7 years ago Well, we need check for this not in udf initialization function but inside implementation function. Exactly saying where we convert string to longlong using std::stol() if this string can not be converted, there should be some message for this. Could you try to implement this?
if (((longlong)args->args[0]) > 20) { my_stpcpy(message,"Factorial function can't calculate numbers more than 20"); return 1; }
