Run the code and click on the map to search and display features that are 1500 meters from the point. Instead, the token will be passed in POST request body or through X-Esri-Authorization header. The result of this operation is either a feature set or an array of feature IDs (if returnIdsOnly is set to true) and/or a result extent (if returnExtentOnly is set to true). Query expressions in ArcGIS adhere to standard SQL expressions. The code below builds a query using input text. Query expressions in ArcGIS adhere to standard SQL expressions. Run the code and click on the map to search and display features that are 1500 meters from the point. Applications can perform server-side or client-side SQL, spatial, and statistic queries to access and display data from feature layers. My feature layer is about 150 points with attributes. Properties:Example:// Once the layer loads, check if the// supportsAdd operations is enabled on the layerfeatureLayer.when(function(){ if (featureLayer.capabilities.operations.supportsAdd) { // if new features can be created in the layer // set … Counties: In ArcGIS Desktop this is very easy, just go to select by location and then query the point feature layer to see when it intersects with the polygon feature layer. Query a FeatureLayer. When the features are returned, pass the results to the addGraphics function. var query = new esri.tasks.Query(); query.geometry = area.geometry; var counter = 0; var listOfSelectedFeatures; for (var j = 0; j < map.graphicsLayerIds.length; j++) { var currentLayer = map.getLayer(map.graphicsLayerIds); currentLayer.selectFeatures(query, currentLayer.SELECTION_NEW, function { counter++; if (counter == (map.graphicsLayerIds.length - 1)) { for (var k = 0; k < map.graphicsLayerIds.length; k++) { var layer … Here we create new graphics, define the symbol and popup template, and then add them to the graphics layer. Indicates the layer's supported capabilities.Example:// Once the layer loads, check if the// supportsAdd operations is enabled on the layerfeatureLayer.then(function(){ if (featureLayer.capabilities.operations.supportsAdd) { // if new features can be created in the layer // set … Build an app to perform either client-side or server-side SQL and spatial queries to access data. With hosted feature layers, you can do the following: Both the SQL filter selected and the spatial query will be applied so you should only see trailheads that have "Canyon" in their name. Also, I know that the feature exists, but is not appearing on the map. Working with Feature Layers in the ArcGIS API for JavaScript ... Query the layer Attribute queries select only features passing a WHERE SQL clause Spatial queries select only features passing a spatial filter Statistic queries returns statistics about the selected features Use the queryFeatures method to execute the query. Notice that only the features that match the query are displayed. You can perform client-side queries against features that are displayed in the view. Copyright © 2021 Esri. Build an app that displays feature layers in a 2D map. Run the code and click on the map to query and draw features that are 1500 meters from the point. and it works well. Define an addGraphics function that will be used later to accept the return values from a query and add the results to the graphics layer. // query all features from the oil and gas wells layer view.when(function { return wellsLayer.when(function { var query = wellsLayer.createQuery(); return wellsLayer.queryFeatures(query); }); }); At the end of the code in the main function, create a FeatureLayer and set the url to access and query the trailheads feature layer, and then create a GraphicsLayer and add it to the map. Currently I have used a Query Task by specifying the layer, the "where" statement, graphic symbol, InfoTemplate etc. The require function is used to load modules so they can be used in the main function. Log in to create and rate content, and to follow, bookmark, and share content with other members. For example, you use this syntax using the Select By Attributes tool or with the Query Builder dialog box to set a layer definition query . The input into the process is Query.A user provides input to the query. If the result of the SQL query entered returns a spatial column, the output will be a feature layer. Learn more about graphics in the documentation. You can perform client-side queries against features that are displayed in the view. Both client-side and server-side queries can contain a SQL expression and/or a spatial relationship operator. View live sample Download as a zip file Explore in the sandbox Description. Afterwards we zoom the map to the extent of the graphics. Query layers allow both spatial and nonspatial information stored in a database to be easily integrated into map service operations. Web feature layers (also known as feature services) are layers that are shared to support displaying, querying, and editing data on the web. Hosted feature layers are layers that have been published to ArcGIS Online. 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 a result extent (if returnExtentOnly is set to true).. These layers offer the most flexibility, scalability, and compatibility across ArcGIS. This input might include selecting features on a map, selecting a value from a list, or typing in a value. The queryIds method is used to query the feature layer and return the object ids for all the records that match the input query. This sample shows how to page through records in a table. Display the visible extent of a cluster’s features. capabilitiesObjectreadonly 1. Define an addGraphics function that will be used later to accept the return values from a query and add the results to the graphics layer. It's important to keep the module references and function parameters in the same order. For example, you can use whereto query all counties in the state of Washington from a layer representing U.S. Create a feature layer for the trailheads so you can execute queries and a graphics layer to draw the features returned. Add a simple popupTemplate to each graphic to show some trail information when they are clicked. Indicates the layer's supported capabilities. Update the view.when and view.on handlers to call the queryFeatureLayerView function and pass in the same parameters. Now that the layer is created and we can add graphics, add code to execute the server-side query. A query table is a feature class or table defined by a SQL query on the fly. This input might include selecting features on a map, selecting a value from a list, or typing in a value. Beyond spatial queries, you can also perform an attribute or a combination of attribute and spatial search queries with the queryFeatures function. Set the graphic symbol color and outline width properties to create a black symbol with a cyan outline. Here we create new graphics, define the symbol and popup template, and then add them to the graphics layer. Run the code and click on the map to query and draw features that are 1500 meters from the point. Beyond spatial queries, you can also perform an attribute or a combination of attribute and spatial search queries with the queryFeatures function. To query features based on attribute values, specify a SQL where clause in the where property. Function. Since the data is on the client, client-side queries execute very quickly.

When the view is ready, call the queryFeatureLayer function and pass in the center of the view, 1500 as the distance in meters, and intersects as the spatial relationship operator to use. Another form of querying is to use the hitTest method on the view to find features at a given screen location. Define another function that accepts a point, distance to search, spatial relationship operator, and an optional SQL expression and builds a query that will return all of the fields and the geometry from the feature layer. 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.
