修改結果表

Question

我使用SQL Server 2008的

這是結果表

ItemCode ItemName   Branch  Total Weight 
------------------------------------------------------ 
FBV0001 SML WATER ARWA  Bayan   144.00 
FDR0014 RED LENTIL   Al Balad  3000.00 
FDR0014 RED LENTIL   Solidere 13500.00 
FDR0017 EGYPTIAN RICE  Solidere 75500.00 

如何修改結果如下

ItemCode ItemName   Bayan  Al Balad Solidere 
-------------------------------------------------------------- 
FBV0001 SML WATER ARWA  144.00  0   0 
FDR0014 RED LENTIL   0  3000.00   0 
FDR0014 RED LENTIL   0   0  13500.00 
FDR0017 EGYPTIAN RICE   0   0  75500.00 

我已經試過很多查詢，但它不管用。請給出一個想法如何獲得這個。

Answer 1

使用Pivot表運算符。事情是這樣的：

WITH CTE 
AS 
(
    SELECT *, ROW_NUMBER() OVER(ORDER BY ItemCode) AS RN 
    FROM tablename 
) 
SELECT 
    ItemCode, 
    ItemName, 
    [Bayan], [Al Balad], [Solidere] 
fROM CTE AS t 
PIVOT 
(
    MAX(TotalWeight) 
    FOR Branch IN ([Bayan], [Al Balad], [Solidere]) 
) AS p; 

需要注意的是：我用ROW_NUMBER()產生通過它來使用一組唯一的ID。如果您沒有使用ROW_NUMBER()，你會從兩個只得到一個行：

FDR0014  RED LENTIL 
FDR0014  RED LENTIL 

看到它在這裏的行動：

• SQL Fiddle Demo。

這會給你：

| ITEMCODE |  ITEMNAME | BAYAN | AL BALAD | SOLIDERE | 
------------------------------------------------------------ 
| FBV0001 | SML WATER ARWA | 144 | (null) | (null) | 
| FDR0014 |  RED LENTIL | (null) |  3000 | (null) | 
| FDR0014 |  RED LENTIL | (null) | (null) | 13500 | 
| FDR0017 | EGYPTIAN RICE | (null) | (null) | 75500 | 

Answer 2

嘗試this..here SQL FIDDLE DEMO

Select [itemcode],[itemname], 
(Case when [branch]='Bayan' then [totalweight] else 0 end) as Bayan, 
(Case when [branch]='AL BALAD' then [totalweight] else 0 end) as AL_BALAD, 
(Case when [branch]='SOLIDERE' then [totalweight] else 0 end) as SOLIDERE 
from Tablename 

輸出是這樣的..

ItemCode   ItemName     Bayan  Al Balad   Solidere 
FBV0001  SML WATER ARWA    144   0    0 
FDR0014  RED LENTIL     0  3000    0 
FDR0014  RED LENTIL     0   0    13500 
FDR0017  EGYPTIAN RICE     0   0    75500
