Make sure that as per Cast criteria string data should not come.

Hi,

Try this....

SQL

SELECT
CASE WHEN length(translate(substr(T_BILLSUMMARY.OPDNUMBER,1,6),' +-.0123456789',' ')) > 0 
THEN 'Wrong Value'
ELSE cast(substr(T_BILLSUMMARY.OPDNUMBER,1,6) as INTEGER) 
END 
as OPD,
substr(T_BILLSUMMARY.OPDNUMBER,8,12) as OPDYEAR,
T_BILLSUMMARY.BILLTONAME
FROM T_BILLSUMMARY
where cast(substr(T_BILLSUMMARY.OPDNUMBER,1,6) as NUMBER)=10805;

Hope this will help you.

Cheers

If required use no as char.
