<p>Hi Paolo,</p>
<p>I asked the same question, but apparently there are technical
reasons.</p>
<p>The Query builder creates a query that a data source can
understand (e.g. OGR) - data is filtered at its source.</p>
<p>Whereas the expression builder is much, much richer and can't be
translated to filters of data providers. Thus, such data filtering
can only be done in the client - means that all features are
requested from the source and then filtered client side.</p>
<p>I don't know if it would be technically possible to restrict the
expression builder to a subset that a data provider can understand
- so that the user can have just one interface, both with a
limited set of operators and functions.<br>

<pre wrap="">Hi all,
the two dialogs are quite different, whereas they do essentialy the same
thing. Questions:
* is there a specific reason why the Query builder has not been updated,
or is it just the usual lack of time?
* is anyone planning to work on this?
Thanks.
