Question

我在我的客户端 - 服务器应用程序中使用了嵌入式数据库H2。

对于某些目的，我需要创建用户，只能在没有权限的情况下查看表来更改它们。我认为创建非管理员用户足以满足我的需求。但是我尝试执行查询SELECT * FROM ADDRESS时遇到以下异常：

org.h2.jdbc.JdbcSQLException: Недостаточно прав на объект "PUBLIC.ADDRESS"
Not enough rights for object "PUBLIC.ADDRESS"; SQL statement:
SELECT * FROM ADDRESS [90096-164]

有没有办法实现这个目标？

您必须向所创建的用户授予选择权。
