如何在SQLite中从分组列连接/连接字符串？

Question

有

Company
id      Name
1       Enron
2       Walmart

Employee
id      Company
2       1
3       1
4       2
5       2
6       2

我想得到

Enron 2,3
Walmart 4,5,6

到目前为止我写道:

select Company.Name, Employee.id
from Company inner join Employee
on Company.id = Employee.Company 
group by Company.id

但目前的结果是

Enron 2
Walmart 4

Answer 1

使用Group_Concat:

select Company.Name, Group_Concat(Employee.id)
from Company inner join Employee
on Company.id = Employee.Company 
group by Company.id
