Hi,
I am new to H2 database, I ran into a particular problem where I was
running a function named format.
public static String format(Double sumValue,Integer decimalValue){
if(sumValue==null)
return null;
else{
//format in particular order.
}
}
There are chances of sumValue getting null value.
when I am running a query it is throwing a following exception
SELECT format(commamount,2) as formatted FROM pshipcommdetail

I went through the documentation and was able to figure out that the
aruguments should be of wrapper class hence I changed to Double but it
didnt work!
Can anyone of you please help me to figure out where the actual
problem is?
Thanking you
