How to give a user only select permission on a dat

问题:

I want a to create a new user on a db with only the select permissions (read only access) how can i do this ? i'm working with sql 2008

回答1:

You could add the user to the Database Level Role db_datareader.

Members of the db_datareader fixed database role can run a SELECT statement against any table or view in the database.

See Books Online for reference:

You can add a database user to a database role using the following query:

EXEC sp_addrolemember N'db_datareader', N'userName'

For the GUI minded people, you can:

• Right click the Database in Management Studio.
• Choose Properties
• Select Permissions
• If your user does not show up in the list, choose Search and type their name
• Select the user in the Users or Roles list
• In the lower window frame, Check the Select permission under the Grant column

You can use Create USer to create a user

CREATE LOGIN sam
    WITH PASSWORD = '340$Uuxwp7Mcxo7Khy';
USE AdventureWorks;
CREATE USER sam FOR LOGIN sam;
GO 

and to Grant (Read-only access) you can use the following

GRANT SELECT TO sam

Hope that helps.

create LOGIN guest WITH PASSWORD='guest@123', CHECK_POLICY = OFF;

Be sure when you want to exceute the following

DENY VIEW ANY DATABASE TO guest;

ALTER AUTHORIZATION ON DATABASE::BiddingSystemDB TO guest

Selected Database should be Master
