Study Notes

Managing Permissions in Databricks SQL

Begin by navigating to the Databricks SQL Workspace and ensure the SQL warehouse is operational.
Access the SQL editor from the left sidebar to create a new database named "HR DB."
Inside "HR DB," set up a table called "employees" with columns: ID, name, salary, and city.
Insert data into the "employees" table and create a view specifically for employees residing in Paris.

Granting Permissions

Configure permissions to allow the HR Team to read, modify data, access metadata, and create new database objects.
Granting privileges requires the USAGE privilege for users to interact with database objects.
Use a specific SQL command to grant access, allowing actions to be performed by selecting and running the command.

Individual User Permissions

Individual users can be assigned specific privileges, such as granting read access on views to users outside the HR team.

Reviewing Permissions

Use the SHOW GRANTS command to review assigned permissions for the HR team and verify ownership of the database.
Confirm users like Adam have SELECT privilege on views inherited from the database.

Data Explorer Overview

The Data Explorer tool allows for easier navigation and management of databases, tables, and views.
Access the Data Explorer via the Data tab on the left sidebar to explore the schema, metadata, and history of data objects.
Review the Permissions tab to see current permissions and revoke any as necessary.
Change database ownership from an individual to a group, such as the admin group.

Granting Permissions to All Users

Grant all users the ability to review metadata by selecting the appropriate privileges and groups in the Data Explorer.
Assign the SELECT privilege to all users for querying tables within the Data Explorer.

Query History

All SQL queries executed within Databricks SQL, including those from the Data Explorer, can be viewed in the Query History section of the left sidebar.
The Query History provides a comprehensive record of all executed commands for transparency and tracking purposes.
