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.
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.
Here is my query expression:
$queryExp = "('[TOWN]' == '007-042') AND ('[TOWN]' == 'Acton'))";
---Hardcoded for testing now, will eventually use variables
$pLayer->queryByAttributes("MAP_BK_LOT",$queryExp,MS_SINGLE); ----Query
statement
The data is in an ESRI File GDB. I am using MS4w 3.0.4m MapServer 6.0.2,
MapScript 6.1 for PHP
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.
Any ideas what's going wrong here?
