SSRS DataSet 不同字段依赖于参数答案

【问题描述】：

我正在使用存储过程为我的 SSRS 报告提供数据集。在我的存储过程中有一个名为@ReportType 的参数。我使用它是因为我有两个报告使用相同的数据子集，但是它们根据 @ReportType 返回不同的列，并且在一个报告类型中我汇总了数据。

所以例如我的存储过程的结尾如下：

---Income
IF @Rpt_Type = 'Income'
    BEGIN

        SELECT  
                EXPENSE_TYPE    
            ,   ACCOUNT_NAME            
            ,   CURRENCY                
            ,   SETTLEMENT_DATE         
            ,   ISSUE           
            ,   ISSUE_DESCRIPTION       
            ,   SETTLEMENT_AMOUNT       
            ,   TRANSACTION_STATUS      
            ,   TRANSACTION_CATEGORY    
            ,   TRANSACTION_SUBCATEGORY
            ,   TRANSACTION_DESCRIPTION
        FROM #RESULT_SET 
        WHERE TRANSACTION_CATEGORY IN ('IN','IF') OR (TRANSACTION_CATEGORY IN ('CD','CW') AND TRANSACTION_SUBCATEGORY IN ('INT','SLI','RDS','INS','INC'))
        ORDER BY expense_type,settlement_date,issue_description
    END

---Expenses
IF @Rpt_Type = 'Expenses'
    BEGIN
        BEGIN
        SELECT 
                ACCOUNT_NAME            AS [Portfolio_Number]
            ,   TRANSACTION_SUBCATEGORY AS [Cash_flow_type]
            ,   TRANSACTION_DESCRIPTION AS [Cash_Flow_Description]
            ,   COUNT(ACCOUNT_NAME)     AS [Number Of Transactions]
            ,   @ReportEndDate          AS [EndDate]
        FROM #RESULT_SET 
        WHERE TRANSACTION_SUBCATEGORY IN ('CCD','CCW','FSB','FSS','FFB','FFS','FSO','FSC','FFO','FFC')
          AND INQ_BASIS_NUM = '1'
        GROUP BY ACCOUNT_NAME,TRANSACTION_SUBCATEGORY,TRANSACTION_DESCRIPTION,TRANSACTION_CATEGORY
        ORDER BY ACCOUNT_NAME,TRANSACTION_SUBCATEGORY,TRANSACTION_DESCRIPTION,TRANSACTION_CATEGORY
    END

我的问题是如何让 SSRS 返回每种报告类型的不同列？在将列返回到 SSRS 供我使用之前，有没有一种方法可以创建可以提供参数的数据集？我是否必须在 SSRS 中创建两个数据集来满足所需的不同列？

【解决方案1】：

只要您为每个@Rpt_Type 返回相同的列名，这将起作用。对于 @Rpt_Type 'Income'，为 @Rpt_Type 'Expenses' 数据返回 NULL 值，反之亦然。否则，报表将期望它不是从数据集中获取的列，并且数据集将失败：

---Income
IF @Rpt_Type = 'Income'
    BEGIN

        SELECT  
                EXPENSE_TYPE    
            ,   ACCOUNT_NAME            
            ,   CURRENCY                
            ,   SETTLEMENT_DATE         
            ,   ISSUE           
            ,   ISSUE_DESCRIPTION       
            ,   SETTLEMENT_AMOUNT       
            ,   TRANSACTION_STATUS      
            ,   TRANSACTION_CATEGORY    
            ,   TRANSACTION_SUBCATEGORY
            ,   TRANSACTION_DESCRIPTION
            ,   NULL Portfolio_Number
            ,   NULL Cash_flow_type
            ,   NULL Cash_Flow_Description
            ,   NULL [Number Of Transactions]
            ,   NULL EndDate
        FROM #RESULT_SET 
        WHERE TRANSACTION_CATEGORY IN ('IN','IF') OR (TRANSACTION_CATEGORY IN ('CD','CW') AND TRANSACTION_SUBCATEGORY IN ('INT','SLI','RDS','INS','INC'))
        ORDER BY expense_type,settlement_date,issue_description
    END

---Expenses
IF @Rpt_Type = 'Expenses'
    BEGIN
        BEGIN
        SELECT  NULL EXPENSE_TYPE    
            ,   NULL ACCOUNT_NAME            
            ,   NULL CURRENCY                
            ,   NULL SETTLEMENT_DATE         
            ,   NULL ISSUE           
            ,   NULL ISSUE_DESCRIPTION       
            ,   NULL SETTLEMENT_AMOUNT       
            ,   NULL TRANSACTION_STATUS      
            ,   NULL TRANSACTION_CATEGORY    
            ,   NULL TRANSACTION_SUBCATEGORY
            ,   NULL TRANSACTION_DESCRIPTION
            ,   ACCOUNT_NAME            AS [Portfolio_Number]
            ,   TRANSACTION_SUBCATEGORY AS [Cash_flow_type]
            ,   TRANSACTION_DESCRIPTION AS [Cash_Flow_Description]
            ,   COUNT(ACCOUNT_NAME)     AS [Number Of Transactions]
            ,   @ReportEndDate          AS [EndDate]
        FROM #RESULT_SET 
        WHERE TRANSACTION_SUBCATEGORY IN ('CCD','CCW','FSB','FSS','FFB','FFS','FSO','FSC','FFO','FFC')
          AND INQ_BASIS_NUM = '1'
        GROUP BY ACCOUNT_NAME,TRANSACTION_SUBCATEGORY,TRANSACTION_DESCRIPTION,TRANSACTION_CATEGORY
        ORDER BY ACCOUNT_NAME,TRANSACTION_SUBCATEGORY,TRANSACTION_DESCRIPTION,TRANSACTION_CATEGORY
    END
