SELECT Distinct *
from Customer_Details
Left Outer join EMAS
on Customer_Details.street_name = EMAS.street_name
Left Outer join work_orders
on Customer_Details.ID = work_orders.customer_ID
where Proceed_Retrofit = 'yes'
what is street name?
i gues this is where the "duplicates" arise...
do you not have a proper key to this table..?
