Hi Sven,
I think the filter accepts almost everything that SQL accepts - just the
WHERE part of an SQL query.
The manual doesn't discuss the rule-based renderer in detail. If you
have something to contribute, please contact the doc/community team.

Hi Sven
Each rule can also hold a scale range (min/max). You can have multiple
scale ranges per layer.
In your case, one rule would contain the intended scale range and the
filter (like an SQL-WHERE part). In the recent trunk there is also a
graphical query builder now.
The other rule would hold the consequent scale range and a different
filter/SQL-WHERE part.
To enable the rule-based renderer, choose "New Symbology" and then
"rule based renderer". There is a button with a green "plus" to add a
new rule. In the new dialogue you can then define a scale range and the
SQL where part.
Oh that looks great.
Then I have to update the trunk version to get the graphical query builder.
Is there also a description in the manual about how the filter queries have to
look like?
Thanks,
Sven
