MYSQL查询中的垂直总计

Question

如果我可以使用此查询 -

SELECT country,
SUM(IF(product= 'product1', 1,0)) AS `product1`, 
SUM(IF(product= 'product2', 1,0)) AS `product2`, 
SUM(IF(product= 'product3', 1,0)) AS `product3`, 
SUM(IF(product= 'product4', 1,0)) AS `product4`, 
SUM(IF(product= 'product5', 1,0)) AS `product5`, 
COUNT(*) AS total FROM table
group by country 

给我一​​个这样的结果 -

        Product 1    Product 2    Product 3     Total    etc...
France        103           99           78      280
Spain          60           22           13       95
Germany        33           77           30      130

我可以添加什么来查询给我一个垂直总数ie -

        Product 1    Product 2    Product 3     Total    etc...
All Countries   ?            ?            ?        ?
France        103           99           78      280
Spain          60           22           13       95
Germany        33           77           30      130

我目前在收到查询后在PHP中执行此操作但是必须有一种方法可以在查询中执行此操作吗？
