A search condition can be used in various SQL clauses such as WHERE, ON, QUALIFY, RESET WHEN, or HAVING.
When used in a HAVING clause, a logical expression can be used with an aggregate operator.
For example, the following query uses a search condition in a HAVING clause to select from the Employee table those departments with the number 100, 300, 500, or 600, and with a salary average of at least $35,000 but not more than $55,000:
SELECT AVG(Salary) FROM Employee WHERE DeptNo IN (100,300,500,600) GROUP BY DeptNo HAVING AVG(Salary) BETWEEN 35000 AND 55000 ;
