Sql 从3个表中选择数据，而多个值应以逗号分隔

我有以下三个表格：

。。。。。。。 .......

我运行以下查询

SELECT Employee.EmployeeId,
  EmployeeName,
  ProjectName
FROM Employee
JOIN ProjEmp
ON Employee.EmployeeId=ProjEmp.EmployeeId
JOIN Project
ON Project.ProjectId=ProjEmp.ProjectId

并给出如下结果：

但我需要这样的结果：

请为我提供所需结果的最佳查询。

您可以执行以下操作以获得所需结果：

WITH CTE AS(SELECT Employee.EmployeeId,
  EmployeeName,
  ProjectName
FROM Employee
JOIN ProjEmp
ON Employee.EmployeeId=ProjEmp.EmployeeId
JOIN Project
ON Project.ProjectId=ProjEmp.ProjectId)

SELECT EmployeeId,EmployeeName,
      ProjectName = STUFF((
          SELECT ',' + convert(varchar(10),T2.ProjectName)
          FROM CTE T2
          WHERE T1.EmployeeName = T2.EmployeeName
          FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
FROM CTE T1
GROUP BY EmployeeId,EmployeeName
ORDER BY EmployeeId

结果:

EMPLOYEEID   EMPLOYEENAME   PROJECTNAME
1            Emp1           ProjA,ProjB
3            Emp3           ProjC
4            Emp4           ProjC,ProjD
5            Emp5           ProjE
7            Emp7           ProjE
8            Emp8           ProjE
