MS SQL Server Interview Question:

How to grant a permission in MS SQL Server using "GRANT EXECUTE" statements?

Submitted by: Administrator

This answer is about creating login and configure users for databases with Transact-SQL statements. Granting a user access to a database involves three steps. First, you create a login. The login lets the user connect to the SQL Server Database Engine. Then you configure the login as a user in the specified database. And finally, you grant that user permission to database objects. This answer shows you these three steps, and shows you how to create a view and a stored procedure as the object. This tutorial assumes that you are running SQL Server Management Studio Express.

As an administrator, you can execute the SELECT from the Products table and the vw_Names view, and execute the pr_Names procedure; however, Mary cannot. To grant Mary the necessary permissions, use the GRANT statement.

Procedure Title - Execute the following statement to give Mary the EXECUTE permission for the pr_Names stored procedure.


GRANT EXECUTE ON pr_Names TO Mary;
GO

In this scenario, Mary can only access the Products table by using the stored procedure. If you want Mary to be able to execute a SELECT statement against the view, then you must also execute GRANT SELECT ON vw_Names TO Mary. To remove access to database objects, use the REVOKE statement.

Note: If the table, the view, and the stored procedure are not owned by the same schema, granting permissions becomes more complex. For information about how to configure permissions on objects with different owners, see Ownership Chains.

About GRANT You must have EXECUTE permission to execute a stored procedure. You must have SELECT, INSERT, UPDATE, and DELETE permissions to access and change data. The GRANT statement is also used for other permissions, such as permission to create tables.
