【问题描述】：

我已经用 mysql workbench 创建了一个模型，每次我想执行 sql 文件时都会遇到这个错误

ERROR 1064 (42000) at line 55 in file: 'D:\db.sql': 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，以获取在 ' 附近使用的正确语法 约束fk_customer_order_customer1 外键 (customer_id) ' 在第 8 行

ERROR 1064 (42000) at line 76 in file: 'D:\db.sql': You have an error in your SQL syntax;检查与您的 MariaDB 服务器版本相对应的手册，以获取在 ' 附近使用的正确语法 约束fk_product_category 外键 (category_id) REFERENC' 在第 9 行

ERROR 1064 (42000) at line 98 in file: 'D:\db.sql': You have an error in your SQL syntax;检查与您的 MariaDB 服务器版本相对应的手册，以获取在 ' 附近使用的正确语法 索引fk_ordered_product_product (customer_order_id ASC) 可见， 第 6 行的 CONST'

这是为我生成的代码mysql工作台

重复的重复***.com/questions/53480613/…

MariaDB Table Creation Error with Foreign Key的可能重复

【参考方案1】：

删除关键字VISIBLE。 （它只是 在“附近”文本之前。）

【讨论】：

谢谢这对我有用，其他解决方案没有

VISIBLE 是一个非常新的关键字；这是默认设置。 Workbench 似乎太急于不必要地包含它。正如您所发现的，它不应该这样做，因为它会导致向后不兼容。
