关于H2的任何想法(Oracle模式)"语法错误:SELECT NEXTVAL FROM [*] DUAL"？

Question

在Oracle模式下使用H2(v1.3.154)时出现以下错误:

<bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.h2.Driver" />
        <property name="url" value="jdbc:h2:mem:testdb;MODE=Oracle" />
        <property name="username" value="sa" />
        <property name="password" value="" />
</bean>

和hibernate v3.5.6的Oracle方言:

hibernate.dialect=org.hibernate.dialect.Oracle10gDialect

错误 :

Caused by: org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement "SELECT 
SQ_PERSON_ID.NEXTVAL FROM[*] DUAL "; expected "identifier"; SQL statement:

知道发生了什么,我的配置错过了什么？我找到了这篇文章并尝试了补丁,它没有解决错误.谢谢你的帮助 !

Answer 1

请确保创建序列.如果它被创建,那么它适用于我:

create sequence SQ_PERSON_ID;
select SQ_PERSON_ID.nextval from dual;

如果未创建,则会抛出相同的错误消息.

Answer 2

我正在使用 Oracle 模式处理 h2，但上面提到的所有上述解决方案对我都不起作用。虽然经过一些研究，我发现这个查询可以很好地获取序列中的下一个值。

select nextval('SchemaName', 'SequenceName');
