A dаtа аnalyst writes this SQL tо identify stоres that had mоre than $10,000 in sales last month: WITH monthly_sales AS ( SELECT store_id, SUM(sale_amount) AS total_sales FROM sales WHERE sale_date BETWEEN '2023-07-01' AND '2023-07-31' GROUP BY store_id ) SELECT store_id FROM monthly_sales WHERE total_sales > 10000; What is the function of the monthly_sales CTE? OPTIONS:A. It updates the sales table with monthly totalsB. It stores only the store IDs that had more than $10,000 in salesC. It creates an intermediate table to simplify calculating and filtering monthly salesD. It acts as a subquery that persists across multiple queries ANSWER:C EXPLANATION:The CTE helps modularize the query: it handles filtering and aggregation, and then the outer query filters further. It doesn’t update data (A), doesn’t apply the $10,000 filter itself (B), and it doesn’t persist beyond the query (D).
