var joinItem=new SuperMap.REST.JoinItem({

foreignTableName: "V_ENABLEVIEW_LAND",

joinFilter: "BBS_PARCEL.CADASTRALNO = V_ENABLEVIEW_LAND.CADASTRALNO ",

joinType: "INNERJOIN"

});

var queryParam, queryByGeometryParameters, queryService;

queryParam = new SuperMap.REST.FilterParameter({

joinItems:[joinItem],

name: "[email protected]_sysdb",

fields: [

"BBS_PARCEL.CADASTRALNO as CADASTRALNO",

"BBS_PARCEL.POSTADDRESS as POSTADDRESS",

"BBS_PARCEL.BOOKAREA as BOOKAREA",

"BBS_PARCEL.REALAREA as REALAREA",

"V_ENABLEVIEW_LAND.FJBM as FJBM"],

displayFilters:["V_ENABLEVIEW_LAND.FJBM=‘"+_disCode +"‘ or V_ENABLEVIEW_LAND.FJBM is null "]

});

queryByGeometryParameters = new SuperMap.REST.QueryByGeometryParameters({

queryParams: [queryParam],

geometry: feature.geometry,

spatialQueryMode: SuperMap.REST.SpatialQueryMode.INTERSECT

});
