I have created a user with database roles db_datareader, db_datawriter and public. Also I have configured with server roles as public.
Now this user cannot view the list of stored procedure when clicking on stored procedures node in objects explorer. How can I assign permission to see and execute all the stored procedures? I want to do this through SSMS without launching any command.
I am using SQL Server 2012 and below versions:
Microsoft SQL Server Management Studio 11.0.2100.60
Microsoft Data Access Components (MDAC) 10.0.17763.1
Microsoft MSXML 3.0 4.0 5.0 6.0
Microsoft Internet Explorer 9.11.17763.0
Microsoft .NET Framework 4.0.30319.42000
Sistema operativo 6.3.17763
Looks like you can do this, though not as "simple" as you would expect.
I would, personally create a database role to do this. Go to your database in the Object explorer, and expand the Security Folder. Then right click Roles and Select New -> New Database Role.
Give the Role a name (I'll use db_executor) on the General Pane and then go to the Securables Pane. Click Search... at the top and select the radio option Specific Objects... and click OK. Click Object Types... and then tick Databases and then OK. Now click Browse... and tick the database you are adding the role to, then click OK and then OK.
In the datagrid at the bottom locate the Permission Execute, and tick the box in the column Grant. Then OK. This will run the below SQL on your instance:
USE [YourDatabase]
GO
CREATE ROLE [db_executor]
GO
use [YourDatabase]
GO
GRANT EXECUTE To [db_executor]
GO
Yes, Microsoft really is inconsistent with the casing of USE for that statement, and it omits the ; in it's commands.
Now you have created the role, locate the user you want to give access to in the object explorer in the Users folder. Right Click them and select Properties. Go to the Membership Pane and tick the box next to db_executor. Then click OK. This will run the below SQL on your instance:
USE [YourDatabase]
GO
ALTER ROLE [db_executor] ADD MEMBER [YourUser]
GO
Of course, why you wouldn't just run the 2 above commands, which is far quicker, I do not know.
I don't think there's a graphical way of doing this within the UI, but you can create a new query window in SSMS and execute one of these queries.
For a particular role you can:
/* GRANT EXECUTE TO THE ROLE */
GRANT EXECUTE TO role_what_needs_permissions
For a user
USE [the_database]
GO
GRANT EXECUTE TO [the_user]

I have a database Server with 10 databases. One of the users is with only access to 1 database.
I would like to add this user with all the permissions that they already have to all other databases. Is there anyway where I can do it?
Or do I need to create the same user for each database?
I am using SQL Server Management Studio 2018.
Thanks.
In SSMS go to securities (under database) -> logins
Then select your user and with mouse right click select properties. Then in new window select user mapping tab. Here you select all the databases you want them to give access to. (Here you can also set roles for them). Click OK and you are done. Now they have access to all the databases.
As business need I revoke
REVOKE EXECUTE ON SP_HELPTEXT TO PUBLIC;
it solve the purpose in query window, but how can I disable <modify> option present in object explorer.
WITH ENCRYPTION also solves the need, but not feasible in current situation. Please help me if having any other alternative.

You can also do it through the GUI by right clicking on the user or the proc and going to properties. The exact steps depend on whether you are using enterprise manager or sql management studio.
Alternately add them to a role that has permissions on it already, public is the minimum required.
exec sp_addrolemember 'public', 'user'
I am trying to grant a domain user to SQL Server 2008. This user should be able to login to the DB using server management studio, and run PowerShell scripts doing SELECT queries to a database. My problem is my settings does not persist.
In server management studio, I right click on Security->Logins->right click on ->Properties->User mappings-> tick my database which happens to be the first one, granted 'db_datareader' and 'public'.
Click OK.
No error pops up.
But when I check the user mappings again, my database is no longer ticked! What have I missed? Really puzzled... must be something very simple...
--update--:
soved: deleted the login+user, added them back,and the rest.. now ok. many thx!
It happens sometimes when user has no connect permission or the permission has been revoked.
Grant connect to [user]
use master;
GO
create login [<domain\user>] from windows;
GO
use [<yourdb>];
GO
create user [<domain\user>] for login [<domain\user>];
GO
ALTER ROLE db_datareader ADD MEMBER [<domain\user>];
GO
Is there a way to prevent users from getting into SQL Server Management Studio so that they can't just edit table rows manually? They still need to access the tables by running my application.
You can use the DENY VIEW ANY DATABASE command for the particular user(s). This is a new feature available in SQL Server 2008.
It prevents the user from seeing the system catalog (sys.databases, sys.sysdatabases, etc.) and therefore makes the DB invisible to them in SQL Management Studio (SSMS).
Run this command from the Master Database:
DENY VIEW ANY DATABASE TO 'loginName'
The user is still able to access the database through your application. However, if they log in through SSMS, your database will not show up in the list of databases and if they open a query window, your database will not appear in the dropdown.
However, this is not fool-proof. If the user is smart enough to run the Query Command:
USE <YourDatabaseName>
Then they will see the database in the Query Analyzer.
Since this solution is taking you 90% there, I would give the database some obscure name not let the users know the name of the database.
You DO NOT need to worry about them having access to the tool. Simply make sure they do not know any of the SQL logins for the specific Databases that have read/write permissions, if they do, change the password. If they have access to the DB via Windows Authentication, make sure that they are in a datareader role. You can use roles to manage what the users can do in SQL.
You can use a trigger.
CREATE TRIGGER [TR_LOGON_APP]
ON ALL SERVER
FOR LOGON
AS
BEGIN
DECLARE #program_name nvarchar(128)
DECLARE #host_name nvarchar(128)
SELECT #program_name = program_name,
#host_name = host_name
FROM sys.dm_exec_sessions AS c
WHERE c.session_id = ##spid
IF ORIGINAL_LOGIN() IN('YOUR_APP_LOGIN_NAME')
AND #program_name LIKE '%Management%Studio%'
BEGIN
RAISERROR('This login is for application use only.',16,1)
ROLLBACK;
END
END;

