代码中的Crystal Report调用命令表 [英] Crystal Report Call Command Table in Code

问题描述

我需要在代码中调用命令，而不是对查询进行硬编码，以便即使在报告中添加了任何其他字段，我也不必在代码中进行更改..

I need to call the command in the code instead of hard coding the query so that even if any additional field is added in the report I dont have to make changes in the code..

SELECT * FROM employee
  WHERE emp_id='{?emp_id}'

推荐答案

看看这篇文章: ^ ]

就像其中显示的方式一样，您也可以在运行时为报表设置数据集.现在，由于您可以在运行时设置数据集，因此可以设置任何查询以获取该数据集结果.

Have a look at this article: Creating Crystal Reports using C# with Datasets[^]

Just the way shown in it, you can set the dataset at runtime too, for the report. Now, since you can set the dataset at runtime, you can set any query to get that dataset result.
