What's the purpose of all these conversions? What's the CREATE_TIME data type - a DATE? If so, you are converting a DATE to a VARCHAR2 and then immediately back to DATE (without specifying the parsing mask,) which makes no sense. The conversion should actually be on the other side:

V$CASE_MASTER.CREATE_TIME >= TO_DATE('01/01/2008','DD/MM/YYYY') AND V$CASE_MASTER.CREATE_TIME <= TO_DATE('30/09/2008','DD/MM/YYYY')
