Ora-00907 error

Question

My query is like this :--
select * from incident inc
inner join injuryincident inj on inc.docid=inj.docid where
inc.incdate = (1=decode( :date1 ,null,1,0) or inc.incdate= :date1)
while if it is other field except date it is working fine. Kindly suggest me

Answer 1

SELECT INCDATE
FROM incident
WHERE INCDATE between (1=decode( :date1 ,null,1,0)
) or TO_DATE(:date1,'dd-mm-yyyy')) AND (1=decode(
:date2 ,null,1,0) or TO_DATE(:date2,'dd-mm-yyyy'))
i have tried this also i am getting same errorI would code it as follows, choose a minimum and maximum date where you can be sure that your actual dates are in between
SELECT INCDATE
FROM   incident
WHERE  INCDATE between TO_DATE(NVL(:date1, '01-01-1900'),'dd-mm-yyyy') AND TO_DATE(NVL(:date2, '31-12-2999'),'dd-mm-yyyy')Message was edited by:
