[Geoserver-users] Possible to update more than one feature within one same request?

Hi,

I understand we can do a <wfs:Update> to update the geometry field of a
particular feature with a filter:

<wfs:Update typeName = "prrm:vehicle_map">

                        <wfs:Property>

                                    <wfs:Name>the_geom</wfs:Name>

                                    <wfs:Value>

                                                <prrm:the_geom>

                                                            <gml:Point
srsName="http://www.opengis.net/gml/srs/epsg.xml#4326&quot;&gt;

<gml:coordinates>104.18235378265355,1.383478808</gml:coordinates>

                                                             </gml:Point>

                                                </prrm:the_geom>

</wfs:Value>

</wfs:Property>

<ogc:Filter>

<ogc:PropertyIsEqualTo>

<ogc:PropertyName>vehicle_number</ogc:PropertyName>

<ogc:Literal>SGD7575D</ogc:Literal>

</ogc:PropertyIsEqualTo>

</ogc:Filter>

            </wfs:Update>

My question is, is it possible to update the coordinates of more than one
feature within just one request? That is, suppose I have this set of data
consisting of three records [SGD7575D, 104.18235378265355,1.383478808],
[FZ8989L, 103.8617263193862,1.311391065], [GT1212A,
103.7945074844350,1.329840021] and I want to update all the features at the
same time. Is it possible to do it and how should I construct my request?

Would greatly appreciate any help/suggestions I can get. Thanks a lot.

You're updating each to a different set of coordinates? If you're updating all three to the same coordinate you can just use <Or> filters on the three values to match against.

If they're each their own update, you can do it all in one request, a Transaction can have multiple Insert, Update or Deletes. Just make the three different Updates, and put them one after another inside the transaction. GeoServer should update things atomically (if one fails then none of them go in), and all in one request.

best regards,

Chris
