Question

我已经使用MySQLWorkbench设计了模式并在下面生成了创建SQL。

此查询通过此错误：无法创建表'museum.statue_details'。有人可以告诉我什么似乎是问题，如何解决？感谢。

Answer 1

您有许多具有相同名称的约束，更改它们或让mysql命名它们。

CONSTRAINT `artefact_id`

这无处不在。还有其他人。同样在museum.creator中你缺少列：

 CONSTRAINT `epoch_id`
    FOREIGN KEY ()
    REFERENCES `museum`.`epoch` ()

你可能想要介于epoch_id之间。所有这些都是固定的，它在我的机器上运行。

Answer 2

你应该给出你的外键的其他名称：

而不是

CONSTRAINT `artefact_id`
FOREIGN KEY (`artefact_id`)
REFERENCES `museum`.`artefact` (`artefact_id`)

做的：

CONSTRAINT FK_mykey  --> give name as you like here to distinguich between others
FOREIGN KEY (`artefact_id`) 
REFERENCES `artefact` (`artefact_id`)

Answer 3

创建表语法：

http://dev.mysql.com/doc/refman/5.7/en/create-table.html

我认为问题在于您使用{name1}声明表名。{name2}。

CREATE TABLE IF NOT EXISTS `collection` (
  `collection_id` INT NOT NULL,
  `name` VARCHAR(45) NULL,
  `type` VARCHAR(45) NULL,
  `description` VARCHAR(45) NULL,
  `address` VARCHAR(45) NULL,
  `phone` VARCHAR(45) NULL,
  `current_contact_person` VARCHAR(45) NULL,
  PRIMARY KEY (`collection_id`),
  UNIQUE INDEX `name_UNIQUE` (`name` ASC))
ENGINE = InnoDB;

`
