Bagaimana cara membuat kolom tambahan pada pivot tabel sql di SQL Server 2005?

Anda perlu menggabungkan label sebelum PIVOT. Daftar kolom juga perlu memperhitungkan kemungkinan penggabungan silang label:

SET NOCOUNT ON ; 

DECLARE @pivot_cols AS varchar(max) ; 
DECLARE @src AS TABLE 
    ( 
     ID int NOT NULL 
    ,Label varchar(14) NOT NULL 
    ,Numerator int NOT NULL 
    ,Denominator int NOT NULL 
    ,Ratio decimal(5, 4) NOT NULL 
    ) ; 

DECLARE @label_order AS TABLE 
    ( 
     Label varchar(14) NOT NULL 
    ,Sort int NOT NULL 
    ) 

DECLARE @sub_label_order AS TABLE 
    ( 
     SubLabel varchar(14) NOT NULL 
    ,Sort int NOT NULL 
    ) 

INSERT  INTO @src 
VALUES  (1, 'LabelNameOne', 41, 10, 4.1) ; 
INSERT  INTO @src 
VALUES  (1, 'LabelNameTwo', 0, 0, 0) ;

INSERT  INTO @sub_label_order

INSERT  INTO @sub_label_order
