1. What is SQL?

   1. A tool for designing user interfaces
   2. A type of artificial intelligence model
   3. A method for storing files in the cloud
   4. A programming language used to communicate with databases

2. What advantage does AI have when it comes to writing SQL?

   1. AI replaces the need for any database software
   2. AI is fluent in SQL and can translate natural language requests into queries
   3. AI automatically fixes hardware problems in databases
   4. AI can physically touch the database server

3. Before running an AI-generated SQL query on your actual database with real data, what should you do?

   1. Test it on a separate test database first
   2. Delete your database backups for safety
   3. Run it three times to make sure
   4. Ask the AI to promise it will work

4. You want to find users who haven't placed an order in 30 days. What information would you need to provide AI to get an accurate SQL query?

   1. The exact names of your users and orders tables, the relevant column names (like user_id, order_date), and the data types used
   2. Nothing - AI already knows your database
   3. Just the table names
   4. The number of rows in each table

5. What are aggregations in SQL?

   1. Functions that perform calculations across multiple rows to produce summary results like counts, sums, or averages
   2. A method for backing up tables
   3. A type of database index
   4. A way to connect two databases together

6. Why might the same logical query look different in MySQL versus PostgreSQL?

   1. Because they store data differently on disk
   2. Because these are different database systems with slightly different SQL syntax and features
   3. Because MySQL is older than PostgreSQL
   4. Because one uses AI and the other doesn't

7. What does it mean to optimize a slow SQL query?

   1. Rewriting the query to run faster while returning the same results, often by using indexes or restructuring the logic
   2. Making the database server faster
   3. Deleting half the data to reduce workload
   4. Running the query more frequently

8. If you ask AI for a query to get the 'top 10 users by total order value last month,' what must exist in your database for this to work?

   1. A users table, an orders table, and columns tracking user IDs, order amounts, and order dates
   2. A pre-calculated ranking table
   3. A table containing only the top 10 users
   4. A special AI-enabled database

9. What is a practical benefit of asking AI to explain JOIN types using your actual tables?

   1. It converts your data to a different format
   2. It creates new tables in your database
   3. It can show you exactly how each type of join would affect your specific data
   4. It makes your database run faster

10. What could happen if you use a vague description of your database schema when asking AI for SQL?

    1. The generated query might reference column or table names that don't actually exist in your database
    2. The database will automatically fix any errors
    3. The query will automatically optimize itself
    4. The AI will refuse to generate anything

11. What is the purpose of a WHERE clause in a SQL query?

    1. To filter rows based on specified conditions so only matching records are returned
    2. To create a new table
    3. To sort the results alphabetically
    4. To connect multiple tables together

12. What type of query would you use to calculate the average order value for each customer?

    1. A query that deletes old records
    2. A query using GROUP BY with the AVG aggregation function
    3. A query that creates a new table
    4. A simple SELECT statement with no modifications

13. In the context of databases, what is a 'test database'?

    1. A separate database environment used to safely try out queries without affecting real data
    2. A database that automatically fixes errors
    3. A database that only contains test data
    4. A smaller version of a database used for training

14. What does it mean to 'trace the logic' of a SQL query?

    1. To run the query multiple times
    2. To follow each step of the query's execution in your mind to understand how it arrives at its results
    3. To write comments in the query
    4. To copy the query to another database

15. What is a JOIN in SQL used for?

    1. To create a new database
    2. To delete duplicate records
    3. To compress database files
    4. To combine data from two or more tables based on related columns
