<div dir="ltr">Hey Micheal,<div><br></div><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 href="https://github.com/NathanW2/qgsexpressionsplus/blob/master/functions.py">https://github.com/NathanW2/qgsexpressionsplus/blob/master/functions.py</a> however if you are new to Python and QGIS this isn't something I would do right away.</div>

<font face="Arial">Hello QGIS users,<br>
<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 class="HOEnZb"><font color="#888888"><br>
