need expression for target date changed count the ID's?
Hi
I have table and field are Issue_ID Date_upload Target_date
->KPI chart by default in the date_upload field we need to compare maximum_date and maximum previous date.if maximum date and maximum previous dates in the Taget_date field are different then caluclate the count id's.
->On the same KPI chart if the user selects any two dates compare those two dates.if maximum date and maximum previous dates in the Taget_date field are different then caluclate the count id's.
Example:
Issue_ID Date_upload Target_date
01 01-01-2018 10-05-2018
01 03-01-2018 15-05-2018
02 01-01-2018 10-05-2018
02 03-01-2018 10-05-2018
03 01-01-2018 10-05-2018
03 03-01-2018 16-05-2018
In the above table if we select dates in the date upload field i.e., 01-01-2018 and 03-03-2018 then count is 2 because id 01,03 target dates are changed and id 02 target dates are not changed.
I need quires for the above requirements in the back-end level.
i have written quires in the front end level but the performance is slow and it is showing an error in the chart i.e., time out.
