What is the difference between HAVING clause and the WHERE clause?..

Answer / mayursinh zala

'Where' clause applies to the individual rows whereas 'Having' clause is used to test some condition on the group(usually aggregate methods) rather than on individual rows.

Specifies a search condition for a group or an aggregate. HAVING can be used only with the SELECT statement. HAVING is typically used in a GROUP BY clause. When GROUP BY is not used, HAVING behaves like a WHERE clause.

So you can use having WITHOUT group by clause. This is a sample, although it might make no sense of business value:


select max(state) from States having count(State) > 60
