with this normal query of delete

delete from table where condition-'a';

will it work in table data are present from year 2014.
i want to delete all data starting from 2014 to till now.

and Connor said...

You need *something* in that table that tells you what year the data was inserted.

If it was (say) a DATE column you could do something like

delete from table
where my_date_col >= date '01-01-2014'
and my_date_col < date '01-01-2015'


but there is nothing internally stored in the database which indicates the time at which data was created.
