Liquibase: How to Set Foreign Key(s) Constraint in Column Tag?
gradle, java, liquibase
Solution
Use a nested `<constraints>` tag in your column tag.
Example:
<changeSet id="SAMPLE_1" author="alice">
<createTable tableName="employee">
<column name="id" type="int" autoIncrement="true">
<constraints primaryKey="true"/>
</column>
<column name="first_name" type="varchar(255)"/>
<column name="last_name" type="varchar(255)">
<constraints nullable="false"/>
</column>
</createTable>
</changeSet>
<changeSet id="create address table" author="bob">
<createTable tableName="address">
<column name="id" type="int" autoIncrement="true">
<constraints primaryKey="true"/>
</column>
<column name="line1" type="varchar(255)">
<constraints nullable="false"/>
</column>
<column name="line2" type="varchar(255)"/>
<column name="city" type="varchar(100)">
<constraints nullable="false"/>
</column>
<column name="employee_id" type="int">
<constraints nullable="false" foreignKeyName="fk_address_employee" references="employee(id)"/>
</column>
</createTable>
</changeSet>
Problem
How can I configure foreign keys through column tag attributes `foreignKeyName` and `references`? The only example I've found demonstrates how to add foreign keys after the fact.
