SQL Server：遞歸CTE？從組織結構創建報告

我希望有人能幫助我。我想要一份報告，其中包含計算組織結構的報告。SQL Server：遞歸CTE？從組織結構創建報告

CREATE TABLE Organistation 
    (

INSERT INTO dbo.Organistation

VALUES (1, 1, '1_SubCompany'), 
      (2, 1, '2_SubCompany'), 
      (3, 1, '3_SubCompany'), 
      (4, 1, '4_SubCompany'), 
      (5, 1, '5_SubCompany'), 
      (6, 1, '6_SubCompany'), 
      (7, 1, '7_SubCompany') 

CREATE TABLE EMPLOYEES 
    (
    EMPLOYID NUMERIC(12, 0) , 
    KeySubCompany NUMERIC(12, 0) , 
    NAME VARCHAR(255) 
) 


INSERT INTO dbo.EMPLOYEES 
      (EMPLOYID, KeySubCompany, NAME) 
VALUES (1, 1, 'Winny'),

      (1, 4, 'Leon'), 
      (1, 4, 'Marcy'), 
      (1, 7, 'Peter')

我期望的結果是：

在表Company我希望能夠配置組織結構的深度在我的報告（目前視圖深度3）

我目前的解決方案：

.....等等，直到O12

正如你所看到的，它幾乎只是複製/粘貼組織結構有點不同。

有沒有一種方法來創建一個「乾淨」的版本來創建一個這樣的報告？

我創建具有相同的結構，我的數據庫/表我目前所面對的一個「簡單」，所以它不可能改變表結構。

在此先感謝。

之前，我忘了SQL Fiddle Demo

是的。使用CTE。閱讀http://technet.microsoft.com/en-us/library/ms190766(v=sql.105).aspx和http://msdn.microsoft.com/en-gb/library/ms175972.aspx – podiluska

ok thx我會檢查出來 – WhoisIt

嗯對不起IAM這種新的..這個檢查出來，但我怎麼能創建一個這樣的CTE報告？ – WhoisIt

看看下面的東西。這是我知道的創建分層列表的最簡單的方法。如果您無法更改基礎表結構，則在#temp表中準備數據，然後再製作10層嵌套CTE會更容易。

SQLFiddle

CREATE TABLE Grp_lvl_1 (
    Id INT IDENTITY(1,1) NOT NULL, 
    Name NVARCHAR(50)) 

CREATE TABLE Grp_lvl_2 (
    Id INT IDENTITY(1,1) NOT NULL, 
    lvl_1_Id INT, 
    Name NVARCHAR(50)) 

INSERT Grp_lvl_1 (Name) VALUES 
('Continent_1'), 
('Continent_2'), 
('Continent_3') 

INSERT Grp_lvl_2 (lvl_1_Id, Name) VALUES 
(1,'Country_1'), 
(1,'Country_2'), 
(1,'Country_3'), 
(2,'Country_4'), 
(2,'Country_5'), 
(2,'Country_6'), 
(3,'Country_7'), 
(3,'Country_8'), 
(3,'Country_9') 

SELECT Grp_lvl_1.Name col1, Grp_lvl_2.Name col2 
FROM Grp_lvl_1 INNER JOIN 
Grp_lvl_2 ON Grp_lvl_1.Id = Grp_lvl_2.lvl_1_Id

沒有，有沒有必要遞歸CTE，一個ROLLUP能得到您的報告

如果使用SQLServer的2008年或在HAVING更好的條件列表可取代通過使用GROUPING_ID的單個條件，它返回ROLLUP,CUBE和GROUPING SETS中的分組級別，作爲位圖的int值，因此該值需要轉換，位圖處於相同的orde所以你希望看到更高的細節越少，將使用GROUPING_ID的值作爲下限。

