如何为SSRS报告设置项目列表输出的存储过程

Question

我有一个查询，实质上是通过一个表列表（其列表从表中的字段中提取并存储在游标中）来比较无效数据，并且应该只返回列表有无效数据的表格。

我主要挣扎的是，我无法弄清楚如何正确设置存储过程以SSRS可以使用的方式输出列表。我在SSRS中需要的只是表格列表。

当我运行SP时，所有的查询都是＆＃39;结果显示在SSMS结果网格中 - 正如预期的那样，并且在“消息”选项卡中，我确实获得了包含无效数据的表的正确列表。

在我的研究中，为了弄清楚如何做到这一点，我只能找到返回单个值的示例。正如我所说，我需要返回一个值列表。

这是我的存储过程（注释代码是尝试将表列表存储到临时表中以便SSRS从中获取列表）：

USE MasterFiles
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

IF OBJECT_ID('sp_GetInvalidXrefCategories') IS NOT NULL
    DROP PROCEDURE sp_GetInvalidXrefCategories

CREATE PROCEDURE dbo.sp_GetInvalidXrefCategories

@includeClin bit,
@includePayroll bit,
