我有以下问题。

我有由转储创建的包含代码的 sql 文件：

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */;
/*!40103 SET TIME_ZONE='+00:00' */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

/*SOME MORE SCRIPTS*/

DROP TABLE IF EXISTS `avalues`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;

CREATE TABLE `avalues` (

我正在使用InnoDB引擎。

在我拥有 mysql 版本5.6.5-m8-log之前，一切正常，并且所有脚本都已使用 mysql 正确处理。

今天我将 mysql 更新到5.7.9-log版本，当我想运行这些脚本时，不会创建表 avalues。

我收到以下错误： 错误代码：1215 无法添加外键约束

当我从脚本行中取出

FULLTEXT KEY `I_AVALUES_VALUE_FULLTEXT` (`AVALUES_VALUE`)

或两条线

, CONSTRAINT `FK_AVALUES_MVALUES_ID` FOREIGN KEY (`AVALUES_MVALUES_ID`) REFERENCES `mask_values` (`MVALUES_ID`) ON DELETE CASCADE
, CONSTRAINT `FK_AVALUES_OBJECT_ID` FOREIGN KEY (`AVALUES_OBJECT_ID`) REFERENCES `object` (`OBJECT_ID`) ON DELETE CASCADE

表已正确创建。但似乎如果所有三行都在一起，则会导致提到的错误。

我已经读过，在 mysql 5.6 版之前，这两个键（外文和全文）不能放在一个表中。但我使用的是 mysql 版本 5.7.9。我试图用谷歌搜索问题，但我找不到适合我的解决方案。

感谢你的回答

这是一个错误：错误 #78955：使用 InnoDB 全文索引和约束导入转储失败

尝试以下更改，首先创建引用的表：

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */;

/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;

当您在创建表后尝试SHOW ENGINE INNODB STATUS（参见13.7.5.15 SHOW ENGINE 语法）时，您可以阅读以下内容：
