Hello All,

I m facing problem in one query. What I did is

SELECT
PRODUCT_ID,
PRODUCT_END_DATE,
CASE
WHEN PRODUCT_ID = 1 THEN DATEADD(YY,-5,PRODUCT_END_DATE)
WHEN PRODUCT_ID = 2 THEN DATEADD(YY,-10,PRODUCT_END_DATE)
WHEN PRODUCT_ID = 3 THEN DATEADD(YY,-15,PRODUCT_END_DATE)
END AS MODIFIED_END_DATE
FROM PRODUCTS
WHERE MODIFIED_END_DATE BETWEEN '2008-04-01' AND '2008-04-30'

when I execute this query returns an error as
Invalid column name MODIFIED_END_DATE

So how can I write this query? any idea.

Thanks in advance.

Also note that you cant use alias name directly anywhere other than ORDER BY Clause if you dont use derived table
