SCHEMA = dbo
ALTER ROLE db_datareader ADD MEMBER login123
The above was executed successfully but when the application uses this login it gets the below error.
"The server pricipal "login123" is not able to access the database "master" under the current security context. Cannot open user default database. Login failed."
When you run this query:
CREATE LOGIN login123
WITH PASSWORD = *******
CREATE USER login123
FOR LOGIN login123
WITH DEFAULT_SCHEMA = dbo
ALTER ROLE db_datareader ADD MEMBER login123
This means that the new user only have the readonly permission for the database.
Which database the query run in, the readonly permission is for which database.
The user don't have the permission to access other database or master db.
For more details, please see:
Controlling and granting database access to SQL Database and SQL
Data Warehouse
Database-Level Roles
If you want the user both have the readonly permission to more database, you should create more user(with the same) in different database. Using one Login mapping to more users.
Here the T-SQL code, I tested and it works in Azure SQL database:
USE master
CREATE LOGIN login123
WITH PASSWORD = '****'
GO
CREATE USER login123
FOR LOGIN login123
WITH DEFAULT_SCHEMA = db_datareader
GO
USE Mydatabase
CREATE USER login123
FOR LOGIN login123
WITH DEFAULT_SCHEMA = dbo
GO
ALTER ROLE db_datareader ADD MEMBER login123
GO
``````
Hope this helps.
With Azure-Sql-database You can't use a sql server login to connect to the master database
You have to put in the connection string the database that you want to access.
you can find more information on this link :
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-manage-logins#non-administrator-users
I try (for the first time) to create a user account on my SQL Azure database.
I have read in some blogs that I have to create these command lines
CREATE LOGIN login_name WITH PASSWORD = 'strong_password';
CREATE USER 'user_name' FOR LOGIN 'login_name';
And then
USE [Database];
GO
GRANT CONNECT TO login_name;
But, when I try to connect with this new account on my database, I have the message error 916
The server principal "login_name is not able to access the database "master" under the current security context.
I don't understand because the don't create my new user for the master but for a specific database in my SQL Azure environment (I have 5 databases in my SQL Azure by the way)
If you have any idea to help me, thanks in advance
When first logging in, unless a database is specified in the connection string, a login connects to its default database. If the database is not specified in the CREATE LOGIN statement, the system default of master is used.
To fix this, use this for your CREATE LOGIN:
CREATE LOGIN login_name WITH PASSWORD = 'strong_password',
DEFAULT_DATABASE = MyDatabase;
I have SQL Server 2005, and I tried to create a new database with a user.
I used these commands with sa user on master db:
CREATE LOGIN mobstat WITH PASSWORD = 'mobstat123';
CREATE USER mobstat FOR LOGIN mobstat;
CREATE SCHEMA mobstat AUTHORIZATION mobstat;
CREATE DATABASE mobstat COLLATE SQL_Hungarian_CP1250_CI_AS;
EXEC sp_addrolemember N'db_owner', N'mobstat';
Every command executed well, but I cannot login with the new user.
The error is:
Cannot open database "mobstat" requested by the login. The login failed.
I've tried to Google it, but no result yet.
My client is DBeaver.
USE master;
GO
CREATE LOGIN mobstat WITH PASSWORD = 'mobstat123';
GO
CREATE DATABASE mobstat COLLATE SQL_Hungarian_CP1250_CI_AS;
GO
-- You were creating a schema and a User before you have created a database
USE [mobstat]
GO
CREATE USER mobstat FOR LOGIN mobstat;
GO
EXEC sp_addrolemember N'db_owner', N'mobstat';
GO
CREATE SCHEMA [mobstat] AUTHORIZATION [mobstat]
GO
I am trying to use the following template:
-- =================================================
-- Create User as DBO template for SQL Azure Database
-- =================================================
-- For login <login_name, sysname, login_name>, create a user in the database
CREATE USER <user_name, sysname, user_name>
FOR LOGIN <login_name, sysname, login_name>
WITH DEFAULT_SCHEMA = <default_schema, sysname, dbo>
GO
-- Add user to the database owner role
EXEC sp_addrolemember N'db_owner', N'<user_name, sysname, user_name>'
GO
I would like to create a user called user1 with a password of 'user1pass'. I connected with my default database 'authentication' and I have a query window open.
But the template does not make sense for me. For example what's sysname, where do I supply the password and what should I use as the default_schema?
The particular user needs to have the power to do everything. But how do I set it up so he can do everything, is that done if I make the user a database owner?
