Practise · Real PostgreSQL
SQL lab
Use real SQL to complete a guided task in a temporary PostgreSQL database. Your lab is isolated from every other learner and is removed when you finish or when it expires.
Your goal
Recover a disposable cluster to a defensible target immediately before a known harmful data event and verify the state.
What to do
- Start your temporary database.
- Read the task and run SQL in the workspace.
- Check your work. The server will inspect the database state.
- When every task passes, continue to the assessment.
