select
cd_gender,
cd_marital_status,

cd_purchase_estimate,
count(*) cnt2,
cd_credit_rating,
count(*) cnt3,
c.c_customer_sk
from
customer c,customer_address ca,customer_demographics
where
c.c_current_addr_sk = ca.ca_address_sk and
ca_state in ('KY','GA','NM') and
cd_demo_sk = c.c_current_cdemo_sk
group by cd_gender,
cd_marital_status,
cd_education_status,
cd_purchase_estimate,
cd_credit_rating,
c_customer_sk
order by cd_gender,
cd_marital_status,
cd_education_status,
cd_purchase_estimate,
cd_credit_rating,
c_customer_sk;
select a.cd_gender, a.cd_marital_status, a.cd_education_status, a.cnt1,
a.cd_purchase_estimate, a.cnt2, a.cd_credit_rating, a.cnt3
