Question

我使用的是SQL Server，我需要按列显示查询信息。目前，信息显示为：

ProjectID   FiscYr  Period  Amt 
4231        2015    1       100 
4231        2015    1       820 
***         ***    ***      *** 
***         ***    ***      ***
4231        2015    12      733

需要格式化为：

ProjectID   FiscYr  Period 01   Period 02   *** ***  Period 12
4231        2015         100         820    *** ***  733

现有查询是：

SELECT        substring([project],11,4) as ProjectID
               ,substring([fiscalno],1,4) as FiscYr
               ,substring([fiscalno],5,2) as Period
               ,sum([amount]) as Amt
FROM [dbo].[PJTran] 
WHERE (((pjtran.gl_Acct) Like '12%' or (pjtran.gl_Acct) Like '13%')) 
group by substring([project],11,4),substring(fiscalno,1,4),substring([fiscalno],5,2);

Answer 1

将查询包装在公用表表达式中，然后应用pivot运算符：

WITH CTE AS (
    SELECT        
         SUBSTRING([project],11,4) AS ProjectID
       , SUBSTRING([fiscalno],1,4) AS FiscYr
       ,'Period ' + SUBSTRING([fiscalno],5,2) AS Period
       , Amount
    FROM [dbo].[PJTran] 
    WHERE pjtran.gl_Acct LIKE '1[23]%' 
)

SELECT * FROM CTE
PIVOT (SUM(Amount) FOR Period IN (
    [Period 1],[Period 2], [Period 3], [Period 4],
    [Period 5],[Period 6], [Period 7], [Period 8],
    [Period 9],[Period 10],[Period 11],[Period 12]
    )
) p;

将列显示为行
