SQL HAVING Clause Interview Questions

HAVING questions test your ability to filter aggregated data, a critical skill that goes beyond basic GROUP BY.

Expect questions combining GROUP BY, aggregates (SUM, COUNT, AVG), and HAVING conditions.

Interviewers evaluate whether you understand the difference between WHERE and HAVING, and proper ordering of clauses.

SQL HAVING Clause Interview FAQs

What is the difference between WHERE and HAVING?

WHERE filters individual rows before aggregation occurs. HAVING filters groups after aggregation. You use WHERE to exclude rows from being aggregated, and HAVING to exclude groups from the final result.

Can you use HAVING without GROUP BY?

Some databases allow it, treating the entire result set as one group. However, this is generally considered non-standard and not recommended. Always pair HAVING with GROUP BY for clarity and portability.
