在数据库已连接时，是否需要添加数据集或数据表才能生成水晶报告？ [英] Do I need to add dataset or datatable when a database is already connected, to make crystal reports?

问题描述

我正在用C＃做一个VS项目，我正在与Crystal Reports挣扎。我已经有一个连接到该程序的SQL数据库，现在我正在尝试使用该数据库生成报告。我已经阅读了其他论坛，了解如何创建Crystal Reports，他们似乎都提到了添加数据集或数据表。当我使用Crystal Report向导时，它会向我显示我需要的所有表。那么我是否还需要为报告添加数据集才能使用，或者我是否可以使用我在数据库中已经可以在向导中看到的表格？我帮助解决这个问题，因为我的项目是星期一到期的，并且报告确实让我回头了



我尝试了什么：



我试图添加我已经看到的表，而不添加新的数据集或数据表。信息似乎到处都是，但它就在那里。也许我应该直接使用存储过程而不是表格

I'm doing a VS project in C# and I'm struggling with Crystal Reports. I already have an SQL database connected to the program and am now trying to generate reports using the database. I have read through other forums on how to create Crystal Reports and they all seem to mention the addition of a dataset or datatable. When I use the Crystal Report wizard, it shows me all the tables I need. So do I still need to add a dataset for the report to work off of or can I use the tables from my database that I can already see on the wizard? Please assist me with this issue as my project is due Monday and the reporting is really setting me back

What I have tried:

I have tried to add the tables I already see, without adding a new dataset or datatable. The information seems to be all over the place but it is there. Maybe I should use the stored procedures instead of the tables directly

推荐答案

嗯，你可以，但你没必要，因为你可以动态地做到这一点 - 通过代码;）

Well, you can, but you don't have to, because you can do it in dynamic way - via code ;)
