delphi - ReportBuilder 15 with Delphi XE4: Reports are empty

Question

I am migrating my code from Delphi 7 (ReportBuilder 12) to Delphi XE4 Enterpirse (ReportBuilder 15). To my wonder, when I click on Preview button to see load the reports, reports are appearing empty while in delphi 7 reports are showing data.

I don't think there is any error with code because its running fine there in Delphi 7. Is there any setting/configuration missing on my end? What and where should I check for it?

Answer 1

这是您在这里所做的一个相当大的版本飞跃：Delphi 7 到 XE4 和 RB12 到 RB15！

我会用调试信息编译 Reportbuilder15 并跟踪 RB 中发生的事情，因为我认为有很多地方发生了变化，几乎不可能找到一个特定的地方来查看。

Answer 2

这不是报表生成器问题，而是数据库问题。事实上，我迁移到 Delphi XE4 的应用程序无法从数据库中提取数据，这就是报告显示为空的原因。
