<div dir="ltr">Thanks Andreas,<div> I used a crude but effective workaround by selecting the polygon and then the points in the polygon and then doing a simple {case when "Variable" is NULL then 'String' else "Variable" end} for each polygon (I only had nine so it wasn't too much of a strain) and it worked fine.</div>

<br>
The "Vector" --> "Data management tools" --> "Join attributes by<br>
location" will also join attributes from the polygon layer - of course,<br>
depending on the spatial join, it will have to aggregate the data like<br>
you also have to in SQL if you have a 1:n relation - but you can also<br>
choose to use the attributes of the first hit.<br>
<br>
Other than that I do not think the field calculator allows to reference<br>
data from other layers.<br>
<br>
In QGIS 2.1 we will work on database relations. Although spatial joins<br>
are not the primary goal of this work, we may work on these as well.<br>
<br>
Hope this helps.<br>
