Hi,

Both HAVING and WHERE clause used for specifying the search condition in SQL queries.

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. Having Clause is basically used only with the GROUP BY function in a query.

WHERE Clause can be used for specifying the search criteria in SELECT, DELETE, UPDATE statements.

Thanks,
