I have a column in TableA which contains date as Varchar2 datatype for column Start_date.( '2011-09-17:09:46:13').
Now what i need to do is , compare the Start_date of TableA with the SYSDATE, and list out any values thts atmost 7days older than SYSDATE.
Can any body help me with this isssue.
You may perform the below to check the date:
select * from
TableA
where
to_date(start_date,'YYYY-MM-DD') between sysdate and sysdate-7;
