Question

我希望制作一个通过商店程序操作的表格。我有2个程序可以选择和更新。第一个完美地执行，但最后一个有问题。它肯定感觉像mysql解析器问题。我希望我能在这里找到一些帮助，因为项目即将推出。运行第二个sp后，无论是通过SP还是基本查询，每个后续更新语句都会失败，直到我删除该记录为止;然后我可以再次插入然后通过基本查询调用更新。我需要使用SP，因为我正在与运行NodeJS的Web服务器进行通信。我正在使用node-mysql包。我使用的是mysql-5.7。

SECOND SP ERROR：错误代码：1109未知表＆＃39;消费者＆＃39;在字段列表中

谢谢， timecatcher

我很抱歉。我的触发器文件是1500行代码。我通过调用CONSUMER.loggedIn在触发器中犯了一个错误。谢谢你的时间
