SQL Server：根据参数输入创建动态表答案

【问题标题】：SQL Server : create dynamic table based on parameter inputSQL Server：根据参数输入创建动态表
【发布时间】：2019-09-29 09:29:22
【问题描述】：

我想根据我的报表用户的输入参数创建一个动态表。选择ProfitCenterID 时，我希望此ProfitCenterID 显示为1 级，所有子ProfitCenterID 显示为2 级到xx 级。

当参数 /ProfitCenterID 设置为“业务单位 A”时，我需要一个包含此层次结构中所有 ProfitcenterID 的表。我在下面有一个示例，显示了所需的结果。

我的ProfitCenterID 的结构如下面的示例数据所示。我的实际生产数据有 19 个级别，用户可以从列ProfitCenterID 中选择一个输入值参数。

我的报告工具是 Tableau，我使用带有参数的自定义 SQL 查询连接到我的 MS SQL 服务器数据库。

时间：

ProfitcenterID_Level 为 4（与“业务单元 A”一样）WHERE 子句必须使用列 ProfitCenterID_Level_04

ProfitcenterID_Level 是 5（因为它是“帐户 1”），WHERE 子句必须使用列 ProfitCenterID_Level_05

ProfitcenterID_Level 是 6（因为它是“D-123400”），WHERE 子句必须使用列 ProfitCenterID_Level_06

我不知道如何根据ProfitcenterID 中的值创建此查找，它为我提供ProfitcenterID_Level。

下面的示例数据和期望的结果示例。

样本数据：

CREATE TABLE [Sample]
(
    ProfitCenterID nchar(30)
    ,ProfitCenterID_Level smallint
    ,ProfitCenterID_Level_01 nchar(30)
    ,ProfitCenterID_Level_02 nchar(30)
    ,ProfitCenterID_Level_03 nchar(30)
    ,ProfitCenterID_Level_04 nchar(30)
    ,ProfitCenterID_Level_05 nchar(30)
    ,ProfitCenterID_Level_06 nchar(30)
    ,ProfitCenterID_Level_07 nchar(30)
)

INSERT INTO [Sample]
VALUES ('Business Unit A','4','Global Enterprise','Europe','Denmark','Business Unit A','','',''),
('Account 1','5','Global Enterprise','Europe','Denmark','Business Unit A','Account 1  ','',''),
('D-123400','6','Global Enterprise','Europe','Denmark','Business Unit A','Account 1  ','D-123400',''),

('D-123499','7','Global Enterprise','Europe','Denmark','Business Unit A','Account 1  ','D-123490','D-123499')

所需结果（在选择“业务单位时” - 级别4 ）：

    SELECT [ProfitCenterID]
          ,[ProfitCenterID_Level]
          -- ,[ProfitCenterID_Level_01]

      FROM [MyDatabase].[dbo].[Sample]
      WHERE ProfitCenterID_Level_04 = 'Business Unit A' 
 /****** 'Business Unit A' is the input parameter from my report user  ******/

所需结果（在选择“帐户1”时 - 级别5 ）：

【问题讨论】：

你能发布一些示例数据吗？
请不要张贴图片来显示您的样本和预期结果；他们无法帮助您寻求帮助的用户，因为我们无法利用他们。花点时间发布 DDL 和 DML 语句，并格式化 text 以获得您的预期结果。不要忘记包括您的尝试。
大家好。感谢您的投入。我在下面的答案中包含了我的示例数据。
好的，所以您的要求是获得一个动态表，其中当您选择业务单位时，应显示业务单位列，否则如果您选择帐户，则应跳过业务单位列和行，仅应显示帐户显示对了吗？
在图像中你也显示到 4 级和 3 级，所以不需要其他级别？

我能够使用示例重新创建报告，并且能够实现所需的功能。

如果需要，我可以共享工作簿
