Java Development Tools

I have a View created in JDeveloper to perform a query on a database view. The query works fine but I'm having issues with the sort. I use the Order By field to select the columns for sorting however I'm not getting the expected results.

My Data looks like this:

1
10
2
3

I need it to look like this:

1
2
3
10

Is there a way to correct this is JDeveloper or do I need to try and correct this on the view created in the Database? Any help would be greatly appreciated.

Thanks, scopley
