reporting

问题 I am using MySQL 5.x and there is one main table that has the stats combined for all customers. I would like to run reporting on it but dont want to run it on the same table so Im thinking of every night moving the data to a different table that will only be used for reporting.

For example - a single report, depending on who logs on (we know what company they belong

问题 I am a rank noob at any reporting but horizontal lines with sub-totals. I have a dataset that comprises the times spent by cars in a carpark. I must produce a table showing a column for each hour and a row for each day, showing the number of entries at a particular time on a particular day.

问题 I am developing web based application, i need php reporting lib/class to make the job easy. I need PDF/Excel format.

问题 Is it possible to reset the value returned by totalPages() method of reportRun class? I have one report populated with several invoices, I want to reset the totalPages() value for each fetched invoice. I tried to use element.reset() in the fetch() method of my report and it doesn't work, it splits my report by invoices. 回答1: No, it is not possible. The reset method does the trick, but splits the report as you observed. And unless your lines exactly fit one line there is no way to precalculate

问题 I am creating a report in Jasper with four parts. Each part consists of a text field as the header and a subreport. The subreport can be empty. If it is empty it is hidden using Remove Line When Blank . This works so far. Now, the corresponding header text field should be hidden too if the subreport is hidden.

问题 I am modifying an existing report which is setup to let you view statistics per sales rep. You do this by changing the parameter sales rep in the report view. I need to modify the report so that it can display a page for each sales rep. This will then be exported to Excel with each sales rep statistics being displayed in a separate tab.
