我有一个应该使用 SymmetricDS 同步的数据库。有以下查询，建立基础：

CREATE TABLE `defectstdreference` (
  `std_doc_id` bigint(20) NOT NULL COMMENT 'Идентификатор НТД',
  `improve_notice_doc_id` bigint(20) NOT NULL COMMENT 'Идентификатор предписания',
  `defect_id` int(11) NOT NULL COMMENT 'Идентификатор дефекта',
  `paragraph` varchar(4000) NOT NULL COMMENT 'Пункт НТД',
  `reference_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'Идентификатор ссылки на пункт НТД',
  `client_id` bigint(20) DEFAULT NULL,
  PRIMARY KEY (`reference_id`),
  KEY `Relationship70` (`std_doc_id`),
  KEY `Relationship72` (`improve_notice_doc_id`,`defect_id`,`client_id`),
  CONSTRAINT `Relationship70` FOREIGN KEY (`std_doc_id`) REFERENCES `std` (`doc_id`) ON DELETE NO ACTION ON UPDATE NO ACTION,
  CONSTRAINT `Relationship72` FOREIGN KEY (`improve_notice_doc_id`, `defect_id`, `client_id`) REFERENCES `improvementnoticedefect` (`doc_id`, `defect_id`, `client_id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=17 DEFAULT CHARSET=utf8 COMMENT='Ссылки на НТД выявленных нарушений';

以及引用的表格：

CREATE TABLE `improvementnoticedefect` (
  `description` varchar(20000) NOT NULL COMMENT 'Описание нарушения',
  `defect_id` int(11) NOT NULL COMMENT 'Номер нарушения в рамках предписания',
  `doc_id` bigint(20) NOT NULL COMMENT 'Номер документа "Предписание"',
  `client_id` bigint(20) NOT NULL,
  PRIMARY KEY (`doc_id`,`defect_id`,`client_id`),
  KEY `Relationship68` (`doc_id`,`client_id`),
  CONSTRAINT `Relationship68` FOREIGN KEY (`doc_id`, `client_id`) REFERENCES `improvementnotice` (`doc_id`, `client_id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Дефект';

如您所见，表的主键impovementnoticedefect和 fk 约束 72 中的列顺序defectstdreference是相同的。

然而，当同步开始时，SymmetricDS 给了我错误：

Cannot add foreign key constraint.  Failed to execute: ALTER TABLE `defectstdreference`
    ADD CONSTRAINT `Relationship72` FOREIGN KEY (`improve_notice_doc_id`, `defect_id`, `client_id`) REFERENCES `improvementnoticedefect` (`doc_id`, `defect_id`, `client_id`)

当我尝试为创建的表 SymmetricDS 转储 sql 时，我得到以下信息：

CREATE TABLE `improvementnoticedefect` (
  `defect_id` int(11) NOT NULL,
  `doc_id` bigint(20) NOT NULL,
  `client_id` bigint(20) NOT NULL,
  `description` varchar(20000) NOT NULL,
  PRIMARY KEY (`defect_id`,`doc_id`,`client_id`),
  KEY `Relationship68` (`doc_id`,`client_id`),
  CONSTRAINT `Relationship68` FOREIGN KEY (`doc_id`, `client_id`) REFERENCES `improvementnotice` (`doc_id`, `client_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

如您所见，主键中字段的顺序是不同的。

我尝试手动运行错误的查询，它给出了一个错误，但是当我更改字段的顺序时，一切都很好。

我怎样才能解决这个问题？有什么我应该做的配置吗？我在这里真的很绝望，有人可以帮忙吗？

更新 我已经意识到，问题在于 SymmetricDS 使用 XML 发送表，而 PK 是从 XML 创建的：

<!DOCTYPE database SYSTEM "http://db.apache.org/torque/dtd/database">
<database name="dataextractor">
    <table name="improvementnoticedefect">
         <column name="defect_id" primaryKey="true" required="true" type="INTEGER" size="10">
             <platform-column name="mysql" type="INT" size="10"/>
         </column>
         <column name="doc_id" primaryKey="true" required="true" type="BIGINT" size="19">
             <platform-column name="mysql" type="BIGINT" size="19"/>
         </column>
         <column name="client_id" primaryKey="true" required="true" type="BIGINT" size="19">
             <platform-column name="mysql" type="BIGINT" size="19"/>
         </column>
         <column name="description" required="true" type="VARCHAR" size="20000">
             <platform-column name="mysql" type="VARCHAR" size="20000"/>
         </column>
         <foreign-key name="Relationship68" foreignTable="improvementnotice">
             <reference local="doc_id" foreign="doc_id"/>
             <reference local="client_id" foreign="client_id"/>
         </foreign-key>
     </table>
</database>

你可以看到，这个 XML 主键是按照创建列的顺序生成的，这实际上是错误的
