A lоgistics аnаlyst writes а SQL query using a CTE called LateDeliveries tо isоlate shipments that missed their delivery window. She later tries to reference LateDeliveries in a separate query but encounters an error. What best explains why? OPTIONS:A. The CTE wasn't defined as a viewB. CTEs can only be used in recursive queriesC. CTEs are temporary and only exist within the query in which they're definedD. The database doesn't support joins on CTEs ANSWER:C EXPLANATION:CTEs are temporary and scoped to a single query—they cannot be referenced across multiple queries like a permanent view or table. This is a key limitation that often surprises beginners. Option A is a common confusion, but CTEs are not intended to persist like views. Options B and D are incorrect: CTEs are not limited to recursion and can be used in joins.
