--------- ------------- --------- ------------- -------------
10 00 00     10         00  00              Div1
10 10 00        10          10  00         Div1_Saf1

11 11 12        11          11  12         Div2_Saf2_Pos3

Types
Code        Name
--------        --------
C       Cards
P       Plates
S       Stickers

我想要一个选择的结果如下：

Main_Code    Division_Code Safe_Code Position_Code Main_Name    Cards Plates Stickers Total
----------------------------------------------------------------------------------------
10 00 00          10         00 00    Div1      1    1       2     4
10 10 00          10            10  00    Div1_Saf1 0    1      1      2
10 10 10          10            10  10    Div1_Saf1_Pos1    0    0      1      1
11 00 00          11            00  00    Div2      1    1      0      2
11 10 00          11            10  00    Div2_Saf1 0    1      0      1
11 10 10          11            10  10    Div2_Saf1_Pos1    0    1      0      1

任何人都可以尽快帮助我。

您正在寻找将行旋转为列，试试这个：

SELECT
  s.[Main_Code],
  s.Division_Code,
  s.Safe_Code,
  s.Position_Code,
  s.Main_Name,
  SUM(CASE WHEN t.Name ='Cards' THEN 1 ELSE 0 END) AS Cards, 
  SUM(CASE WHEN t.Name ='Plates' THEN 1 ELSE 0 END) AS Plates, 
  SUM(CASE WHEN t.Name ='Stickers' THEN 1 ELSE 0 END) AS Stickers,
  COUNT(t.Name) AS Total
FROM Storage s
INNER JOIN Article a ON a.Storage_code = s.[MainCode]
INNER JOIN Types   t ON a.Type_code = t.Code
GROUP BY s.Main_Code,
         s.Division_Code,
         s.Safe_Code,
         s.Position_Code,
         s.Main_Name;
