来自前向工程 EERD 的 Workbench 8.0 中的错误代码 1064 [英] Error Code 1064 in Workbench 8.0 from forward engineered EERD

问题描述

我从前向工程数据库中收到以下错误:

I get the following error from my forward engineered database:

错误代码:1064.您的SQL语法有错误；请参见.检查与您的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"

Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ' CONSTRAINT fk_Employees_EmployeeTitle1 FOREIGN KEY (`EmployeeTitle_EmpT' at line 9

代码对我来说看起来不错，我也不知道从哪里可以开始使用它.代码如下:

The code looks good to me and I have no idea where to go from here to make it work. The code is as follows:

推荐答案

该错误是由于MySQL与MariaDB不兼容而引起的.

The error is caused because of incompatibility between MySQL and MariaDB.

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，但现在两个数据库都出现了分歧.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.

This script is apparently for MySQL, but it's run on MariaDB. Even though MariaDB was originally 100% compatible with MySQL both databases have now diverged. Many people consider MariaDB more advanced now, but that fact is they now have small/big differences here and there.

在这种情况下，创建索引时，MariaDB不支持关键字 VISIBLE .而不是使用:

In this case, when creating an index, the keyword VISIBLE is not supported by MariaDB. Instead of using:

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.

The second query (for MariaDB) does not require VISIBLE since indexes are visible by default in MariaDB.
