来自正向工程 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

我从我的正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；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，以便在 ' CONSTRAINT fk_Employees_EmployeeTitle1 FOREIGN KEY (`EmployeeTitle_EmpT' at line 9

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，但我不知道从哪里开始让它工作.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

这个错误是因为MySQL和MariaDB不兼容造成的.

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

这个脚本显然是用于 MySQL 的，但它是在 MariaDB 上运行的.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.现在很多人认为 MariaDB 更先进，但事实是它们现在到处都有小/大的差异.

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;

用途:

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(针对 MariaDB)不需要 VISIBLE，因为索引在 MariaDB 中默认可见.

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