Thanks to you and Bernd for the tips ! I still hope someday these
features will be also available in the attribute editing table, this
seems more intuitive to me ...

Hi Leyan,
Are you aware that there is a tool in the advanced editing toolbar
called "Merge attributes of selected features". There are two
identical icons next to each other. One also merges the geometries
into one feature, the other one only sets all attributes of the
selected features to the same attributes. It assigns the same
attribute values to all features (except the primary key column). It
allows you to set which of the selected features is used or you can
calculcate mean/max/min or the most common attribute value.
Hope this helps,
Andreas

Hi Nathan,
I know the field calculator and used it quite extensively. The
functions are powerful but it can be quite cumbersome to use (I hope
the future saved expressions can help for this, having to copy and
paste from an external text editor is a pain). I would like to be able
to:
* sort according to several columns
* auto-increment a field just by dragging the mouse like in a
spreadsheet
* for a numeric field, see quickly the basic statistics of the
selected features (average, sum, maybe also min and max). Currently, I
would have to go to Vector->Analysis->Basic statistics and select the
field. I prefer to copy and paste the selected features to either
LibreOffice or Excel and select the column I want to see the sum, but
I don't know what to say each to people when I show them how to use
QGIS (we work on networks so we are often interested in the length of
lines in a selected area for example).
* select several cells and copy/paste them
* hide columns temporarily
* having formulas that stay as formulas and are updated when the
source data is updated, be it other fields, geometry, etc. ( I think I
saw something about this but I do not know the current status)
Anyway, just a few ideas I had in mind, probably more would come
later. I wanted to implement the basic statistics of selection myself,
but am I not sure of where to put this, there is no status bar.

Leyan,
What kind of stuff were you after? QGIS does have a field calculator
which can do expressions for calculations.

Install MultiEdit
Hi Ben,
If you work with shapefile, you can open the dbf file with LibreOffice
and do more advanced editing here. Be careful not to delete or reorder
lines. I agree it would be very nice to see these features included in
the attributes editing.

Hi All,
A couple of questions re editing data in the attribute table:
1) Is it possible to add/change attribute data to multiple selected
items in one single operation (I'm presently selecting the items,
opening the attribute table, ticking show selected only, and then
manually pasting the relevant data into the row for each item)?
Surely there is a more intelligent way to do this?
2) Is there a "find and replace" tool that can be used to change
matching data to a new value when editing data in the attribute table?
3) The MultiEdit plugin
(http://plugins.qgis.org/plugins/MultiEdit/) sounds like it may be
helpful when editing data in the attribute table but I haven't been
able to install it (it doesn't appear in the list of plugins in the
plugin installer). How do I install this plugin?
Thanks for your help,
Ben
