How to Create a User Server Role in SQL Server?

Published in Database Administration 3 mins read

You can create a user server role in SQL Server using the CREATE SERVER ROLE statement. This role grants specific permissions to users at the server level, allowing them to access and manage various server-level objects and functionalities.

Steps to Create a User Server Role:

  1. Connect to SQL Server: Establish a connection to your SQL Server instance using SQL Server Management Studio (SSMS) or any other compatible tool.

  2. Open a New Query Window: Create a new query window to write your SQL statement.

  3. Use the CREATE SERVER ROLE Statement: Execute the following SQL statement, replacing "your_server_role_name" with your desired server role name:

    CREATE SERVER ROLE your_server_role_name;

  4. Grant Permissions (Optional): After creating the server role, you can grant specific permissions to it. This can be done using the GRANT statement. For example, to grant the "CONNECT SQL" permission to your server role:

    GRANT CONNECT SQL TO your_server_role_name;

    You can find a list of available server-level permissions in the SQL Server documentation.

  5. Add Users to the Server Role: You can add users to your server role using the ALTER SERVER ROLE statement. For instance, to add a user named "your_user_name" to the "your_server_role_name" role:

    ALTER SERVER ROLE your_server_role_name ADD MEMBER your_user_name;

Example:

Let's create a server role named "DatabaseAdmin" and grant it the "CONTROL SERVER" permission. Then, we'll add a user named "JohnDoe" to this role:

-- Create the server role
CREATE SERVER ROLE DatabaseAdmin;

-- Grant permissions to the server role
GRANT CONTROL SERVER TO DatabaseAdmin;

-- Add a user to the server role
ALTER SERVER ROLE DatabaseAdmin ADD MEMBER JohnDoe;

Practical Insights:

  • Security Best Practices: Always use the principle of least privilege when assigning permissions to server roles. Grant only the necessary permissions to users and roles.
  • Server-Level Permissions: Server roles provide a way to manage access to server-level objects and functionalities, such as databases, logins, and server configurations.
  • User Roles: You can also create user roles within specific databases to manage access to database objects.

Remember to consult the SQL Server documentation for a comprehensive list of available permissions and their descriptions.