I would suggest you lock down the database and give appropriate read-only (or other) rights to the user. That way the user can still use management studio to run select queries and such.
If you don't want the user to have any rights at all then you could do that as well.
If your application is running as a service/user account then only that account requires access to the database. The individual users' account do not require any access to the database and therefore they won't even have read access. Your app will be the gateway to the data.
If the users are running the application under their user accounts then grant them read-only permission. You can simply add them to the db_datareader role.
Hope this helps!
You can deny 'Users' access rights to the ssms.exe executable file, while granting the relevant users/administrators rights to it.
If your application only used stored procedures to modify the data, you could give the end users access to run the stored procs, but deny them access to modify the tables.
Don't let them know what the database login is.
If you can't restrict the login, use stored procedures exclusively for updates and disable any CREATE,DELETE,INSERT, or UPDATE permissions for that user.
An Application Role will allow you to secure database objects to your application instead of the logged on user.
I agree with Jon Erickson as a general rule
do not allow any users access to the tables, but only allow access through stored procs
do not allow general user accounts access to stored procs, but only the account your app runs under (whether it's an integrated login or SQL login)
Make well usage of Database Roles, if Users should only have SELECT (read) access assign them the db_datareader Role. Even if they login using SSMS they will can execute only SELECT statements.
How can you hide databases you do not have access rights to when logging into SQL Server 2005 / 2008?
Currently if a user connects, they see all the databases on the server, meaning they have to scan though the list to find their database.
After hours of trying to figure out how to create a user account which only has access to 1 DB, and can only see that DB. I think i figured it out!!!!
Create a user account ( make sure its not mapped to any Database, otherwise you will get the final error Msg 15110, Level 16, State 1 and note proposed solution)
USE [master]
GO
CREATE LOGIN [us4]
WITH PASSWORD=N'123',
DEFAULT_DATABASE=[master],
CHECK_EXPIRATION=OFF,
CHECK_POLICY=OFF
Right Click on the upper section of the SQL (SQLSERVER Name)>Properties>Permissions>Click on the user account, and select Deny to view databases.
use [master]
GO
DENY VIEW ANY DATABASE TO [us4]
Right Click on the newly created DB, Properties,Files, and change the Owner to the newly created account.(important note: ALTER ROLE [db_owner] ADD MEMBER [us4] does not work)
USE [dbname]
GO
EXEC dbo.sp_changedbowner #loginame = N'us4', #map = false
At this point, once the user logs in he will see the Master,tempdb and will also see the new DB which he is a DB Owner of..You may want to go to Tools>Option and enabled the option to hide system objects so that you don't show the master,tempdb,etc. You may also need SP1 if this option does not work
Msg 15110, Level 16, State 1, Line 1
The proposed new database owner is already a user or aliased in the database.
proposed solution to Msg 15110: to resolve above error simply delete the user from database security node and try again
Hope that helps...

This actually won't work the way that makes sense or that you might expect that it would.
You REVOKE VIEW ANY DATABASE from the public role, but then the user has to be the database owner of the database or it can't be seen, but it still can be accessed.
The problem is a Database Engine Security shortcoming and not likely to be fixed in the current or future release of SQL Server.
Erland Sommarskog opened the following connect item for this a while ago, and it recently was discussed on twitter and with Microsoft by the SQL MVP's.
Vote for the connect and help make it more of a priority for Microsoft to fix:
Connect Feedback
Basically the permissions are stored at the database level, so it would require enumerating each database to determine if the user has connect rights to display the database in the object explorer, which is an expensive task to perform and how the older EM used to do things.
The proposes solution is for this information to be maintained at the server level as well, which is a major change.
You would need to revoke the permission 'VIEW ANY DATABASE' from the role PUBLIC (SQL SERVER 2005 onwards)
Add user to DB as Db owner after removing VIEW ANY DATABASE rights
This will show only the database owned by the login in SSMS.
USE master; GO
DENY VIEW ANY DATABASE TO [loginname]; GO
USE [your db]; GO
DROP USER [loginname]; GO
USE master; GO
ALTER AUTHORIZATION ON DATABASE::[your db]TO [loginname]; GO
Note: this requires the login to exists already
There appears to be a server-side setting on MS SQL 2005 and 2008 to restrict the databases a user may see. I found the following text at sql-server-performance.com
In SQL Server 2005 it is possible with a new server side role that has been created. VIEW ANY DATABASE permission is a new, server-level permission. A login that is granted with this permission can see metadata that describes all databases, regardless of whether the login owns or can actually use a particular database. Please note By default, the VIEW ANY DATABASE permission is granted to the public role. Therefore, by default, every user that connects to an instance of SQL Server 2005 can see all databases in the instance.
