problem with two key ranges in couchdb
- by Duasto
I'm having problem getting the right results in my coordinate system.
To explain my system, I have this simple database that have x_axis, y_axis and name columns. I don't need to get all the data, I just need to display some part of it.
For example, I have a coordinate system that have 10:10(meaning from x_axis -10 to 10 and from y_axis -10 to 10) and I want to display only 49 coordinates. In sql query I can do it something like this:
"select * from coordinate where x_axis = -3 and x_axis <= 3 and y_axis = -3 y_axis <= 3"
I tried this function but no success:
"by_range": {
"map": "function(doc) { emit([doc.x_axis, doc.y_axis], doc) }"
}
by_range?startkey=[-3,-3]&endkey=[3,3]
I got a wrong results of:
-3x-3
-3x-2
-3x-1
-3x0
-3x1
-3x2
-3x3
<-- should not display this part --
-3x4
-3x5
-3x6
-3x7
-3x8
-3x9
-3x10
<-- end of should not display this part --
..... up to 3x3
to give you a better understanding of my project here is the screenshot of that I want to be made: Oops they don't allowed new poster to post an image img96(dot)imageshack(dot)us/img96/5382/coordinates(dot)jpg <<< just change the "(dot)" to "."
