arcgis rest feature layer query

The feature service layer Query operation supports the returnTrueCurves, historicMoment and sqlFormat parameters. "layerTimeOptions": // optional For percentile statistics, there are two statisticTypes, PERCENTILE_DISC (discrete) and PERCENTILE_CONT (continuous). You use the New Query Layer dialog box in ArcMap to create query layers. May be set for feature layers inside a feature collection item. This sample shows how to page through records in a table. The Query operation is performed on a feature service resource. You may also be able to edit the data represented by the feature layer. From 10.0 onward, the query operation can be performed on tables and layers. Some sample … For more information on datum transformation, please see transformation parameter in Project operation. This parameter only applies if returnGeometry is true. The result of this operation is either a feature set for each layer in the query or a count of features for each layer (if returnCountOnly is set to true) or an array of feature IDs for each layer in the query (if returnIdsOnly is set to true). A possible use case might be on a feature table marking the location of street furniture through a city. "type": "dataLayer", Envelope intersect —The envelope of layer 1 intersects with the envelope of layer 2. If the query results include an empty feature set, the fields set is not returned. For example, in a set of 10 values from 1 to 10, the percentile value for 0.9 with orderBy set as ascending (ASC) is 9, while the percentile for value 0.9 with orderBy set as descending (DESC) is 2. The default spatial relationship is intersects (esriSpatialRelIntersects). This option was added at 10.1 SP1. "showLabels": , Description: The sqlFormat parameter can be either standard SQL92 standard or it can use the native SQL of the underlying datastore native. The spatial reference can be specified as either a well-known ID or Otherwise, z-values are not returned. If you don't need to edit the data in a specific map, disable editing for the layer … The layer resource represents a single feature layer or a non-spatial table in a feature service. This feature set contains orderByFields defaults to ASC (ascending order) if is unspecified. For more information on this spatial relate function, refer to the documentation for the spatial relate function. Query using the text parameter on a dynamic layer based on an existing layer: When returnIdsOnly=false and returnCountOnly=false, When groupByFieldsForStatistics and outStatistics are specified, Copyright Â© 2020 Esri. the map. This operation is supported at 10.1 and later. A feature layer is a table or view with at least one spatial column. The records can contain attribute and/or geometry information. typeIdField Optional: string: Contains the name of the field holding the type ID for the features. Query expressions are used in ArcGIS to select a subset of features and table records. The layer query operation supports percentile as a statisticType when using outstatistic for hosted feature services in ArcGIS Online or ArcGIS Enterprise when run on a relational data store. Streaming feature layer—Configure streaming layers in ArcGIS GeoEvent Server and add the service to ArcGIS Online. The queryIds method is used to query the feature layer and return the object ids for all the records that match the input query. For this reason you should always rely on the exceededTransferLimit property to determine if you should page through results rather than relying on the number of results returned from each page. When set to true, returns true curves in output geometries. Feature services are created and hosted by the SDS and contain feature layers which represent spatially enabled tables or views. SQL 92 where clause syntax on the fields in the layer is supported for most data sources. In some cases when using the resultOffset and resultRecordCount parameters, the exceededTransferLimit property may be included in the query results even though the value specified in the resultRecordCount has not been exceeded. The result of this operation is either a feature set for each layer in the query or a count of features for each layer (if returnCountOnly is set to true) or an array of feature IDs for each layer in the query (if returnIdsOnly is set to true). { "" : "" , "" : "" }, {"0":"POP2000 > 1000000","5":"AREA > 100000"}, [{ "layerId" : ,"where": "", "outfields": ","},{"layerId" : ,"where": "", "outfields": ","}], [{"layerId" : 0, "where" : "OBJECTID<100", "outFields" : "*"}, {"layerId" : 