what is difference between where clause and having clause?
Answer Posted / anto padma sheela
1. Having clause is usually used with Group By clause
although it can be used without it too.
2. 'Having' is just an additional filter to 'Where' clause.
3. '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.
