所以，我有一张更新患者的表格。状态根据他们最新提交的信息。在每天结束时，我检查患者当天是否完成了治疗，根据这些结果，我填写一张表格，然后向患者发送电子邮件（如果他们正在接受治疗），或他们的照顾者（如果他们不是）。
在我们为看护人提供电子邮件之前，我使用的是计算参与度的每日存储过程，以及用于汇总相关消息的连接查询。它看起来像这样：
DELIMITER $$

**我正在努力修复将所有行更新为3的故障，而不仅仅是那些获取消息的人，但这并不是什么大问题，因为患者设置的每个新输入都检查= 0，然后那天（d0）将它设置回1，所以检查基本上是一个衡量我知道过程是否顺利进行的指标。
现在，我们需要添加护理人员，并将他们的电子邮件CONCAT放入一个字段（以减少发送的电子邮件数量），我尝试通过逐行计算引入光标以使程序更精确（我稍后会必须为每一行添加更多计算），但光标在第一个UPDATE（d0count）后停止。但是，如果我删除了那个UPDATE查询，那么它只完成第一个IF语句或CASE（两个都尝试过），然后在没有进入其他情况下的行的情况下关闭：

任何和所有帮助将不胜感激！与此同时，我通过运行两个单独的程序来修补它。第一个计算天数，第二个计算消息。我可以在一个过程中完成所有操作吗？或者，运行这些计算的最有效和最精确的方法是什么。
谢谢！