1, "where" : "OBJECTID<323", "outFields" : "OBJECTID,CREATOR"}], geometryType=esriGeometryEnvelope&geometry=,,,, geometryType=esriGeometryPoint&geometry=,, geometryType=esriGeometryEnvelope&geometry={xmin: -104, ymin: 35.6, xmax: -94.32, ymax: 41}, geometryType=esriGeometryEnvelope&geometry=-104,35.6,-94.32,41, geometryType=esriGeometryPoint&geometry=-104,35.6, esriGeometryPoint | esriGeometryMultipoint | esriGeometryPolyline | esriGeometryPolygon | esriGeometryEnvelope, esriSpatialRelIntersects | esriSpatialRelContains | esriSpatialRelCrosses | esriSpatialRelEnvelopeIntersects | esriSpatialRelIndexIntersects | esriSpatialRelOverlaps | esriSpatialRelTouches | esriSpatialRelWithin, historicMoment=, , returnIdsOnly=false, returnCountOnly=false, "Andreanof Islands, Aleutian Islands, Alaska". The result of this operation is a feature set. Description: Optional parameter which is false by default. The object IDs of this layer or table to be queried. The features only return a set # but the IDsOnly query returns everything. https://services.myserver.com/OrgID/ArcGIS/rest/services/PoolPermits/FeatureServer/query?layerDefs={"0":"Has_Pool=1 AND Pool_Permit=1","1":"Has_Pool=1 AND Pool_Permit=1"}&returnGeometry=true&f=html.

"drawingInfo": // optional If true, m-values will be included in the results if the features have m-values. After you create a query layer, you can save it … A definition expression for a layer that is published with the service will always be honored. For tables, it provides basic information about the table such as its ID, name, fields, types, and templates. When using outSR with pbf, the pbf format will use coordinate quantization for layer queries. "workspaceId": "MAP", Syntax: { You can provide arguments to the query operation as query parameters defined in the parameters table below. specify the geometry with a simpler comma-separated syntax. This option was added at 10.3. The query operation is performed on a dynamic layer/table resource. This list is a comma-delimited list of field names. Copyright Â© 1995-2019 Esri. As a service editor, ArcGIS Pro supports a wide range of geodatabase datasets and capabilities from supported databases. You can then further filter by Date Modified, Date Created, and Tags. = DATE 'YYYY-MM-DD' = TIMESTAMP 'YYYY-MM-DD HH:MI:SS' When should you use each type of date-time query? All you need to do is pass in the SQL where clause, and the service returns the records. Each type of date-time query must include a date function to make sure the query is treated in the proper way. The response format. Description: The historic moment to query. Description: This option can be used to specify the maxAllowableOffset to be used for generalizing geometries returned by the query operation. This operation is supported at 10.1 and later. For tables, it provides basic information about the table such as its ID, name, fields, types, and templates. Each featureset contains Feature objects including the values for the fields requested by the user. The percentile statisticType is supported if the supportsPercentileStatistics layer property (in advancedQueryCapabilities) is true. I ran a test and using where:1=1 I got 2,500 responses. This option was added at 10.3. One or more field names or expressions that the features/records need to be ordered by. The result of this operation is a feature set. If multipatchOption = stripMaterials, the multipatch geometry will be returned without materials (i.e. These techniques form the building blocks to … Your data must meet these requirements in addition to the requirements common to geodatabases and databases.. type Optional "Feature Layer" | "Table" Indicates whether the layerDefinition applies to a Feature Layer or a Table. } Syntax: [{ "layerId" : ,"where": "", "outfields": ","},{"layerId" : ,"where": "", "outfields": ","}] where layerId1, layerId2 are the layer IDs returned by the feature service resource, Example: [{"layerId" : 0, "where" : "OBJECTID<100", "outFields" : "*"}, {"layerId" : 1, "where" : "OBJECTID<323", "outFields" : "OBJECTID,CREATOR"}]. Before you can create a query layer, you must first make a connection to a database.The Connection drop-down list shows available database connections.. After a connection to the database is established, a list of tables and views found in that database populates the left window of the dialog box. A user may wish to query by a TYPE column to return "benches". Scene Viewer. Note that all parameters related to geometry will be ignored when querying tables. The list of fields to be included in the returned result set. You also learned how to filter