Should unlimited filtering be offered to users?

I'm working on a project with a page where users can build their reports dynamically.

We have a listbox.... user selects from values from it. These are the columns for the Excel report

Next, user can build the where-clause. These are textboxes. For example.... textbox1 = some value (they type this). Now, this is unlimited. User can click on a button, and create another clause. We AND them together. There's no limit.

I think there should be a limit to this. Maybe 5 to 10. My manager says there shouldn't be a limit. He gave an example...in TFS...user can create as many query where-clause as they want. Here's an example Example

So, should there be a limit  in where-clause when we create a SQL for reporting and the report is dynamic?

Hi,

Personally, I think your manager is right, unless your application cannot handle it, in which case you may have to hobble it.

Even more important, offer the user the ability to download a nice clean structured data file (CSV preferably, Excel format second best) with no extraneous info (report name, date run etc) - just the field names, and the data, without having to select every field individually.

That way, your report system won't stop users actually using the data in the way they need.


Hope that helps,

Alan.
