How do you grant access to a table in Databricks?

Granting access to a table in Databricks is done by using the GRANT command. This command allows you to provide specific permissions to users or groups for a particular database object, such as a table, view, or database.

Using the GRANT command is crucial because it directly interacts with the security model in Databricks, allowing administrators to manage permissions effectively. By specifying the user or group and the type of access they will receive (such as SELECT, INSERT, UPDATE, etc.), you can ensure that the right people have the right level of access to the data.

The other methods listed do not serve the primary purpose of granting access. Creating a temp view is primarily for defining a temporary, non-persistent SQL view based on a dataset without impacting security levels. Modifying the database schema refers to structural changes within the database and does not pertain to access rights. Altering the table structure also relates to modifying the table itself, such as adding or deleting columns, rather than controlling who can access or use the table.

Therefore, using the GRANT command is the most direct and appropriate method for controlling access to tables in the Databricks environment.
