Thanks Steve! Great explanation!<br>But, in mapscript I got the query´s result getting resultCacheMemberObj and layer.getFeature...<br>How can I do something like that using cgi? <br><br>Paul<br><br><br><div class="gmail_quote">

Querying is controlled via the mode parameter. Mode=query does a point query returning at most 1 result in one layer. Mode=nquery allows you<br>
to query multiple layers and return multiple results from either a point or a rect. MapServer looks at the various additional supplied parameters to<br>
decide whether to do a point or rect query.<br>
<br>
For example, this url will drop a point through all queryable layers that have status DEFAULT (since I'm not explicitly turning anything on)<br>
<br>
<a href="http://mapserv.org/cgi-bin/mapserv?map=foo.map&mapxy=x+y&mode=nquery" target="_blank">http://mapserv.org/cgi-bin/mapserv?map=foo.map&mapxy=x+y&mode=nquery</a><br>
<br>
and this will do a bbox query:<br>
<br>
<a href="http://mapserv.org/cgi-bin/mapserv?map=foo.map&mapext=minx+miny+maxx+maxy&mode=nquery" target="_blank">http://mapserv.org/cgi-bin/mapserv?map=foo.map&mapext=minx+miny+maxx+maxy&mode=nquery</a><br>
<br>
You can turn layers on with the layer or layers parameters and can restrict queries to one layer (if necessary) using qlayer.<br>
<br>
mode=query ~ queryByPoint with MS_SINGLE<br>
mode=nquery ~ queryByPoint with MS_MULTIPLE or queryByRect<br>
<br>
The qlayer parameter has the effect of running the query methods on a layerObj while without it you're running on the whole mapObj.<br>
<br>
Does this help?<br>
