mariadb - 来自正向工程 EERD 的 Workbench 8.0 中的错误代码 1064

Question

我从我的正向工程数据库中收到以下错误：

错误代码：1064。您的 SQL 语法有错误；检查与您的 MariaDB 服务器版本相对应的手册，以在“约束fk_Employees_EmployeeTitle1 外键”附近使用正确的语法（第 9 行的“EmployeeTitle_EmpT”

代码对我来说看起来不错，但我不知道从哪里开始让它工作。代码如下：

该错误是由于 MySQL 和 MariaDB 之间的不兼容引起的。

该脚本显然适用于 MySQL，但它在 MariaDB 上运行。尽管 MariaDB 最初与 MySQL 100% 兼容，但现在两个数据库已经出现了分歧。许多人现在认为 MariaDB 更先进，但事实是它们现在到处都有小/大的差异。

在这种情况下，创建索引时，VISIBLEMariaDB 不支持该关键字。而不是使用：

CREATE TABLE IF NOT EXISTS `A2Lewis`.`Employees` (
  `empID` INT NOT NULL,
  `empFirst` VARCHAR(45) NULL,
  `empLast` VARCHAR(45) NULL,
  `empWage` DECIMAL(4,2) NULL,
  `empPhone` CHAR(10) NULL,
  `EmployeeTitle_EmpTitleID` INT NOT NULL,
  PRIMARY KEY (`empID`),
  INDEX `fk_Employees_EmployeeTitle1_idx` (`EmployeeTitle_EmpTitleID` ASC) VISIBLE,
  CONSTRAINT `fk_Employees_EmployeeTitle1`
    FOREIGN KEY (`EmployeeTitle_EmpTitleID`)
    REFERENCES `A2Lewis`.`EmployeeTitle` (`EmpTitleID`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

利用：

CREATE TABLE IF NOT EXISTS `A2Lewis`.`Employees` (
  `empID` INT NOT NULL,
  `empFirst` VARCHAR(45) NULL,
  `empLast` VARCHAR(45) NULL,
  `empWage` DECIMAL(4,2) NULL,
  `empPhone` CHAR(10) NULL,
  `EmployeeTitle_EmpTitleID` INT NOT NULL,
  PRIMARY KEY (`empID`),
  INDEX `fk_Employees_EmployeeTitle1_idx` (`EmployeeTitle_EmpTitleID` ASC),
  CONSTRAINT `fk_Employees_EmployeeTitle1`
    FOREIGN KEY (`EmployeeTitle_EmpTitleID`)
    REFERENCES `A2Lewis`.`EmployeeTitle` (`EmpTitleID`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

第二个查询（对于 MariaDB）不需要，VISIBLE因为索引在 MariaDB 中默认是可见的。
