初始化时在H2数据库中设置别名

Question

我从生产代码中命名了查询，它使用 Oracles

SUBSTR()

方法。我怎样才能让这些电话与 H2s

SUBSTRING()

一起工作？

我正在尝试使用 H2 进行测试。我创建了

hibernate.cfg.xml

的副本并对其进行了更改，以便它连接到 H2 数据库。

hibernate.cfg.xml

引用一些

*.hbm.xml

文件，其中一些包含命名查询，使用 Oracles

SUBSTR()

.

我看过

CREATE ALIAS

（http://h2database.com/html/commands.html#create_alias）的文档，但想不出如何让它足够早地工作，以便新命令是甚至在 Hibernate 初始化期间可用。

如何在 hibernates 初始化时尽早定义别名，以便此错误消息消失？
