SQL Server：递归CTE？从组织结构创建报告

我希望有人能帮助我。我想要一份报告，其中包含计算组织结构的报告。SQL Server：递归CTE？从组织结构创建报告

CREATE TABLE Organistation 
    (
    KeySubCompany NUMERIC(12, 0) ,

INSERT INTO dbo.Organistation

      (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) ,

) 


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

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

我期望的结果是：

在表Company我希望能够配置组织结构的深度在我的报告（目前视图深度3）

我目前的解决方案：

     CR.O2, 
     CR.O3.... UNION.... UNTIL O12

.....等等，直到O12

正如你所看到的，它几乎只是复制/粘贴组织结构有点不同。

有没有一种方法来创建一个“干净”的版本来创建一个这样的报告？

我创建具有相同的结构，我的数据库/表我目前所面对的一个“简单”，所以它不可能改变表结构。

在此先感谢。

之前，我忘了SQL Fiddle Demo

是的。使用CTE。阅读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我会检查出来 – WhoisIt

嗯对不起IAM这种新的..这个检查出来，但我怎么能创建一个这样的CTE报告？ – WhoisIt

看看下面的东西。这是我知道的创建分层列表的最简单的方法。如果您无法更改基础表结构，则在#temp表中准备数据，然后再制作10层嵌套CTE会更容易。

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

没有，有没有必要递归CTE，一个ROLLUP能得到您的报告

如果使用SQLServer的2008年或在HAVING更好的条件列表可取代通过使用GROUPING_ID的单个条件，它返回ROLLUP,CUBE和GROUPING SETS中的分组级别，作为位图的int值，因此该值需要转换，位图处于相同的orde所以你希望看到更高的细节越少，将使用GROUPING_ID的值作为下限。

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查询会更详细

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)

的诀窍是在HAVING，线条

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

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