问题 I have a table of transactions which will occasionally have duplicate entries. If/When an admin finds these duplicate entries, they will reverse the transactions, therefore creating a negative value (but the original duplicate still remains due to regulatory requirements). I'd like to create a SQL query (and use Crystal Reports) to make a report for the admins to easily find duplicate transactions. Due to the mass quantity of transactions, I'd like to make it easier for them by disregarding

问题 I am working on a ASP.net application written in C# with Sql Server 2000 database. We have several PDF reports which clients use for their business needs. The problem is these reports take a while to generate (> 3 minutes). What usually ends up happening is when the user requests the report the request timeout kills the request before the web server has time to finish generating the report, so the user never gets a chance to download the file. Then the user will refresh the page and try again

问题 How would you "unit test" a report created by some report engine like Crystal Reports or SQL Server Reporting Services? 回答1: The problem with reports is akin to the problem with GUIs. If the Report/GUI has lot of (misplaced) intelligence it is going to make testing difficult. The solution then is to Separated Presentation : Separate presentation from content (data-access/domain/business rules). In the current context would mean, that you create some sort of ViewModel class that mirrors the

问题 We are trying to use PowerBi to build tabular reports from data in Azure DevOps. In this report, we want to display the description field in one of the table's columns. ADO stores the description as HTML. Neither PowerBI or Excel can render this content, but instead show the markup code. I've also looked at pulling this into python and using Dash with no luck. There is an extension for ADO that renders html, but it displays a single record and doesn't work as a table cell renderer. The output

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . A design question. I have developed an online test engine web app earlier this year. I have used Java servlets and Freemarker templates and done it entirely following the MVC paradigm. One big missing feature in the application is that it provides no reporting. The initial design of the application did not

问题 I have looked around a bit but I can't find a tool that fit my needs. What I need is a tool that allows users to create their own reports preferably from a web interface where the user is able to create charts, diagrams and tables . Therefore the tool needs to be able to handle several users and restrict the users to a certain database . I have looked at Crystal Reports and SSRS and neither of them seems to support what I want or am I missing something? 回答1: So, you're looking for a web-based

问题 I have a wcf webservice that uses WIF for authentication. Part of the responsibility of this webservice is to generate a report and email it. If I render the report with data only everything is fine.