a feature table to show a map that contains only the results that match a specific query string. This parameter only applies if returnGeometry is true, and at least one of the layer's hasZ property is true. If outSR is not specified, the geometry is returned in the spatial reference of the map. This parameter applies only if the layer is archiving enabled and the supportsQueryWithHistoricMoment property is set to true. Otherwise, the response is a feature set. geometry is assumed to be in the spatial reference of The query will show all the features from the layer you selected which meet the criteria you build in the Query Builder. In this case, the property will be true only if the { The maxAllowableOffset is in the units of the outSR. The spatial reference can be specified as either a well-known ID or as a spatial reference json object. Not having any success with basic Text or Geometry queries. This parameter cannot be used when returnGeometry is true. Otherwise, m-values are not returned. This option can be used to specify the number of decimal places in the response geometries returned by the query operation. Description: If true, Z values are included in the results if the features have Z values. For layers, if you request geometry information, the Solved: I am trying to query a feature layer as described here: arcgis.features module — arcgis 1.4.2 documentation but I get KeyError: 'count' (see full error In some extreme cases zero results can be returned, but the exceededTransferLimit property will be returned. Description. There might be a drop in performance if the layer or table data source resides in an enterprise geodatabase and more than 1,000 objectIds are specified. Clients can exploit this to get all the query conforming object IDs by specifying returnIdsOnly=true and subsequently requesting feature sets for subsets of object IDs. A simple library that can download a layer from a map in an ArcGIS web service and convert it to something useful: GeoJSON. The FeatureLayerView provides access to a layer's features that are displayed in the view.This sample uses the whenLayerView() method to get the FeatureLayer's layer view once it's created.. view.whenLayerView(featureLayer).then(function (lyrView) { // do something with the lyrView}); Once the layer view is available, you need to set up a watch on the updating property of the layer view. The spatial relate function that can be applied while performing the query operation. New at 10.6. At 10.4, expressions are allowed in addition to field name. "id": 101, You can also use a JSON representation for Layer Definitions. The default is true. Syntax: { "" : "" , "" : "" } where layerId1, layerId2 are the layer IDs returned by the feature service resource, Example: {"0":"POP2000 > 1000000","5":"AREA > 100000"}. This parameter applies only if the supportsReturningQueryExtent property of the layer is true. For example, when querying counties in the United States, you want to return the top five counties by population in each state. The query operation is performed on a feature service layer resource.The result of this operation is either a feature set or an array of feature IDs (if returnIdsOnly is set to true) and/or result extent (if returnExtentOnly is set to true).. If true, the result set includes the geometry associated with each result. If multipatchOption = xyFootprint, the xy footprint of each multipatch geometry will be returned in the result. "scaleSymbols": , Otherwise, M values are not returned. results. This option was added at 10.5 and works with ArcGIS Server services only. esriTimeUnitsMonths | esriTimeUnitsSeconds | esriTimeUnitsWeeks | esriTimeUnitsYears | The spatial reference of the returned geometry. The orderBy statistic parameter can also be used to calculate the percentile. Values: esriSpatialRelIntersects | esriSpatialRelContains | esriSpatialRelCrosses | esriSpatialRelEnvelopeIntersects | esriSpatialRelIndexIntersects | esriSpatialRelOverlaps | esriSpatialRelTouches | esriSpatialRelWithin. The layer query operation supports percentile as a statisticType when using outStatistics for map services published from ArcGIS Pro that reference enterprise geodatabase data. For example, spatiotemporal based feature services support the like operator but do not support the not like operator or field equivalency expressions like field1 = field2. Querying annotation is supported at the layer level, however querying annotation at the sublayer level is not supported. The query operationcan now return only the object / feature IDs in addition to returning a featureset.
