Hi all,
I'm having some problems with the new atlas SQL features and I feel like
a dumb.
before 2.6 I've been able to set the output name such as "feature id _
feature name", but I can't understand (or make it work) with the new
functions $atlasfeature and $atlasfeatureid.
indeed, once started with the atlas production, a temporary image is
created and then overwritten, leaving me with nothing.
I tried with:
$atlasfeatureid || '_' || attribute($atlasfeature, "name" )
and then
attribute( $atlasfeature, "id" ) || '_' || attribute( $atlasfeature,
"name" )
("id" is a numeric field within the table)
any suggestion?
thank you in advance!
all the best,
Nic
