我的做法如下, 請參考

[Latitude] decimal(7,4),[ORDER] NVARCHAR(10),[FeederCode_NEW] NVARCHAR(20))

※ 引述《f127doggpig (阿賢)》之銘言：
: 各位好 目前我用DECLARE在＠TEMP增加欄位
: DECLARE @Temp TABLE ([FeederName] nvarchar(50) , [Longitude] decimal(7,4) ,
: [Latitude] decimal(7,4),[ORDER] NVARCHAR(10),[FeederCode_NEW] NVARCHAR(20))
: INSERT INTO @Temp ( [FeederName],[Longitude],[Latitude],[ORDER],[FeederCode_NEW] )select [FeederName],[Longitude],[Latitude] ,[ORDER],[FeederCode_NEW]
: from [Tlis].[dbo].[TaipowerAccount]
: 每一筆的資料
: [FeederName]可能是一樣[FeederCode_NEW]也會是一樣，但是藉由[Longitude],
: [Latitude],[ORDER]來區分
: 也就是
: [FeederName],[Longitude],[Latitude],[ORDER],[FeederCode_NEW]
: A , 120 , 50 , 1 , WS
: A , 121 , 12 , 5 , WS
: B , 120 , 50 , 3 , SD
: B , 52 , 12 , 4 , SD
: C , 120 , 50 , 1 , WE
: C , 52 , 12 , 3 , WE
: Z
: PIVOT 之後
: 變成以相同的[Longitude],[Latitude]列出重複的前6筆資料分別有他們的[FeederName],
: [ORDER],[FeederCode_NEW]
: 也就是
: 120,50,A,1 ,WS,B,3,SD,C,1,WE,NULL,NULL,NULL,NULL,NULL....... 補滿第6筆
: 121,12,A,12,WS,,NULL,NULL,NULL,NULL,........................ 補滿第6筆
: 我該如何pivot呢？ 謝謝
