查询两张关联表信息，原sql：

SELECT * FROM  car_life_info c

left JOIN shop_label sl

ON  c.shop_id = sl.shop_id

出现重复 店铺名称

合并 后面列label

新sql：

SELECT c.*,group_concat(sl.label_id) label_ids ,group_concat(l.label_name ) label_names
FROM car_life_info c
LEFT JOIN shop_label sl
ON c.shop_id = sl.shop_id
LEFT JOIN label l
ON sl.label_id = l.label_id
group by shop_id

问题解决！
