前向工程EERD的Workbench 8.0中的错误代码1064

标签： mariadb mysql-workbench

我从前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；请查看与您的MariaDB服务器版本相对应的手册以获取正确的语法，以在'CONSTRAINT fk_Employees_EmployeeTitle1 FOREIGN KEY（第9行的`EmployeeTitle_EmpT'附近使用

代码对我来说看起来不错，我也不知道从哪里可以使它正常工作。代码如下：

该错误是由于MySQL和MariaDB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分歧。许多人认为MariaDB现在更先进了，但事实是，他们现在在各地之间存在小/大差异。

在这种情况下，创建索引时，MariaDB不支持关键字VISIBLE。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;

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),
  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，因为默认情况下索引在MariaDB中可见。
