arc-jsapi How can I st_geometry using a lookup field?
I am using the st_geometry field and try to view the PNU code value.
I tried two ways.
1. oracle DB query.
select a.pnu from LP_PA_CBND_4600000000 a
where sde.st_contains(a.shape,
sde.st_point(177566.6728471977,160430.12935426735, 4))=1
When an event occurs, click the map object
i got the evt.mapPoint(x,y).
4 is my srid.
this way is took a long time. and query was down...
2. i used the arcgis api`s IdentifyParameters
my code is follows.
PoiClick : function(map, evt) {
G_evt =evt;
console.log("ClickPoint ==== "+evt.mapPoint);
var targetLayerId = 'LP_PA_CBND';
var url = map.Layers.getLayerInfo(targetLayerId).SVC_URL;
var map = map.getMap();
//파라미터 설정.
var idParams = new krcgis.core.tasks.IdentifyParameters();
G_idparams =idParams;
idParams.geometry = evt.mapPoint;
idParams.mapExtent = map.extent;
idParams.returnGeometry = true;
idParams.tolerance = 3;
idParams.layerOption = krcgis.core.tasks.IdentifyParameters.LAYER_OPTION_ALL;
idParams.width = map.width;
idParams.height = map.height;
krcgis.Function.GetPoiInfo(url, idParams);
return evt.mapPoint;
},
//POI 정보를 가져온다.
GetPoiInfo : function(url, idParams) {
idTask = new krcgis.core.tasks.IdentyfyTask(url);
idTask
.execute(idParams)
.addCallback(function (response) {
G_response = response;
if (response) {
return response;
}
})
.addErrback(function (error) {
console.log('GetPoiInfo result error=', error);
});
}
It could be obtained in this way code pnu.
However, this way is different from the value that gets pnu code depending on the zoom level.
I want to get a single pnu code in a single x, y values.
how to get pnu code?
