Chinna,

Your question is very vague.
Do you have a table which has a date column and do you want to extract Mondays from those values
or
in general from calendar view?

Yet I guess this select will help you achieve if you change it according to your needs.

The following SQL extracts all Mondays in the date range mentioned in the where clause.

select * from sys_calendar.calendar where day_of_week=2 and calendar_date between date -77 and date
order by 1;

Hope this serves your question.

try:
select calendar_date
from sys_calendar.calendar
where day_of_week=2
and year_of_calendar = 2007
order by 1;
