用于显示按类别收到的最新产品的MySQL Qery [英] MySQL Qery for Displaying Latest Product's Received by Category

问题描述

大家好！



你能帮我解决一下查询数据库记录的问题吗？



这是场景..



我正在开发一个库存系统，它包括使用datagrid的报告和视图。我有产品，产品类别，接收等。我想按类别创建最新收到的产品的视图，其中至少有三个。我的问题是我对它进行了查询，并使用了mysql的LIMIT函数。



我需要帮助进行数据库查询，这至少会导致按类别收到的三种最新产品。 （结果每个类别必须至少显示三种产品）。





谢谢....
