Question 3
How many inner queries can be contained within a nested subquery?
1 point
- 361
- Unlimited
- 10
Solution
Break Down the Problem
- Identify the nature of the question, which relates to the limitations of nested subqueries in SQL.
- Understand the options provided: 361, Unlimited, 10.
Relevant Concepts
- In SQL, subqueries (or inner queries) can be nested within other queries. However, most SQL databases impose limits on how many levels of nested queries are allowed.
- Commonly, databases like MySQL allow a substantial number of nested queries, often around 60 or more, while others may comfortably allow for potentially more, depending on the specific implementation.
Analysis and Detail
- The key aspect to focus on is how many inner queries can sit within a nested subquery.
- If we consider typical databases and their handling of subqueries, while the upper limit may be quite high, "unlimited" is generally not a feasible answer as practical limitations exist due to performance reasons and SQL standards.
Verify and Summarize
- Given the options, "Unlimited" does not accurately reflect the nature of SQL constraints.
- The most appropriate and logical choice, based on standard observations and practices across various SQL databases, would suggest a realistic upper threshold.
Final Answer
The best response to the question is Unlimited, although practical limits exist, the theoretical answer in many database systems suggests no fixed cap is defined.
