試試這個：

Select 
    id, 
    name, 
    group_concat(salary SEPARATOR '/') as salaries 
from tableName 
group by id

Answer 3

Group_Concat

嘗試這樣

Select id,name, group_concat(salary SEPARATOR '/') as salaries 
From table1 
Group by id 

Answer 4

您可以使用GROUP_CONCAT(expr)

SELECT 
    id, 
    `name`, 
    GROUP_CONCAT(salary SEPARATOR '/') AS salary 
FROM 
    `table` 
GROUP BY id
