<div class="WordSection1">
<p class="MsoNormal">I am trying to set up an attribute query for a large parcel dataset (about 550,000 polygons). I am having trouble with the query exceeding the 30 second limit.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to query on the map_bk_lot and town attributes. I can query on either one separately and get results, but I need to query on both at the same time.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here is my query expression:<o:p></o:p></p>
<p class="MsoNormal">$queryExp = "('[TOWN]' == '007-042') AND ('[TOWN]' == 'Acton'))"; ---Hardcoded for testing now, will eventually use variables<o:p></o:p></p>
<p class="MsoNormal">$pLayer->queryByAttributes("MAP_BK_LOT",$queryExp,MS_SINGLE); ----Query statement<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The data is in an ESRI File GDB. I am using MS4w 3.0.4m MapServer 6.0.2, MapScript 6.1 for PHP<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One other thing worth mentioning- if I use a small subset of features (such as a town), the query will work without timing out. But I’m no longer convinced that dataset size is the problem since it will query on one attribute.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any ideas what’s going wrong here?<o:p></o:p></p>
