Try This:
select to_char(to_date(start_date,'DD-MON-YYYY'), 'DD-MON-YYYY')
from table_name
order by to_date(start_date,'DD-MON-YYYY') asc
Question
I have start_date column in a table of type varchar.eg.,
GridSQL -> select start_date,count(*) from table_name group by start_date order by start_date asc;
start_date

15-MAY-2011
16-JUN-2011
19-JUN-2011
description of table_name is..
GridSQL -> describe table_name;
COLUMN_NAME SQL_DATA_TYPE TYPE_NAME IS_NULLABLE KEY
----------------------------------------------------------------------
start_date 12 VARCHAR(1024) YES NO
A_partynumber 12 VARCHAR(100) YES NO
i need an query that works in GridSQL to convert the start_date into date format and sort as date wise.For that i used some queries but not worked.eg.,
GridSQL -> select to_date(start_date,'DD-MON-YYYY') from table_name group by to_date(start_date,'DD-MON-YYYY');
to_date
-----------------------
2010-02-05 00:00:00.0
2011-06-19 00:00:00.0
2011-05-15 00:00:00.0
2011-06-16 00:00:00.0
2011-04-13 00:00:00.0
2011-05-14 00:00:00.0
2011-05-13 00:00:00.0
2011-02-11 00:00:00.0
2011-04-15 00:00:00.0
2011-04-14 00:00:00.0
here date with time is coming and format of date is completely changed.i need date as 05-FEB-2010 and it is giving 2010-02-05 00:00:00.0
so what i am expecting is this
start_date
------------------------
05-FEB-2010
