Folks,
Is there a much better way of writing the following SQL statement, bearing in mind the performace hits due to the use of functions in the GROUP BY and ORDER BY clauses?
SELECT TO_CHAR(TEST_DATE, 'MON RRRR') XXX, count(*)
FROM TBL_XYZ
WHERE TEST_VAL = DECODE(:P_VALUE, 'BEGIN', 'B', 'END', 'E')
AND TEST_DATE BETWEEN :P_START_DATE AND :P_END_DATE
GROUP BY TO_CHAR(TEST_DATE, 'MON RRRR')
ORDER BY TO_DATE('01 '||XXX);
Thanks.
