>>>>>>A SELECT statement doing this is interesting. Just curious what would happen if the closing stock consists of 2 purchases, ie. purchase of 10 @ 12.50 and another purchase of 10 @ 13.00. Out of which only 5 are sold @ whatever rate. Now the closing stock is 15 out of which 5 is @ 12.50 and 10 is @ 13.00.

>Thanks, may be Tariq needs a similar algorithm. I think we also are using similar approach, but not sure where exactly. I know my colleague mentioned FIFO term and I think he intended to assign me this, but don't know what happened with that "project".

:) you can have a head-start now when the project comes back to you, best of luck
