with this because MapGuide doesn’t currently doesn’t allow access

<p class=MsoNormal><span style='color:#1F497D'>One thing that occurred to me
when reading this RFC was that I’d like to see a mechanism to “page”
through results; similar to the LIMIT clause in MySQL. When displaying
result sets in a web environment, you often want to give the user a small set
of the data, and then page through the results N records at a time. I can
currently brute-force this, but it would be more efficient to handle this on
the FDO side, especially for providers where the underlying storage format has
optimized methods of dealing with it. The current enhancements would make
this more efficient to brute-force, but I wonder if adding parameters to the
initial selection (start record, number of results) would make this even more
efficient.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’d like to bring your attention to
RFC 26 ( <a href="http://trac.osgeo.org/fdo/wiki/FDORfc26">http://trac.osgeo.org/fdo/wiki/FDORfc26</a>
) which proposes to add a new Extended Select command with uses a Scrollable
feature reader. Basically, this takes what currently are custom commands in the
SDF, SHP, and recently SQLite providers and makes them generic FDO commands.
This will remove special case handling for applications that currently use
these and open the door for generic use by any application.<o:p></o:p></span></p>
