Explain HAVING Clause in SQL ?

The HAVING clause is used in combination with the GROUP BY clause. It can be used in a SELECT statement to filter the records that a GROUP BY returns.



SELECT column(n) FROM table_name

WHERE [ conditions ]

GROUP BY column(n) HAVING  conditions ORDER BY column(n)

When WHERE, GROUP BY and HAVING clauses are used together in a SELECT statement, the WHERE clause is processed first, then the rows that are returned after the WHERE clause is executed are grouped based on the GROUP BY clause.
