Introduction

A database administrator must ensure that a user has the necessary permissions to access the database and its objects after receiving a new server login. Permissions such as read, write, execute, create, etc., in SQL Server fall under the security context. So here, the purpose of assigning permissions to the MS SQL server comes into action. 

This article will help you understand different methods to assign permissions to the Microsoft SQL Server.

Permissions to MS SQL Server

The term "Permissions" refers to the regulations that set user access levels to secured SQL Server resources. 

The types of access given to particular securable are called Permissions. Permissions are granted to SQL Server logins and server roles at the server level. They are assigned to database users and database roles at the database level.

There are three main ways to control permissions:

  1. GRANT:  The GRANT statement grants principals access to particular secure resources.
     
  2. DENY: The DENY statement restricts principals' access to specific secure resources.
     
  3. REVOKE: Permissions previously given for specified securable are removed via the REVOKE statement.
     

Make a note that DENY permission can override all granted permissions.

Hierarchy of Permissions

Servers, databases, schemas, and the objects included within those schemas make up the hierarchy of Securables. Permissions can be set at the server, database, schema, or single object levels.

Unless you specifically tell the objects that belong to the children and grandchildren of the securable that they cannot have those permissions or deny them, permissions provided at a higher level of the hierarchy automatically apply to lower levels.

Methods to give permissions to MS SQL Server

Giving access to SQL server users can be done in two ways:

  1. Using T-SQL
  2. Using SSMS(SQL Server Management Studio)

Using T-SQL

Using T-SQL, you should first select a database using the use statement before you can provide authorization to a user. The grant statement is then used to give the user permission. The SQL server creates a user and grants permission syntax is as follows:

Use <database name>
Grant <permission name> on <object name> to <username\principle>

 

Example

Run the following query to grant the user "TestUser" select permission to the database "TestDB" object "TestTable."

USE TestDB
GO
Grant select on TestTable to TestUser

SSMS(SQL Server Management Studio)

  1. Connect to the instance and expand the folders.

    Object Explorer
    Source
     
  2. Do right-click on TestUser and select Properties

    TestUser
    Source
     
  3. To select your search:

    1. Click the Search button.
       
    2. Click Object Types, then select tables and click on browse.
       
    3. Click "TestTable" and then "OK."

      Select your search
      Source
       
  4. Check the Grant column box under "Select permission" and click "OK."

    Grant column box
    Source
     
  5. Click permission on 'TestTable' of TestDB database granted to 'TestUser,' then Click OK.

SQL Server Security

To effectively manage your SQL Server permissions, you must have visibility into them. You can learn more about permissions and keep track of changes to them with the help of the below-mentioned ways:

  1. Control over SQL Server permissions: It helps you determine how those permissions were granted and who has access to what in SQL Server.
     
  2. Server level change auditing: Keeps track of all modifications to the SQL Server setup, such as adjusting the permissions or removals of SQL server instances.
     
  3. Database-level change auditing: changes to database objects and content.

Frequently Asked Questions

How do you grant permissions in SQL?

Open the SQL Server Management Studio and then click on log in. Expand the Databases folder in Object Explorer's left-hand window, then choose the appropriate database and move on by expanding the Users and Security folders. Right-click on the user whose permissions you want to GRANT or REVOKE.

How do you permit to run a user in SQL Server?

Right-click the procedure you want to assign permissions to after expanding Stored Procedures and then choose Properties. Select the Permissions page from the Stored Procedure Properties. Select search to assign permissions to a user, database role, or application role.

What are SQL Server roles?

You may control server-level permissions and group user logins using SQL Server roles. They are essential to the security of SQL Server. There are two different roles in SQL Server: Fixed server roles, built of SQL Server, do not let you change user-defined or permission-based roles.

What is public permission in SQL Server?

Unlike other fixed roles in SQL Server, the public role allows for the granting, denying, and revocation of permissions. The public role is automatically assigned to a newly formed SQL Server login and cannot be revoked.

Conclusion

This article extensively discussed how to assign permissions to the Microsoft SQL Server in detail. We started with an introduction and debated the definition of an MS SQL server. Later, we also discussed the methods to assign permissions to Microsoft SQL Server.
