SSRS报告中的数据为空

Question

我正在研究ssrs报告。我能够查看存储过程的数据或结果。不幸的是，当与报告的数据集相同时，我却看不到数据，而是获得了0条记录。这可能是什么原因？我的报告结构会如下图所示：

我当前的结果：

下面是我的程序：

我的程序结果如下图所示：

Answer 1

由于有些事情可能是错误的，因此我将执行以下操作。

1. 创建报告副本
2. 如果需要，删除现有的数据集和tablix。
3. 创建一些仅获取基本数据的新数据集（例如SELECT top 10 * FROM marks_emtry_HTS）。暂时不要使用您的参数，因为我们只想测试就可以获取基本数据。
4. 在报表中添加一些表以显示数据已返回
5. 通过使用select * from SplitStringByChar(@SectionId,',')之类的数据集查询来添加数据集以测试您是否正确传递和解析了参数，然后将tablix放在报表中以显示结果。
6. 尝试调整参数值SET @SectionId = LTRIM(RTRIM(@SectionId))，以确保您在分割函数中没有错误地处理前导或尾随空格。
7. 如果任何部分不起作用，请在运行报表时在SQL Server上运行跟踪，并仔细查看服务器上正在执行的操作。

我知道您会认为很多步骤都是不必要的，但要花些时间，至少可以肯定，您可以从调查中排除此类基本检查。
