2. Having Clause
• The HAVING clause is like WHERE but operates
on grouped records returned by a GROUP BY.
• HAVING applies to summarized group records,
whereas WHERE applies to individual records.
• Only the groups that meet the HAVING criteria will
be returned.
4. “Why we use Having Clause”
• It's not always that we will want to perform
groupings on all the data in a given table.
• There will be times when we will want to
restrict our results to a certain given
criteria. In such cases , we can use the HAVING
clause