So far I have tried:
CREATE USER user1, sysname, user1
FOR LOGIN user1, sysname, user1
WITH DEFAULT_SCHEMA = dbo, sysname, dbo
GO
Giving:
Msg 102, Level 15, State 1, Line 1 Incorrect syntax near ','.
and:
CREATE USER user1
FOR LOGIN user1
WITH DEFAULT_SCHEMA = dbo
GO
Giving:
Msg 15007, Level 16, State 1, Line 1 'user1' i
s not a valid login or you do not have permission.
Edit - Contained User (v12 and later)
As of Sql Azure 12, databases will be created as Contained Databases which will allow users to be created directly in your database, without the need for a server login via master.
Sql (standard) User
CREATE USER [MyUser] WITH PASSWORD = 'Secret';
ALTER ROLE [db_datareader] ADD MEMBER [MyUser]; -- or sp_addrolemember
AAD linked User
CREATE USER [SomeUser#mydomain.com] FROM EXTERNAL PROVIDER;
EXEC sp_addrolemember 'db_datareader' , N'SomeUser#mydomain.com'
AAD linked Group
CREATE USER [SomeGroup] FROM EXTERNAL PROVIDER;
EXEC sp_addrolemember 'db_datareader' , N'SomeGroup'
NB! when connecting to the database when using a contained user that you must always specify the database in the connection string.
Traditional Server Login - Database User (Pre v 12)
Just to add to #Igorek's answer, you can do the following in Sql Server Management Studio:
Create the new Login on the server
In master (via the Available databases drop down in SSMS - this is because USE master doesn't work in Azure):
create the login:
CREATE LOGIN username WITH password=N'password';
Create the new User in the database
Switch to the actual database (again via the available databases drop down, or a new connection)
CREATE USER username FROM LOGIN username;
(I've assumed that you want the user and logins to tie up as username, but change if this isn't the case.)
Now add the user to the relevant security roles
EXEC sp_addrolemember N'db_owner', N'username'
GO
(Obviously an app user should have less privileges than dbo.)
Check out this link for all of the information : https://azure.microsoft.com/en-us/blog/adding-users-to-your-sql-azure-database/
First you need to create a login for SQL Azure, its syntax is as follows:
CREATE LOGIN username WITH password='password';
This command needs to run in master db. Only afterwards can you run commands to create a user in the database. The way SQL Azure or SQL Server works is that there is a login created first at the server level and then it is mapped to a user in every database.
HTH
I followed the answers here but when I tried to connect with my new user, I got an error message stating "The server principal 'newuser' is not able to access the database 'master' under the current security context".
I had to also create a new user in the master table to successfully log in with SSMS.
USE [master]
GO
CREATE LOGIN [newuser] WITH PASSWORD=N'blahpw'
GO
CREATE USER [newuser] FOR LOGIN [newuser] WITH DEFAULT_SCHEMA=[dbo]
GO
USE [MyDatabase]
CREATE USER newuser FOR LOGIN newuser WITH DEFAULT_SCHEMA = dbo
GO
EXEC sp_addrolemember N'db_owner', N'newuser'
GO
You can simply create a contained user in SQL DB V12.
Create user containeduser with password = 'Password'
Contained user login is more efficient than login to the database using the login created by master. You can find more details # http://www.sqlindepth.com/contained-users-in-sql-azure-db-v12/
I use the Azure Management console tool of CodePlex, with a very useful GUI, try it. You can save type some code.
1 Create login while connecting to the master db
(in your databaseclient open a connection to the master db)
CREATE LOGIN 'testUserLogin' WITH password='1231!#ASDF!a';
2 Create a user while connecting to your db (in your db client open a connection to your database)
CREATE USER testUserLoginFROM LOGIN testUserLogin;
Please, note, user name is the same as login. It did not work for me when I had a different username and login.
3 Add required permissions
EXEC sp_addrolemember db_datawriter, 'testUser';
You may want to add 'db_datareader' as well.
list of the roles:
https://learn.microsoft.com/en-us/sql/relational-databases/security/authentication-access/database-level-roles?view=sql-server-ver15
I was inspired by #nthpixel answer, but it did not work for my db client DBeaver.
It did not allow me to run USE [master] and use [my-db] statements.
https://azure.microsoft.com/en-us/blog/adding-users-to-your-sql-azure-database/
How to test your user?
Run the query bellow in the master database connection.
