Question

我使用liquibase 3.5.5和postgresql。我的所有表都是在指定的模式中创建的，但是当liquibase尝试生成DDL时，它会附加＆＃34; public。＆＃34;在referencesTableName前面。我试过制作表名＆＃34; identity.users＆＃34;，但它只是试图创建公共。＆＃34; identity.users＆＃34;。

例如，下面的

<createTable tableName="users" schemaName="identity">
            <column name="id" type="bigint" defaultValueSequenceNext="seq_users">
                <constraints primaryKey="true" primaryKeyName="pk_users"/>
            </column>
</createTable>
<createTable tableName="external_identities" schemaName="identity">
            <column name="id" type="bigint" defaultValueSequenceNext="seq_external_identities">
                <constraints primaryKey="true" primaryKeyName="pk_external_identities"/>
            </column>
            <column name="user_id" type="bigint">
                <constraints foreignKeyName="fk_external_identities_users" referencedTableName="users" referencedColumnNames="id" nullable="false"/>
            </column>
</createTable>

制作：

 CREATE TABLE identity.external_identities (id BIGINT DEFAULT nextval('identity.seq_external_identities') NOT NULL, user_id BIGINT NOT NULL, CONSTRAINT fk_external_identities_users FOREIGN KEY (user_id) REFERENCES public.users(id))

文档帮助不大，XSD文件不会将模式列为选项：

<!-- Attributes for constraints -->
    <xsd:attributeGroup name="constraintsAttributes">
        <xsd:attribute name="nullable" type="booleanExp" />
        <xsd:attribute name="primaryKey" type="booleanExp" />
        <xsd:attribute name="primaryKeyName" type="xsd:string" />
        <xsd:attribute name="primaryKeyTablespace" type="xsd:string" />
        <xsd:attribute name="unique" type="booleanExp" />
        <xsd:attribute name="uniqueConstraintName" type="xsd:string" />
        <xsd:attribute name="references" type="xsd:string" />
        <xsd:attribute name="referencedTableName" type="xsd:string"/>
        <xsd:attribute name="referencedColumnNames" type="xsd:string"/>
        <xsd:attribute name="foreignKeyName" type="xsd:string" />
        <xsd:attribute name="deleteCascade" type="booleanExp" />
        <xsd:attribute name="deferrable" type="booleanExp" />
        <xsd:attribute name="initiallyDeferred" type="booleanExp" />
        <xsd:attribute name="checkConstraint" type="xsd:string" />
    </xsd:attributeGroup>

Answer 1

必须将changeSet与sql一起使用： ALTER TABLE schema.table ADD CONSTRAINT约束FOREIGN KEY（fk_field）参考schema.ref_table（field）

Answer 2

尝试使用单独的changeset添加外键constratint。它将是addForeignKeyConstraint。它具有架构属性。

ChangeSet将如下所示：

<changeSet author="liquibase-docs" id="addForeignKeyConstraint-example">
    <addForeignKeyConstraint
            baseColumnNames="user_id"
            baseTableName="external_identities"
            constraintName="fk_external_identities_users"
            referencedColumnNames="id"
            referencedTableName="users"
            baseTableSchemaName="identity"
            referencedTableSchemaName="identity"/>
</changeSet>
