I was trying to create a view.
I got it working now.
Thanks a lot guys...
select count(dns_name) as units_completed_today,
count(distinct store_number) as stores_completed_today,
(select count(distinct store_number) from asda.stores where scheduled_on = '2004-07-07') as stores_scheduled_today,
(select count(dns_name) from asda.dns_names where replaced ='Yes' and serviced = '2004-07-07') as units_replaced_today,
(select count(distinct store_number) from asda.dns_names where serviced is not NULL ) as total_stores_completed,
(select count(dns_name) from asda.dns_names where serviced is not NULL) as total_units_completed,
(select count(dns_name) from asda.dns_names where replaced = 'Yes') as total_units_replaced
from asda.dns_names
where serviced = '2004-07-07'
