有时，解决问题的第一步是知道它的名字。在那之后，这只是谷歌搜索的问题。您尝试创建的内容称为 或 。这是解释如何在MySQL中创建数据透视表的链接。这是更深入的教程。
现在，您已经更新了问题，对于您要完成的工作，我有了更清晰的认识。我将为您提供一个替代解决方案，该解决方案与基于MysqL的GROUP_CONCAT函数的相似但不 完全相同 。
select t1.FirstName, t1.LastName, group_concat(concat(t2.FirstName, ' ', t2.LastName))
from member_information as t1
left outer join member_dependent_information as t2 on t2.MemberID=t1.MemberID
group by t1.MemberID;
我已验证此查询，如下所示。首先设置：
create table member_information (
MemberID int unsigned auto_increment primary key,
FirstName varchar(32) not null,
LastName varchar(32) not null
) engine=innodb;
create table member_dependent_information (
MemberID int unsigned not null,
FirstName varchar(32) not null,
LastName varchar(32) not null,
Type int unsigned not null,
foreign key (MemberID) references member_information(MemberID)
) engine=innodb;
insert into member_information (MemberID, FirstName, LastName) values
(1, 'John', 'Harris'),
(2, 'Sarah', 'Thompson'),
(3, 'Zack', 'Lewis');
insert into member_dependent_information (MemberID, FirstName, LastName, `Type`) values
(1, 'Amy', 'Harris', 1),
(2, 'Bryan', 'Thompson', 1),
(2, 'Dewey', 'Thompson', 2),
(2, 'Tom', 'Thompson', 2),
(3, 'Harry', 'Lewis', 2),
(3, 'Minka', 'Lewis', 1);
现在查询和结果：
MysqL> select t1.FirstName, t1.LastName, group_concat(concat(t2.FirstName, ' ', t2.LastName))from member_information as t1
-> left outer join member_dependent_information as t2 on t2.MemberID=t1.MemberID
-> group by t1.MemberID;
+-----------+----------+------------------------------------------------------+
| FirstName | LastName | group_concat(concat(t2.FirstName, ' ', t2.LastName)) |
+-----------+----------+------------------------------------------------------+
| John | Harris | Amy Harris |
| Sarah | Thompson | Bryan Thompson,Dewey Thompson,Tom Thompson |
| Zack | Lewis | Harry Lewis,Minka Lewis |
