Hi,
Dealing with NULL values is better done with COALESCE() then with CASE
WHEN THEN ELSE END, as the COALESCE is shorter syntax and made for
dealing with NULL values.
But yes, you can concatenate any attributes.
The tricky part is getting different colors for parts of the label.
This is not yet possible. You may open a feature request for that.
Maybe we can introduce a markup language (HTML like syntax) for such
use-cases.
Can you open a feature request for this?
You can "sort of" simulate this by labeling the same layer twice, but
it may introduce additional complexity (overlap problems, etc.). So it
really would be better if we could have different colors within a single
label.

It is also possible to use conditions. Right now a label is not shown
if a single field is NULL.
So I´m using this expression:
Litra || 'n' || "Anvendelse" || 'n' || CASE WHEN "Anlaegaar" is NULL
THEN '' ELSE "Anlaegaar" END
(The '' after THEN is a double-ping)

EMNE: Re: [Qgis-user] Multiple attribute labeling point layers
Or.. you can do a expression based label:
"Field 1" || 'n' || "Field_2"
Result is label in two lines, with different fields. You can
concatenate more text with ||
... but color is same
Good luck

Hi Massimo,
Yes you can.
Only you need is you duplicate the layer and assign labels different
in each other.
Is it ok?
All the best,

Hi
In QGIS 2.0.1 I need to label a point layer to display attributes
stored in 2 different attribute fields.
I need to show them in different colors, and in a specific
position, such as one in the up right and one in the down right of
the point.
How is it possible to do this?
Thanks
MASSIMO
