java - HSQLDB:java.sql.SQLSyntaxErrorException:用户缺少权限或找不到对象

Question

我发现这个错误在整个互联网上出现过很多次，但我还没有找到适合我的案例的解决方案。我有一个 HSQL 数据库 - 我已成功连接到数据库中的一个表。我继续在数据库中创建另一个表 - 根据需要修改完全相同的 Java 代码，但它会引发错误:java.sql.SQLSyntaxErrorException:用户缺少权限或找不到对象:USER。

我发现在我的文件存储脚本中有用于创建 PRODUCT 表的代码，但是我创建 USER 表的方式与创建 PRODUCT 表的方式相同 - 使用 HSQL 数据库管理器。

这是我的错误代码:

我不确定这是访问权限问题还是它无法识别 USER 表的存在 - 我创建了一种方法来显示数据库中的所有表名，它确实显示了 PRODUCT 而不是 USER。有什么解决这个问题的建议吗？

我希望我已经提供了足够的信息 - 如果需要任何进一步的信息，请告诉我，我非常感谢您提供的任何帮助。

Answer 1

如果您实际创建了一个名为 USER 的表，它将与其他表一起显示在 .script 文件中。

您可能在稍后的 session 中创建了表，但没有关闭数据库或执行 CHECKPOINT，因此未保存额外的 CREATE TABLE USER ... 语句。