SELECT A.name as userName, B.name as login, B.Type_desc, default_database_name, B.*
FROM sys.sysusers A
FULL OUTER JOIN sys.sql_logins B
ON A.sid = B.sid
WHERE islogin = 1 and A.sid is not null
List of all users in Azure SQL
create a user and then add user to a specific role:
CREATE USER [test] WITH PASSWORD=N'<strong password>'
go
ALTER ROLE [db_datareader] ADD MEMBER [test]
go
I found this link very helpful:
https://azure.microsoft.com/en-gb/documentation/articles/sql-database-manage-logins/
It details things like:
- Azure SQL Database subscriber account
- Using Azure Active Directory users to access the database
- Server-level principal accounts (unrestricted access)
- Adding users to the dbmanager database role
I used this and Stuart's answer to do the following:
On the master database (see link as to who has permissions on this):
CREATE LOGIN [MyAdmin] with password='ReallySecurePassword'
And then on the database in question:
CREATE USER [MyAdmin] FROM LOGIN [MyAdmin]
ALTER ROLE db_owner ADD MEMBER [MyAdmin]
You can also create users like this, according to the link:
CREATE USER [mike#contoso.com] FROM EXTERNAL PROVIDER;
I think the templates use the following notation: variable name, variable type, default value.
Sysname is a built-in data type which can hold the names of system objects.
It is limited to 128 Unicode character.
-- same as sysname type
declare #my_sysname nvarchar(128);
how do you create a new database user with password in sql server 2005?
i will need this user/password to use in the connection string eg:
uid=*user*;pwd=*password*;
CREATE LOGIN [user] WITH PASSWORD='password',
DEFAULT_DATABASE=[your_db], CHECK_POLICY=OFF
GO
CREATE USER [user] FOR LOGIN [user]
EXEC sp_addrolemember N'db_datareader', N'your_db'
EXEC sp_addrolemember N'db_datawriter', N'your_db'
GO
Where CHECK_POLICY=OFF switches off password complexity check, etc
As of SQL Server 2005, you should basically create users in two steps:
create a "login" to your SQL Server as a whole
create users for this login in each database needed
You'd go about doing this like so:
CREATE LOGIN MyNewUser WITH PASSWORD = 'top$secret';
And the "USE" your database and create a user for that login:
USE AdventureWorks;
CREATE USER MyNewUser FOR LOGIN MyNewUser
As indicated, use the CREATE LOGIN to create the ability to connect to SQL Server as that account. Then use CREATE USER within the database to give that login the ability to access the database in question.
However, a few security points based on some of these comments:
If at all possible, you want to use Windows authentication, not a SQL Server based login (which is what you are doing when you use user/pwd in this manner). If you are running from a computer on the same domain as SQL Server, you can use a service account that is a Windows user account. This ensures the domain is the single source for security.
You didn't say what rights the user needed. Avoid using db_datareader and db_datawriter roles whenever possible. They give IMPLICIT access to tables and views and if someone is performing a quick permissions check on the database, they may not think to check the membership in these roles. That means your reporting on security is using. Best practices say to create your own database role, assign permissions to it, and make the user a member of that role.
Whenever possible, use a strong password. One example had the password policies turned off. SQL Server will use the password policy from the local server (which is usually set at the domain level). You want to maintain that strong password policy, if possible.
You'll have to create it first as a user, and then set up the correct permissions for the user.
you'll have to ensure that your DB is configured with both User auth and SQL auth
If using the Management Studio: right-click on the Server, select "Security" ensure that server authentication is "SQL Server and Windows Authentication mode"
in Security-logins, right click and select "New Login", select SQL Authentication, use the username and password you like.
USE [master]
GO
CREATE LOGIN [ test] WITH PASSWORD=N'test', DEFAULT_DATABASE=[MY_DATABASE], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO
on the DB you want, in security, users, select new User. Select a username, and attach the login name you've just created, and select the roles you want to apply to this user (i.e. db_datareader, db_datawriter):
USE [MY_DATABASE]
GO
CREATE USER [myDefaultUser] FOR LOGIN [ test]
GO
USE [MY_DATABASE]
GO
EXEC sp_addrolemember N'db_datareader', N'myDefaultUser'
GO
USE [MY_DATABASE]
GO
EXEC sp_addrolemember N'db_datawriter', N'myDefaultUser'
GO
That is it. Now you can create your connection string using this password.
CREATE LOGIN MyNewUser WITH PASSWORD = 'top$secret'
USE AdventureWorks
CREATE USER MyNewUser FOR LOGIN MyNewUser
GO
USE [MASTER]
EXEC master.dbo.sp_addlogin #loginame = N'USERNAME', #passwd = 'THEPASS' #defdb = N'master', #deflanguage = N'us_english'
USE [YOUR_DB]
EXEC dbo.sp_grantdbaccess #loginame = N'USERNAME', #name_in_db = N'USERNAME'
