ピボットSQL Serverで定義されている、重複のないフィールドのエイリアス

Question

ピボット列の名前を変更する方法を理解しようとしています。 IE201601〜1月、201602〜2月など

残りのコードは問題ありません。

私はselect文にエイリアスを追加すると、それは

など、月名で別の列を作成しますが、列の1月、2月に続くので、私は201601、201602などで終わる元を離れ、月

SELECT *, 

[201601] as January, 
[201602] as February, 
[201603] as March, 
[201604] as April, 
[201605] as May, 
[201606] as June, 
[201607] as July,  
[201608] as August,  
[201609] as September,  
[201610] as October,  
[201611] as November, 
[201612] as December 


FROM (
SELECT c.BLDGID AS 'BLDGID', 
     c.LEASID AS 'LEASID', 
     l.OCCPNAME AS 'OCCPNAME', 
     l.SUITID AS 'SUITID', 
     c.INCCAT AS 'INCCAT', 
     c.SRCCODE AS 'SRCCODE',

    ON l.BLDGID = c.BLDGID AND l.LEASID = c.LEASID 
WHERE c.BLDGID ='85000' 
    AND c.INCCAT ='RNT' 
    AND c.SRCCODE NOT LIKE 'CR' 
    AND c.SRCCODE NOT LIKE 'PR' 
    AND DESCRPTN NOT LIKE 'SECURITY APPLIED' 


    AND c.PERIOD > '201512'

最初の行にSELECT *を使用しているため、両方の列が表示されています。これを代わりに使用してください：

SELECT BLDGID, LEASID, OCCPNAME, SUITID, INCCAT, SRCCODE, 
    [201601] as January, 
    [201602] as February, 
    [201603] as March, 
    [201604] as April, 
    [201605] as May, 
    [201606] as June, 
    [201607] as July,  
    [201608] as August,  
    [201609] as September,  
    [201610] as October,  
    [201611] as November, 
    [201612] as December 

もちろん、来年はどうなりますか？クエリを更新し続ける必要があります。これで、あなたはそれを避けることができます。

SELECT * 
FROM (
SELECT c.BLDGID AS 'BLDGID', 
     c.LEASID AS 'LEASID', 
     l.OCCPNAME AS 'OCCPNAME', 
     l.SUITID AS 'SUITID', 
     c.INCCAT AS 'INCCAT', 
     c.SRCCODE AS 'SRCCODE', 
     c.TRANAMT AS 'TRANAMT', 
     DATENAME(MONTH, DATEADD(MONTH, CAST(SUBSTRING(c.PERIOD, 5, 2) AS INT), -1)) AS 'MONTH' 
FROM SQLDATA.dbo.LEAS l 
INNER JOIN SQLDATA.dbo.CMLEDG c 
    ON l.BLDGID = c.BLDGID AND l.LEASID = c.LEASID 
WHERE c.BLDGID &SPARM01 
    AND c.INCCAT &SPARM02 
    AND c.SRCCODE NOT LIKE 'CR' 
    AND c.SRCCODE NOT LIKE 'PR' 
    AND DESCRPTN NOT LIKE 'SECURITY APPLIED' 
    AND c.PERIOD > '201512' 
) as t 
PIVOT (
SUM(TRANAMT) 
FOR MONTH IN ('January','February','March','April','May','June','July','August','September','October','November','December')

最初の変更は、あなたの期間は、月の名前に変換され、そして、私はサブクエリであることを行う（201606 - たとえば用>「6月」、）、そうピボットテーブルはyyyymm形式が存在することさえ知りません。ピボットテーブルに使用されているリストで必要な月を使用するだけです。
