hi ,
here are the details
CURRENT_MONTH is date datatype in PLAYER_MONTHLY_SUMMARY table TO_DATE, as the name implies, converts something TO a DATE . If current_month is already a DATE, you don't need to convert it to a date.
Besides, the 1st argument to TO_DATE is supposed to be a VARCHAR2. Don't use a DATE where a VARCHAR2 is expected.
and date range is from next_run_date where my next_strt_date and next_end_date both are date datatype
instead of this below query
(TO_DATE(PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH, 'DD-MON-YYYY') BETWEEN
TO_DATE('01-MAR-2012', 'DD-MON-YYYY') AND
TO_DATE('31-MAR-2012', 'DD-MON-YYYY')
if i try below one then it worked
PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH BETWEEN
TO_DATE('01-MAR-2012', 'DD-MON-YYYY') AND
TO_DATE('31-MAR-2012', 'DD-MON-YYYY')
is this approach is rightYes, that's comparing a DATE (current_month) to other DATEs (the results of TO_DATE).
Remember that all DATEs in Oracle include hours, minutes and seconds. If the hours, minutes and seconds of current_month are always 00:00:00 (for example, if current_month is always populated with TRUNC (some_date, 'MONTH')) then the comparison above is okay. But if current_month can be something like 6:52;31 on March 31, 2012, then it will fail the condition, becuase the upper end of the range is
TO_DATE('31-MAR-2012', 'DD-MON-YYYY') which is 00:00:00 on March 31, 2012. To include current_month that is any time of day on March 31, you'd have to do something slightly diferent, such as
PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH  BETWEEN TO_DATE ( '01-MAR-2012'     -- Default time, 00:00:00, is okay here
                                                , 'DD-MON-YYYY'
                          AND     TO_DATE ( '31-MAR-2012 23:59:59'
                                                , 'DD-MON-YYYY hh24:mi:ss'
                                    ) or
     PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH  >= TO_DATE ( '01-MAR-2012', 'DD-MON-YYYY')
AND  PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH  <  TO_DATE ( '31-MAR-2012', 'DD-MON-YYYY') + 1
