Hi,
This may be of help.
Remember Pointless has made a point ;) (worth millions)
If possible , DO NOT store dates as strings or numbers.Let dates be dates.
WITH dat AS
(SELECT ' THIS IS JAN' x,to_char(to_date('01-JAN-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS FEB' x,to_char(to_date('01-FEB-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS MAR' x,to_char(to_date('01-MAR-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS APR' x,to_char(to_date('01-APR-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS MAY' x,to_char(to_date('01-MAY-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS JUN' x,to_char(to_date('01-JUN-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS JUL' x,to_char(to_date('01-JUL-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS AUG' x,to_char(to_date('01-AUG-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS SEP' x,to_char(to_date('01-SEP-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS OCT' x,to_char(to_date('01-OCT-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual UNION
SELECT ' THIS IS NOV' x,to_char(to_date('01-NOV-2009','DD-MON-YYYY'),'mon/yyyy') y FROM dual)
SELECT * FROM dat
WHERE to_date(y,'mon/yyyy') BETWEEN to_date('01 jan 2009','dd mon yyyy') AND to_date('01 mar 2009','dd mon yyyy')Cheers!!!
