H2：如何设置默认架构和数据库？

我正在使用Liquibase进行数据库更新并针对H2进行测试.

我使用Spring来配置属性.我用

dataSource.setUrl("jdbc:h2:mem:test_common");

连接到test_common数据库,但它没有工作.

我意识到在H2数据库中！= Schema,所以我试图将一个默认模式放到test_common中

dataSource.setUrl("jdbc:h2:mem:test_common;INIT=CREATE SCHEMA test_common\\; SET SCHEMA test_common");

但这没有用,我把日志视为

如何在H2中设置默认架构和数据库名称？

最佳答案

默认架构是PUBLIC

为了记录,SET SCHEMA命令的H2数据库站点的SQL Grammar页面说：

The default schema for new connections is PUBLIC.

该文档还指出您可以在连接时指定默认架构：

This setting can be appended to the database URL: jdbc:h2:test;SCHEMA=ABC

只有一个数据库

至于访问各种数据库,H2不支持CLUSTER或CATALOG的sql标准概念.您作为JDBC URL的一部分连接到一个特定的数据库(目录).与该数据库的连接仅限于该单个数据库.请参阅问题,Can you create multiple catalogs in H2?以及Thomas Mueller的答案.

您可以打开另一个与另一个数据库的连接但它完全是分开的.

因此,谈论“默认数据库”与H2数据库没有任何意义.
