<div class="moz-cite-prefix"><font face="Arial">Hi Carlos</font>, <br>
<br>
thanks for your input. I tried this before. However I am not able
to open *.dbf tables in Excel. It appears not to be readable in a
suitable form (Yes, I do go the way over right click, show all
files, open, and define seperators etc.). Somehow Excel does not
read the row break properly (when I try to import the pure data
without the header it tries to show all data in the first row and
aborts due to limited number of columns in Excel). I tried
different file origins (MacIntosh, Windows, DOS) as well. In a
German forum I found information that Microsoft does not support
*.dbf files anymore for Excel 2010 or higher which might explain
that issue.<br>
<br>
Btw: I am running QGIS 1.8 on a Mac OS X Version 10.7.5 (whom ever
this information helps) with MS Excel for Mac2011 Version 14.3.6
on it.<br>
<br>
I mentioned it before to Nathan already. All I want to do in the
end is to convert six categories so I can display them in
differing colors without creating new layers. But that is the way
I have to do it in the end I guess. <br>
<br>
Thanks for your replies and thanks for having me in the community<br>

<div>... or perhaps you can:<br>
<br>
0. Add the new column, acording type od data and length
and... save and close QGIS (no data added). <br>
1. Open the *.DBF table with LibreOffice Calc or MS Excel,
to take advantage of their functions<br>
2. Calc-Excel formulas would be taken as text, so you
have to overwrite them with their own results<br>
3. Save (as *.DBF).<br>
4. Open the shape in QGIS. It will have the new data.<br>
</div>
5. An "advanced" step 2 is add new columns directly in
Calc/Excel. For that, watch the headers: they have:
name_of_camp , type_of_data , lenght<br>
<br>
</div>
Good luck<br>

<div>This is currently not possible. If you are running
QGIS 1.9 you do have the ability to define your own
functions using Python example here <a

if you are new to Python and QGIS this isn't something I
would do right away.</div>

<div bgcolor="#FFFFFF" text="#000000"> <font

<br>
the QGIS world is new to me, so please be
gentle...<br>
<br>
I am wondering how I could combine field
calculator functions in order to convert
information from an existing data column into
a new one.<br>
What I can do with my mediocre knowledge is to
query information from column 1 by setting <br>
<br>
"column1"='abc' <br>
<br>
which gives me a binary result (0,1) in my
resulting column. Then I can <br>
<br>
replace ("newcolumn",'1','6')<br>
<br>
How could I combine these two into one working
function (i.e. there MUST be a simple
expression in the function list) and do not
lose the new number when querying another
information (e.g. 'cba') from column 1? <br>
<br>
Thanks in advance!<span><font color="#888888"><br>
