刪除不需要的列透視

Question

我的表是這樣的：

CEID BUID WEIGHT TREND SCORE Quarter 
--------------------------------------- 
CE001 BU001 4  5  20  1 
CE001 BU001 4  0  22  2 
CE001 BU001 4  0  23  3 
CE001 BU001 4  0  24  4 

我想要的結果是這樣的

CEID BUID WEIGHT TREND Q1 Q2 Q3 Q4 
--------------------------------------- 
CE001 BU001 4  NA 20 22 23 24 

我寫了下面的透視查詢：

select * 
from table 
pivot (sum (score) for quarter in ([1],[2],[3],[4])) as ScorePerQuarter 

但是，既然趨勢也在變化，我得到了Pivoted查詢中的多個行，以及不同的趨勢值..

我怎樣才能達到上述結果？即：從查詢中刪除趨勢列。

Answer 1

只要停止使用SELECT *對主表，並留下了TREND柱：

;WITH t AS 
(
    select CEID, BUID, WEIGHT, SCORE, Quarter from dbo.table 
) 
SELECT * FROM t 
pivot (sum (score) for quarter in ([1],[2],[3],[4])) as ScorePerQuarter; 

如果你想TREND = NA如在「結果我想要的」，只是硬編碼：

;WITH t AS 
(
    select CEID, BUID, WEIGHT, TREND = 'NA', SCORE, Quarter from dbo.table 
) 
SELECT * FROM t 
pivot (sum (score) for quarter in ([1],[2],[3],[4])) as ScorePerQuarter;
