Hello All
Is it possible to run a count on cells that have values only eg

I have the following table

PC TD
1 34
1 35
2 36
2 NULL
3 NULL
3 NULL

I would like to run a query to get the following back

PC COUNT
1 2
2 1
3 NULL

Is this possible?

Thanks

Paul

[code]
select PC, count(TD)
from table
group by PC
[/code]

You want PC 3 Count 0 to show as NULL ?