SELECT c.KeyCompany 
    , COUNT(e.EMPLOYID) CountEmployees 
    , o.o1, o.o2, o.o3, o.o4, o.o5, o.o6 
    , o.o7, o.o8, o.o9, o.o10, o.o11, o.o12 
FROM Organistation o 
     INNER JOIN SUBCOMPANY s ON o.KeySubCompany = s.KeySubCompany 
     INNER JOIN COMPANY c ON s.KeyCompany = c.KeyCompany 
     INNER JOIN EMPLOYEES e ON o.KeySubCompany = e.KeySubCompany 
GROUP BY c.KeyCompany, RollUp(o.o1, o.o2, o.o3, o.o4, o.o5, o.o6 
          , o.o7, o.o8, o.o9, o.o10, o.o11, o.o12) 
HAVING GROUPING(o.o1) = 0 
    AND GROUPING_ID(o.o1, o.o2, o.o3, o.o4, o.o5, o.o6 
       , o.o7, o.o8, o.o9, o.o10, o.o11, o.o12) 
    > power(2, 11 - (MAX(c.viewdepth) + 1)) 
ORDER BY COUNT(e.EMPLOYID)

SQLFiddle演示

如果您使用SQLServer的2005年或更早versione查詢會更詳細

SELECT c.KeyCompany 
    , COUNT(e.EMPLOYID) CountEmployees 
    , o.o1, o.o2, o.o3, o.o4, o.o5, o.o6 
    , o.o7, o.o8, o.o9, o.o10, o.o11, o.o12 
FROM Organistation o 
     INNER JOIN SUBCOMPANY s ON o.KeySubCompany = s.KeySubCompany 
     INNER JOIN COMPANY c ON s.KeyCompany = c.KeyCompany 
     INNER JOIN EMPLOYEES e ON o.KeySubCompany = e.KeySubCompany 
GROUP BY c.KeyCompany, RollUp(o.o1, o.o2, o.o3, o.o4, o.o5, o.o6 
          , o.o7, o.o8, o.o9, o.o10, o.o11, o.o12) 
HAVING GROUPING(o.o1) = 0 
    AND (GROUPING(o.o1) = 1 OR (GROUPING(o.o1) = 0 AND MAX(c.viewdepth) + 1 >= 1)) 
    AND (GROUPING(o.o2) = 1 OR (GROUPING(o.o2) = 0 AND MAX(c.viewdepth) + 1 >= 2)) 
    AND (GROUPING(o.o3) = 1 OR (GROUPING(o.o3) = 0 AND MAX(c.viewdepth) + 1 >= 3)) 
    AND (GROUPING(o.o4) = 1 OR (GROUPING(o.o4) = 0 AND MAX(c.viewdepth) + 1 >= 4)) 
    AND (GROUPING(o.o5) = 1 OR (GROUPING(o.o5) = 0 AND MAX(c.viewdepth) + 1 >= 5)) 
    AND (GROUPING(o.o6) = 1 OR (GROUPING(o.o6) = 0 AND MAX(c.viewdepth) + 1 >= 6)) 
    AND (GROUPING(o.o7) = 1 OR (GROUPING(o.o7) = 0 AND MAX(c.viewdepth) + 1 >= 7)) 
    AND (GROUPING(o.o8) = 1 OR (GROUPING(o.o8) = 0 AND MAX(c.viewdepth) + 1 >= 8)) 
    AND (GROUPING(o.o9) = 1 OR (GROUPING(o.o9) = 0 AND MAX(c.viewdepth) + 1 >= 9)) 
    AND (GROUPING(o.o10) = 1 OR (Grouping(o.o10) = 0 
          AND MAX(c.viewdepth) + 1 >= 10)) 
    AND (GROUPING(o.o11) = 1 OR (GROUPING(o.o11) = 0 
          AND MAX(c.viewdepth) + 1 >= 11)) 
    AND (GROUPING(o.o12) = 1 OR (GROUPING(o.o12) = 0 
          AND MAX(c.viewdepth) + 1 >= 12)) 
ORDER BY COUNT(e.EMPLOYID)

的訣竅是在HAVING，線條

(GROUPING(o.o4) = 1 OR (GROUPING(o.o4) = 0 AND MAX(c.viewdepth) + 1 >= 4))

刪除返回的所有行3210未分組（Grouping(o.o4) = 1）或深度低於最大需求（GROUPING(o.o4) = 0 AND MAX(c.viewdepth) + 1 >= 4)）。
