Question

开始时问题仅与H2数据库有关。在其他数据库（MySQL）上它可以正常工作而没有问题。

由（jHipster）生成的配置：

解决方法：

<changeSet author="newbie" id="1449941926339-4">
    <addPrimaryKey columnNames="disease_id, descent_descent_of_disease"
                   constraintName="PRIMARY_DISEASE_DESCENTS"
                   tableName="DISEASE_DESCENTS"/>
</changeSet>

<changeSet author="newbie" id="1449941926339-5">
    <addPrimaryKey columnNames="descent_of_disease"
                   constraintName="PRIMARY_ENUM_DESCENT"
                   tableName="ENUM_DESCENT"/>
</changeSet>

MySQL: Creating table with two foreign keys fails with “Duplicate key name” error

Answer 1

如果在创建表后添加主键liquibase将使用<changeSet author="newbie" id="1449941926339-1"> <createTable tableName="ENUM_DESCENT"> <column name="descent_of_disease" type="VARCHAR(255)"> <constraints nullable="false"/> <constraints primaryKey="true"/> </column> </createTable> </changeSet>。并且您不能使用相同名称的多个约束。所以H2报告错误。

您已找到解决方法。

也许另一种方法是将主键定义添加到create table语句中：

CREATE TABLE...

然后将在PRIMARY KEY语句中处理主键定义。

（顺便说一句：这在mySQL上不会发生，因为mySQL能够在ALTER TABLE...语句中使用addPrimaryKey。所以使用mySQL DB liquibase会将你的ALTER TABLE... ADD PRIMARY KEY...变更集翻译成类似width:100%;）

Liquibase主键在H2上创建两次
