everymonth admin will refresh actual data table and automatically this above table will update with unique seq_no and process_date.
I need to extarct min date of everymonth(First refresh of last 6 months - excluding currrent month) and also seq_no related to that month so using joins(using seq_no - that is available in main table) i can combine actual data.
I need result like:
02-MAR-13 731 ( I don't need MAR as it should not take current month data)
so i need final result like below:
02-FEB-13 726
05-JAN-13 722
08-DEC-12 718
03-NOV-12 713
05-OCT-12 709
01-SEP-12 704
