The document discusses the HAVING clause in SQL, which operates on grouped records returned by a GROUP BY clause, allowing only groups that meet the specified criteria to be returned. It notes that HAVING applies to summarized group records whereas WHERE applies to individual records, and provides an example syntax using SELECT, FROM, WHERE, GROUP BY, and HAVING. The purpose of the HAVING clause is to restrict groupings to those meeting certain criteria, like when not wanting to perform groupings on all table data.

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

Syntax
SELECT function(column_Name)
FROM TableName
