Question

I have a cursor with a float value describing my people weight in kg.

So all my people in my database have this look:

NAME - WEIGHT:
John: 85.3
Michael:80.3
Lisa 58.2
Christopher: 75.0

What I want to do is to display them in a ListView by weight range.

"50-60": 1 people
"60-70": 1 people
"70-80": 2 people
"80-90": 0 people

I plan to use a ListView with a SimpleCursorAdapter, but I don’t know how to group them…

Thank a lot for your help

Answer 1

Something along the lines of:

select
sum(case when weight > 60 and weight <= 70 then 1 else 0 end) as weight1,
sum(case when weight > 60 and weight <= 80 then 1 else 0 end) as weight2
from myTable
