我不知道它是什么，因为它从未发生在我身上。我被困在这个问题上，所以我提前感谢你的一些建议。

【问题讨论】：

标题似乎与内部错误无关。你正在执行什么 SQL 语句？
我认为是“插入 INTO”，我的 BPM 会自动完成！

标签： java mysql

【解决方案1】：

就像错误状态：

Caused by: java.sql.BatchUpdateException: Duplicate entry '242-243' for key 'PRIMARY'

您正在尝试插入一个与现有主键相同的值 ('242-243')。主键是唯一的，不能有任何重复。

【讨论】：

感谢您的回复，但我想确定调用了哪个表！
我们无权访问您的代码。您需要检查哪一行正在抛出它并使用调试器或打印，检查正在执行的命令。
哦，好吧，我告诉你更多：它只发生在下午 4 点，在我调试的那一刻，我似乎清晰而正确。所以这不是 MySQL 的错？
故障在于向MySQL插入数据的命令

【解决方案2】：

BlueMoon93 的回答是正确的。但是，找出受此影响的表的一种方法是使用分析器。此主题由 question 和答案涵盖。

一般来说，分析器既可用于性能检查，也可用于查看正在运行的查询、过程等。第二个选项需要它，所以this 可能是一个很好的起点。
