Question

I need to use a SQL statement that is bound to a Gridview & needs to be something like

SELECT * from Table Sum(Column1) AS S00, (S00/CONSTANT) AS C01 or

SELECT * from Table Sum(Column1) AS S00, Sum(Column1) / CONSTANT AS C01

CONSTANT will be a value passed to the query as a session variable.

i.e the 2nd column of the Gridview is calculated from the result of 1st calculation.

What will be the best way to achieve this?

Answer 1

You’ll need to repeat the expression, or use a subquery e.g.

SELECT *, C01 = (S00/Constant) 
FROM
(
 SELECT S00 = SUM(Column1)
  FROM table
) AS x;
