MySQLWorkbench正向工程错误

Question

我正在 MySql Workbench 8.0 中处理一个模型，当我单击正向工程并尝试生成我得到的模型的脚本时

Executing SQL script in server
ERROR: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VISIBLE,
  CONSTRAINT `fk_Compras_Personas`
    FOREIGN KEY (`persona_id`)
    R' at line 9
SQL Code:
        -- -----------------------------------------------------
        -- Table `bd_inventario2018_2`.`compras`
        -- -----------------------------------------------------
        CREATE TABLE IF NOT EXISTS `bd_inventario2018_2`.`compras` (
          `nmcompra` INT(11) NOT NULL,
          `persona_id` INT(11) NOT NULL,
          `fecompra` DATE NOT NULL,
          PRIMARY KEY (`nmcompra`, `persona_id`),
          INDEX `fk_Compras_Personas_idx` (`persona_id` ASC) VISIBLE,
          CONSTRAINT `fk_Compras_Personas`
            FOREIGN KEY (`persona_id`)
            REFERENCES `bd_inventario2018_2`.`personas` (`id`)
            ON DELETE NO ACTION
            ON UPDATE NO ACTION)
        ENGINE = InnoDB
        DEFAULT CHARACTER SET = utf8

SQL script execution finished: statements: 6 succeeded, 1 failed

Fetching back view definitions in final form.
Nothing to fetch

或者当我尝试同步我得到的模型时

Executing SQL script in server
ERROR: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VISIBLE' at line 4
SQL Code:
        ALTER TABLE `bd_inventario2018_2`.`productos` 
        ADD COLUMN `anchetas_id` INT(11) NOT NULL AFTER `psventa`,
        ADD COLUMN `productoscol` VARCHAR(45) NOT NULL AFTER `anchetas_id`,
        ADD INDEX `fk_productos_Anchetas1_idx` (`anchetas_id` ASC) VISIBLE

SQL script execution finished: statements: 3 succeeded, 1 failed

Fetching back view definitions in final form.
Nothing to fetch

有人知道发生了什么事吗？这是一个自动过程，我不会覆盖任何内容，

谢谢

MySQL Workbench 正在为您可能没有的 MySQL 8(它支持新的不可见索引)生成脚本。

您需要在 Model\Model Options\MySQL\Target MySQL Version 中或全局地在 Edit\Preferences\Modelling\MySQL\Target 中指定您正在使用的 MySQL 版本MySQL 版本.
