Mysql搜索查询按品牌和总和品牌价值排序

Hi I am trying to run a query where brand_name should be distinct but the brand_value show sum. Mysql TABLE structure with Primary key

betbingo 1 www.abc.com
betbingo 1 www.abc.com
betbingo 2 www.abc.com
bestbingo 2 www.abc.com
bestbingo 1 www.abc.com
bet365 1 www.abc.com

I want brand column distinct and show sum of 2nd column. So the result should be like this

Betbingo 4 www.abc.com
bestbingo 3 www.abc.com
bet365 1 www.abc.com

I am using While loop in php
Can you please help me out.
Thanks

Use group by clause. It will select distinct brand name from your table.

select brand, sum(2nd column) from your_table group by brand

Hope it will help.

Not clear about the primary key but group by and sum() in the sql should do the trick

Select brand , sum(brand_value) as sum_of_brandvalue from tablename group by brand ;
