Question

我正在尝试在phpMyAdmin中创建关系型MySQL数据库。基本的表结构如下：

productsTbl：

ID（主键，int，11），名称（varchar，20）， ColourID（int，02）

coloursTbl：

ID（主键，int 11），颜色（varchar，20）

我正在尝试在coloursTbl中的ID和producsTbl中的ColourID之间的设计选项卡上创建关系，但是我收到以下错误：

我遇到了同样的问题并使用以下步骤进行了纠正：

1）转到产品表

2）转到结构

3）在ColourID列上单击索引

4）回去创建关系

这将解决您的问题
