Is this a homework question? Having is used with grouping. What exactly do you need though?

Solution 2

XML

Because we can not use Where clause with <b>aggregate functions </b>like <b>count(),min(), sum()</b> etc. so <b>having clause</b> came into existence to overcome this problem in sql. see example for having clause go through this link

Solution 1

Having works with Group by and aggregate function. And where you can use in direct column.

For Example:

SQL

SELECT Item_Code,Item_Description,UOM
FROM Products
WHERE Item_Description like '%book%'
GROUP BY Item_Code,Item_Description,UOM
HAVING UOM = 'Each'

Hope this will help..
