Question

我一直在尝试导入我在数据库上创建的转储文件，该数据库包含服务器MariaDB版本10.1.9上的虚拟列表。这是.sql文件的一部分：

DROP TABLE IF EXISTS `abc`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `abc` (
`a` int(11) DEFAULT NULL,
`b` int(11) AS ((`a` + 1)) VIRTUAL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
-- Dumping data for table `abc`
LOCK TABLES `abc` WRITE;
/*!40000 ALTER TABLE `abc` DISABLE KEYS */;
INSERT INTO `abc` VALUES (2,3),(3,4),(3,4),(56,57);
/*!40000 ALTER TABLE `abc` ENABLE KEYS */;
UNLOCK TABLES;

既然MySQL最新版本支持虚拟列，我预计导入会成功，但它没有给出错误：

Error Code: 3105 - The value specified for generated column 'b' in table 'abc' is not allowed.

有什么办法可以避免这个错误？我可以将转储文件导入到数据到MySQL服务器版本5.7.11 ??

我已经检查了版本10.1.10，这很好用。我首先使用您的CREATE创建了表，然后我将其转储并导入它。
