I have this query:
select distinct emplid,BIRTHDATE,
TO_DATE((TO_CHAR(SYSDATE,'YYYY')||TO_CHAR(BIRTHDATE,'MMDD')),'YYYYMMDD')
FROM PS_PERSONAL_DATA C
WHERE BIRTHDATE IS NOT NULL
and TO_DATE((TO_CHAR(SYSDATE,'YYYY')||TO_CHAR(BIRTHDATE,'MMDD')),'YYYYMMDD') BETWEEN SYSDATE-30 and (SYSDATE)
birthdate is of date type.
I get the message error ORA-01839 date not valid for month specified. I can avoid this by removing the DISTINCT clause but i need it. please help, thanks
