想要关于 sqlcode 的另一种简码

Question

拜托，我想换个方式

示例数据

date	tomato	phone	book	pen
2022-05-15	2	2	3	1
2022-05-15	3	3	3	2

我看到了这个结果

date	tomato	phone	book	pen
2022-05-15	5	5	6	3

我用这个

insert into sales.copy 
select date, 
       sum(tomato), 
       sum(phone), 
       sum(book), 
       sum(pen) 
from copy 
where date = '2022-05-15';

delete from sales.copy 
where date = '2022-05-15' 
LIMIT 2;

但我想用另一种方式缩短这部分

'date, sum(tomato), sum(phone)...'

Answer 1

所以只需对结果进行分组

select date, 
       sum(tomato), 
       sum(phone),
       sum(book), 
       sum(pen) 
from copy 
where date = '2022-05-15' 
GROUP BY date
