我的触发看起来是这样的: begin
IF ((NEW.tgebucht >= NEW.tteilnmax) AND (NEW.tgebucht!=0) AND (OLD.tstatus=0)) THEN
SET NEW.tstatus = 1;
ELSEIF ((NEW.tgebucht < NEW.tteilnmax) AND (OLD.tstatus=1)) THEN
我有这样的代码: import java.util.Scanner;
public class DecimalPoints {
/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
Scanner scann
我有这样的代码(很基本的): #include <iostream>
#include <iomanip>
using namespace std;
int main()
{
float a = 0.0,
b = 0.0,
c = 0.0;
cout<<"Input a: ";
cin>>a;
cout<<"input b: ";
cin>>b;
c
