SQL interview Question and Answers #2 on Where Clause vs Having Clause
One of the most frequent questions asked in the data analyst or business analyst interviews is the difference between Where clause and Having clause. The idea of the interviewer is to understand whether the candidate knows the basics right and knows how to use these while writing queries.
Where Clause is very important as you always want to look at the most relevant data based on your use case and the where clause allows you to filter the rows based on your conditions.
While Having clause is slightly different. It is mainly used along with the aggregate functions such as min(), max(), avg() etc. Having clause allows us to filter out the final result based on aggregate functions.
