小菜,请教个SQL查询问题
产品表:products
产品订单表:orders_products产品:products 表结构
products_id products_title
1 时尚长裙
2 时尚短裙
产品订单:orders_products表结构
orders_id products_id
1 1
2 1
3 2
需求:根据关键字(时尚)查询,并按产品热卖程度排序(统计订单表中产品进行排序)。
请问SQL要怎样写呢,亲们。
------解决方案--------------------
select a.products_id,a.products_title,count(*) as num
from products A inner join orders_products B
on A.products_id = B.products_id where instr(a.products_title,'时尚')>0
group by a.products_id,a.products_title
order by num desc
------解决方案--------------------
SQL code
select p.products_id ,p.products_title ,count(*) as num
from products p,orders_products o
where p.products_id=o.products_id
group by p.products_id ,p.products_title
order by 3 desc
