The count shows non zero value in reports on a table created using 'Database view'

[Rama Chandra D]

Hello everyone,

I have created a 'Database view' to join Problem and associated Problem task table to run a report that displays all the open problems along with their tasks if any. The Database view runs well so does the report. However, when I group the report using 'Problem Number' it shows the count against each problem with no tasks as '1' and when expanded it shoes 'empty' in all the fields. I was expecting that count would be zero if there are no tasks associated with the problem.

Is there any way, I can avoid the misleading count of '1' when there are no tasks?

I think you don't even need a database view for what you are trying to achieve

Here is the sample one on change request

For your case create a report on problem task and group by problem field

Hi dvp,

Thanks for the reply. Let me try and get back to you on this.

Edit : I've tried as per your suggestion but the report doesn't contain Problem without any task as the report is run on 'Problem Task' table.

Yes, that's because the Problem Task [problem_task] table is based on a JOIN, not a LEFT JOIN.

I like the solution dvp is suggesting. But if you'd like fix your view, my feeling is you may be using a LEFT JOIN instead of JOIN. If you simply change the JOIN type, then you won't see any problem records with no tasks. If you can share a screenshot of your view definition, I can pinpoint if that's the case.

Hope this helps.
