Bug report #11391

select by expression on numerical field doesn't give expected results

Add a layer with an integer field (let's call it "id")
select features with "select by expression" tool, using an expression like "id" > 10 and "id" <20
the selected features have id like 11, 12 ... but also 112, 185... and 2.
Selecting features with toint("id") > 10 and toint("id") <20 only selects features between 11 and 19. What is expecting.

It looks like QGIS doesn't recognize field type as numerical. my integer field "id" is used like a string one.
I just find that it is the same behavior with QGIS 2.4

I cannot confirm on qgis master.

Please attach sample data.

I give it another try. It works fine with shapefiles but not with postgis table (the one I used before) when the searched field is the primary key.
Can you test again, please?
