Please help me in writing the SQL

Question

Hi,
I am new to oracle.. Can you please help me in writing a SQL
I have a table which has the following columns
Start_date m1 ---- Start month of each quarter (Jan,Apr,Jul,oct)
end_date m3---- End month of each quarter
m1_start_date,
m1_end_date,
m2_start_date,
m2_end_date,
m3_start_date,
m3_end_date,
M1_act_rev,
m2_act_rev,
m3_act_rev
If a user selects the dates from Jan,2011 to Jun, 2011
I should get the aggregate of the revenues (m1+m2+m3+m1+m2+m3)

Answer 1

Hi Gurus,
Will this work
select
b.DISTRICT_NAME,
count(c.CONTRACT_NUMBER),
sum(C.M1_ACT_REV),
sum(C.M2_ACT_REV),
sum(C.M3_ACT_REV),
sum(C.M1_EXP_PRICE),
sum(C.M2_EXP_PRICE),
sum(C.M3_EXP_PRICE)
from
clm_mn_compliance_data c,
CLM_MN_CUSTOMER_ALIGNMENT_DATA b
where
((m1_start_date between '01-01-2011' and '03-31-2011' ) and (m1_end_date between '01-01-2011' and '03-31-2011')) or
((m2_start_date between '01-01-2011' and '03-31-2011' ) and (m3_end_date between '01-01-2011' and '03-31-2011')) or
((m3_start_date between '01-01-2011' and '03-31-2011' ) and (m3_end_date between '01-01-2011' and '03-31-2011')) and
b.CUSTOMER_ID = C.CUST_CTRT_ID
group by
B.DISTRICT_NAME;
