Mysql 在相同条件下更新多个字段（如果或情况）

我需要一些帮助。这里有一些关于这个主题的问题和答案，但没有找到一个适合我需要的

我有两个疑问：

UPDATE leilaov
   SET seconds = CASE
      WHEN (mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini = HOUR(NOW()) AND minutoini <= MINUTE(NOW())) 
        OR (mesini = MONTH(NOW()) AND diaini < DAYOFMONTH(NOW())) 
        OR (mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini < HOUR(NOW()))
        OR (mesini < MONTH(NOW())) THEN seconds-1
   END
WHERE numero12345 = 1


UPDATE leilaov
   SET seconds = IF((mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini = HOUR(NOW()) AND minutoini <= MINUTE(NOW())) 
                OR (mesini = MONTH(NOW()) AND diaini < DAYOFMONTH(NOW())) 
                OR (mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini < HOUR(NOW()))
                OR (mesini < MONTH(NOW())), seconds-1, seconds)
WHERE numero12345 = 1

更新leilaov
设置秒数=大小写
不幸的是，当（mesini=MONTH（NOW（））和diaini=DAYOFMONTH（NOW（））以及horaini=HOUR（NOW（））和minutoini时，您需要为尝试设置的每个字段重复您的案例。因此，您需要执行以下操作：

UPDATE leilaov
   SET seconds = CASE
      WHEN (mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini = HOUR(NOW()) AND minutoini <= MINUTE(NOW())) 
        OR (mesini = MONTH(NOW()) AND diaini < DAYOFMONTH(NOW())) 
        OR (mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini < HOUR(NOW()))
        OR (mesini < MONTH(NOW())) THEN seconds-1
   END,
, second_field = CASE
          WHEN (mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini = HOUR(NOW()) AND minutoini <= MINUTE(NOW())) 
            OR (mesini = MONTH(NOW()) AND diaini < DAYOFMONTH(NOW())) 
            OR (mesini = MONTH(NOW()) AND diaini = DAYOFMONTH(NOW()) AND horaini < HOUR(NOW()))
            OR (mesini < MONTH(NOW())) THEN seconds-1
       END

WHERE numero12345 = 1

当（mesini=MONTH（NOW（））和diaini=DAYOFMONTH（NOW（））和horaini=HOUR（NOW（））时minutoini感谢@Dany Caissy。关于你对表格结构的评论，不幸的是，它被继承了。再次感谢@Dany Caissy。你对表格结构的评论让我想，为什么我会理所当然地认为我继承了什么？猜猜看，我重建了那个结构，编码现在更短、更容易、更可读，而且，作为奖励，p表现也更好。；）酷，别忘了向上投票或接受你喜欢的答案。再次你好@Dany Caissy！天哪！！！我在这方面真的是个新手。我在哪里或如何向上投票？我的答案左上角有一个“向上”和一个“向下”箭头，在“0”附近。你也可以选择接受附近的答案。
