Answer 1

您必须为“最后一周”提供一些空值

  SELECT [Order], Dept, Area,'' as [Final Week], Total
     FROM dbo.DeptSummary10Weeks

只需尝试以下方法...

Declare @var nvarchar(max)
Select @var = coalesce(@var +',','') + cast(WeekNum as nvarchar(20)) from dbo.[10Weeks]    
FOR [Final Week] IN ('+@var+') AS PivotTable;

Answer 2

尝试使用显式WeekNum并在查询中添加右括号：

SELECT *
FROM (
  SELECT [Order], Dept, Area, [Final Week], Total
 FROM dbo.DeptSummary10Weeks
) AS SourceTable 
PIVOT (Sum(Total) FOR [Final Week] IN ([1], [2], [3], [4], [5], [6], [7])) AS PivotTable

更新：

尝试使用动态数据透视表：

declare @cols nvarchar(max);
declare @sql  nvarchar(max);
  select @cols = stuff((
    select distinct 
      ' , ' + CONCAT('[', CONVERT(varchar(10),  t.WeekNum), ']')
      from dbo.[10Weeks] t 
      order by 1
      for xml path (''), type).value('.','nvarchar(max)')
    ,1,2,'')

select  @sql = '
    SELECT *
    FROM (
         SELECT [Order], Dept, Area, [Final Week], Total
         FROM dbo.DeptSummary10Weeks
    ) AS SourceTable 
    PIVOT (Sum(Total) FOR [Final Week] IN (' + @cols + ') ) AS PivotTable'   

exec(@sql);

SQL中的PIVOT查询
