> In the following SQL, drill cribs when trying to convert a number which is in varchar
>        select cast (case IsNumeric(Delta_Radio_Delay)  
> when 0 then 0 else Delta_Radio_Delay end as BIGINT) 
> from datasource.`./sometable` 
> where Delta_Radio_Delay='4294967294';
> BIGINT should be able to take very large number. I dont understand how it throws the
below error:
>     0: jdbc:drill:> select cast (case IsNumeric(Delta_Radio_Delay)  
>     when 0 then 0 else Delta_Radio_Delay end as BIGINT) 
>     from datasource.`./sometable`

> [Error Id: a63bb113-271f-4d8b-8194-2c9728543200 on cluster-3:31010] (state=,code=0)
> How can i modify SQL to fix this?
