My requirement is that i want to write an SQL query that does monthwise *report*. For example from webGUI , when i select on the dropdown for month as DEC and select year as 2010 . I need to create show the sum of DUR,VIEWS and AMOUNT from 1st of November 2010 to 1st of December 2010.Any Ideas on how to do it.
The result for DEC2010 should be like below
**DEC2010 12 19 341**

Answer 1

this would work (although of course due to your requirement the first day of november will be in both the november and december monthly reports ?!):
SQL> VARIABLE p_months VARCHAR2(3);
SQL> VARIABLE p_year NUMBER;
SQL> EXEC :p_months := 'DEC'; :p_year := 2010;
PL/SQL procedure successfully completed.
SQL> WITH tableA AS (
2 SELECT DATE '2010-10-23's_date , 12 dur, 1 views, 10000.0 amount FROM DUAL
3 UNION ALL SELECT DATE '2010-11-01', 2, 4 , 200.0 FROM DUAL
4 UNION ALL SELECT DATE '2010-11-14', 4, 5 , -9 FROM DUAL
5 UNION ALL SELECT DATE '2010-12-01', 6, 10, 150.0 FROM DUAL
6 UNION ALL SELECT DATE '2010-12-19', 1, 12, 130.0 FROM DUAL
7 )
8 SELECT :p_months||:p_year month,
9 SUM(dur),
10 SUM(views),
11 SUM(amount)
12 FROM tableA
13 WHERE s_date >= add_months(to_date(:p_months||:p_year, 'MONYYYY'), -1)
14 AND s_date < to_date(:p_months||:p_year, 'MONYYYY') + 1;
MONTH SUM(DUR) SUM(VIEWS) SUM(AMOUNT)

DEC2010 12 19 341
