建议您仔细查看标识符的区分大小写. DataNucleus用如下一行记录JDBC驱动程序所允许的内容

Suggest you look closer at case-sensitivity of your identifiers. DataNucleus logs what the JDBC driver allows with a line like

支持的标识符大小写:"MixedCase"大写"MixedCase-Sensitive"

Supported Identifier Cases : "MixedCase" UPPERCASE "MixedCase-Sensitive"

因此它可能需要大写字母或引用模式(所有RDBMS都是不同的，包括某些RDBMS，这取决于它们所运行的操作系统)

so possibly it requires the schema in UPPERCASE or maybe quoted (all RDBMS are different, and inclusive some differ depending on the operating system they're running on)

显然不建议在注释中嵌入特定于数据存储的信息.

Obviously embedding datastore-specific info in annotations is not recommended.
