MySQL數據庫把查詢結果拼接成字符串

GROUP_CONCAT()函數

示例：(SELECT GROUP_CONCAT(`Name`) FROM `product_propmap` WHERE `Flag`=0  and `ParentId`=1 and `ProductId`=obj.`Id`) AS Surface

還可以用distinct

示例：(SELECT GROUP_CONCAT(distinct(`Name`) ) FROM `product_propmap` WHERE `Flag`=0  and `ParentId`=1 and `ProductId`=obj.`Id`) AS Surface
