could not execute statement

请帮助我使用本准则，因为我无法理解为什么我会收到此"could not execute statement" error.

我尝试了很多东西，但都没有奏效。有些文章甚至建议使用@cascade = {cascadeType = SAVE_UPDATE}，但我不想将我的表链接到任何其他表。我应该只在代码中维护所有关系。必须有某种方法可以保存表（如果与其他表无关）。请帮忙。

1 个答案:

答案 0 :(得分：1)

请尝试为您的实体实现Serializable接口（尽管这不是Hibernate强加的）。同时将_BankBranchContactId重命名为id。并启用hibernate_sql日志记录以查看触发的sql查询。还要检查是否正确创建了模式“stserptest”。
