Erza, thanks for your answer.<br>
<br>
Well, PostgreSQL is pretty flexible for managing sets and subsets.
Unfortunately, I cannot find a Bond way for an GUI end-user to
mark a subset of the list in Bond, so your fair explanation does
help to not solve the main problem.<br>
<br>
It seems that there is now way in current Bond to mark a subset of
some query result set (using Ctrl-click on the GTK+ tree widget or
so). Is it true?<br>
<br>
Thanks in advance.<br>

Hi Vladimir,
<div><br>
</div>
<div>I think what you may be looking for could involve using a
WITH clause in your SQL query:</div>
<div><a moz-do-not-send="true"
href="http://www.postgresql.org/docs/9.2/static/queries-with.html">www.postgresql.org/docs/9.2/static/queries-with.html</a></div>
<div>It's useful if you're trying to query a query.</div>
<div>For viewing it, I'd use a dynamic list (dynamic="true") in
Bond:</div>
<div>
<div><list dynamic="true" sortable="true"
name="myquery-outputs"></div>
<div> <dbobject name="myquery-outputs"></div>
<div> <sql></div>
<div> WITH (…)</div>
<div> SELECT (…) FROM (…)</div>
<div> </sql></div>
<div> </dbobject></div>
<div> <column title="?"></div>
<div> <field/></div>
<div> </column></div>
<div></list></div>
</div>
<div>I personally might shy away from using VALUES lists- fine for
having static values, but bad if you would ever want to change
it.</div>
<div>Another option-- if you're interested in still using VALUES,
or executing a dynamic query, I might recommend writing a
function in pl/pgsql that EXECUTEs a string as a query.</div>
<div><br>
</div>
<div>Does that help?</div>
