Question

我想将所有的表名保存为小写。示例person
我使用Liquibase设置我的数据库，它看起来像

http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.1.xsd“＆GT; 添加人员表

我使用H2数据库来运行我的集成测试并在pom.xml中设置为

   <cargo.datasource.datasource.earth>
        cargo.datasource.driver=${h2.driver}|
        cargo.datasource.url=${datasource.url}|
        cargo.datasource.jndi=${datasource.jndi}|
        cargo.datasource.username=${h2.user}|
        cargo.datasource.password=${h2.user}
    </cargo.datasource.datasource.earth>

datasource.url看起来像

<datasource.url>jdbc:h2:${project.build.directory}/earth;DATABASE_TO_UPPER=false</datasource.url>

当我运行mvn时，我看到了

正如您所看到的，liquibase创建了person表，我使用了DATABASE_TO_UPPER=false H2从PERSON到Person

问题
如何判断H2我的表格全部是小写的 - ＆gt; person和不 Person？

Answer 1

尝试在H2连接URL设置＆＃34; database_to_upper = false＆＃34;中使用。

Answer 2

在 h2 连接 URL 中使用 DATABASE_TO_LOWER=TRUE。示例：

url: jdbc:h2:mem:testdb;MODE=PostgreSQL;DATABASE_TO_LOWER=TRUE;CASE_INSENSITIVE_IDENTIFIERS=TRUE;
