Sql server 2008 存储过程（SQL SERVER 2008中的动态列）

我有三个表

项目

部门

和

项目状态

系

计划

项目状态

我想要下面的组合：

我试过这个

SELECT 
    Status=[Name],
    Software=(
        SELECT COUNT(*)
        FROM Projects 
        WHERE StatusID=PS.ID and DeptI =1
    ),
    XML1=( 
        SELECT COUNT(*)
        FROM Projects
        WHERE CurrentStatusID=PS.ID and DeptID=2
    ),
    Imaging=(
        SELECT COUNT(*)
        FROM Projects
        WHERE CurrentStatusID=PS.ID and DeptID =3
    )  
FROM
    [MIS_STORE].[dbo].[M_ProjectStatuses] PS   

在这里，我希望根据部门的数量动态检索列的数量。 先谢谢你

DECLARE @cols NVARCHAR(2000);
DECLARE @query NVARCHAR(4000);

                         '[' + Name + ']')

SET @query = 'SELECT [Status], '+
@cols +'
