Question : sql question

I have this section in my sql script:
ISNULL(lot_loc.unit_cost, item.avg_u_cost) as [Unit Cost]

it works very well but in some cases lot_loc also = 0.0 in which case I'd also like it to pull the value from item.avg_u_cost.

How can I do this?

Answer : sql question

use this instead of the above

case when lot_loc.unit_cost is null or lot_loc.unit_cost =0 then item.avg_u_cost ELSE lot_loc.unit_cost  END as as [Unit Cost]
