Question

I want to do something like this in SQL Server:

SELECT
    pt.quantity AS 'QTY'
    ,[QTY] * 5
 FROM
 product pt

But here I am getting error:
Invalid column name ‘QTY’.

Please suggest what could be the issue OR a possible workaround.

Thanks,
Justin Samuel.

Answer 1

i think this will also work

SELECT
    quantity AS 'QTY'
    ,quantity  * 5
 FROM
 product

you can try this also

SELECT QTY,QTY * 5 FROM 
(
 SELECT
        quantity AS 'QTY'   
     FROM
     product) Productstable
