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
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
