Answer 1

hi Vinay,
DT_DATE DATE(7)
In my table all this fields are stored like this format *04/22/2009 12:00:00 AM*
my java parmeter give rptdate=*29/04/2009* as java string
Query
SELECT IN_TOTCHLD
FROM PLSDTA_DTLS_TB
WHERE TO_DATE(DT_DATE,'DD-MM-YYYY') BETWEEN
(CASE WHEN TO_CHAR(to_date(rptdate,'DD-MM-YYYY'),'MM') <=3 THEN
TO_DATE('01-04-' || TO_CHAR(rptdate,'YYYY') - 1,'DD-MM-YYYY')
ELSE TO_DATE('01-04-' || TO_CHAR(rptdate,'YYYY'),'DD-MM-YYYY')
END)
AND TO_DATE(rptdate,'DD-MM-YYYY')
yet it gives error at
TO_DATE('01-04-' || TO_CHAR(rptdate,'YYYY') - 1,'DD-MM-YYYY')
ELSE TO_DATE('01-04-' || TO_CHAR(rptdate,'YYYY'),'DD-MM-YYYY')
above 2 lines.
