如何构建使用动态SQL返回以下列的数据集。
联名，联名地址，CFO 1名称，CFO 1电子邮件，CFO 1电话，CFO 2名称，CFO 2电子邮件，CFO 2电话，...主任1名称，主任1电子邮件，主任1电话...到5，总裁1的姓名，等等。排成一排。
我的数据库中有四个表：
联系方式：
X18_Digit_Contact_ID__c | Name | Email | Phone | Federation_ID
------------------------------------------------------------------------------------------
1 | John Smith | x9@gmail.com | 546-5464889 | 1
2 | David smith | x8@gmail.com | 145-5464889 | 1
3 | Ellen Smith | x9@gmail.com | 546-5464889 | 1
4 | Dan smith | x8@gmail.com | 145-5464889 | 1
5 | Kelly Smith | x9@gmail.com | 546-5464889 | 2
6 | Dori smith | x8@gmail.com | 145-5464889 | 2
7 | Nir Smith | x9@gmail.com | 546-5464889 | 2
8 | Victor smith | x8@gmail.com | 145-5464889 | 2
隶属关系：
X18_Digit_Contact_ID__c | npe5__Role__c
-----------------------------------------------
4 | President
8 | President
联盟：
Federation_ID | Name | Address
---------------------------------------
1 | x | 123 hello
2 | y | 345 world
选区：
X18_Digit_Contact_ID__c | Constituency
-----------------------------------------------
1 | CFO
2 | CFO
3 | Director
7 | Director
5 | Director
6 | Director
联盟1的预期结果：
Name | Address | CFO 1 | CFO 1 Email | CFO 1 Phone | CFO 2 | CFO 2 Email | CFO 2 Phone | Director 1 | Director 1 Email | Director 1 Phone | President 1 | President 1 Email | President 1 Phone|
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
x | 123 hello | John Smith | x9@gmail.com | 546-5464889 | David smith | x8@gmail.com | 145-5464889 | Ellen Smith | x9@gmail.com | 546-5464889 | Dan smith | x8@gmail.com | 145-5464889
每个联盟可以有多个具有相同选区和隶属关系的联系人。
例如，联盟“ x”可以有一个以上的CFO和一个以上的主管。这些信息来自选区表。 （这些数字是动态的。）
然后，同一个联盟最多可以有一位主席，而该信息来自关联表。
这是我的开始方式，但并没有完全按照我的期望进行。

--return

EXECUTE (@query)
此代码仅返回一名CFO和一名董事，而没有总裁。

这个评论太长了。当我们寻找消耗性数据时，帮助您使用它的人应该很容易。这是应该发布此信息的方式，以便其他人可以对其进行查询。

今天我没有更多时间为您提供帮助。也许其他人也可以使用我创建的数据来提供帮助。

谢谢你们的帮助。
整整一天后，我想出了一些对我有用的东西。这可能不是解决此问题的最佳方法，但它确实有效。
希望这可以帮助其他人。
