SQL合并统一数据（相同的在一行显示）

/*问题描述
表Library有字段         表EmployeeInfo  字段
LibraryId                         EmpId
EmpId
LibraryTitle
LibraryOwner                      Name

测试表Library数据为
insert into Library(EmpId,LibraryTitle,Name) values('001','规章制度','001')
insert into Library(EmpId,LibraryTitle,Name) values('001','公共信息','001,002,003')
测试表EmployeeInfo  数据为
insert into EmployeeInfo  (EmpId,Name) values('001','小王')
insert into EmployeeInfo  (EmpId,Name) values('002','小陈)
insert into EmployeeInfo  (EmpId,Name) values('003','小张')

有什么办法能在前台显示的时候显示为
EmpId  LibraryTitle   Name 
001    规章制度       小王
001    公共信息       小王,小陈，小张
