MySQL 触发器的多个 if 子句

Question

我想达到这样的目标：

当插入数据时，它将检查日期列，将其与当前日期进行比较，并将某些内容写入另一列。示例：

Today 27/08/2018
Date 27/08/2018
Result: Same Day

Today 27/08/2018
Date 26/08/2018
Result: Before Today

Today 27/08/2018
Date 28/08/2018
Result: After Today

我试过了，还是不行：

//CREATE TRIGGER trigger_update_status_before_insert 
BEFORE INSERT 
ON tablex
FOR EACH ROW BEGIN
  IF (NEW.date < CURDATE()) THEN
        SET NEW.status = 'Before Today'
  END IF

  IF (NEW.date = CURDATE()) THEN
        SET NEW.status = 'Same Day'
  END IF

  IF (NEW.date > CURDATE()) THEN
        SET NEW.status = 'After Today'
  END IF
END;//

error in your SQL syntax creating MySQL trigger @p.campbell 的回答解决了这个问题。我刚刚删除了半列，它起作用了。
