在2010年在Winforms中的Crystal Reports上加载大数据 [英] Loading Large data on Crystal Reports in winforms in 2010

问题描述

我有一个应用程序，其中我在Crystal报表上显示大量数据，但是该报表要花费太多时间来加载所有记录，如何才能最大程度地减少在报告中或在一两秒钟内加载整个记录的时间.

在此先谢谢您.

推荐答案

如果您的报告需要显示所有数据，那么除了做显而易见的事情之外，实际上没有其他方法可以加快它的工作-为数据库建立索引表和优化查询.但是，如果要显示的是数据的子集，则可能需要编写一个查询，该查询仅将所需的数据集作为存储过程来获取，并将其用作数据源.

If your report needs to display all the data, then there is really no way you can speed it up beyond doing the obvious - indexing your DB tables and optimizing queries. However, if it is a subset of data that you want to display, you may want to write a query that will only fetch the required data set as a stored procedure and use that as your data source.
