如果我使用DB Owner连接到DB，请成功选择语句return
resultset
。我不明白
GRANT
语句中缺少了什么。

简单地说，这是一个问题，因为根据规范，SQL标识符应该折叠为大写。因此，如果没有双引号，
testuser
将变成
testuser
，这并不限于Derby。Oracle、FirebirdDB和其他公司也遵循同样的行为（顺便说一句，PostgreSQL折叠成小写，MySQL保留大小写，所以这可能是造成混淆的部分原因）

在支持SQL的数据库中，案例折叠是一个特别麻烦的领域，因为实际上很少有人喜欢标准的强制行为（正如PostgreSQL团队所说，这是无法挽回的破坏），因此项目可以在几乎没有人喜欢的行为和非标准的行为之间进行选择。

这是一个区分大小写的问题吗？您是否确实将select授予TESTUSER，但您是作为TESTUSER连接到数据库的？尝试执行另一个grant语句，确保在引号中指定testuser，这样您将授予全小写testuser:“grant select on test.user_info to“testuser””Bryan再次保存我谢谢：）我真的不习惯Derby中的这种区分大小写的方法。如果您还记得，我在
connectionURL
中对用户名提出了类似的要求。无论如何
stmt2.execute（“将SELECT ON TABLE TEST.USER\u信息授予”+“\”“+user1+”\”）工作正常。你可以写作为答案。
