Select Maths

Hi again,

Same SELECT query as before, different area of it. I have a function that
calculates the recommended purchase order quantity for a stock item based
off various other values and functions:

pqty(stock.code) AS "pqty"

This needs to be rounded up / down to the nearest multiple of the purchase
unit quantity for that product - It's Friday afternoon and my head has
refused to help me work out the maths all afternoon!

Example:

Pqty = 60

Purchase Unit = 25

Pqty needs to be rounded down to 50.

I guess I'm also asking if I should do this in the Pqty function or in the
SELECT query to optimize the result?

Thanks all - Enjoy your weekends I hope!

Cheers,

-p
