求前多少个自然数之和不超过5000的程序，怎样吖，吾该sql

begin

declare @sum int, @cnt int;

declare @sign int;

set @cnt = 0; set @sign = 0; set @sum = 0;

while(1 = 1)
begin

set @cnt = @cnt + 1;

set @sum = @sum + @cnt;

if(@sum > 5000)
begin

set @sign = @cnt - 1;
break;

end

end

select '自然数'=@sign;

end

public class Test {
public static void main() {
int sum = 0;
int i = 0;
while(sum <= 5000 ) {
sum += i;
i++
}
System.out.println(i);
}
}
