Selecting events and routes by attribute

Use the Select Events by Attribute widget in the ArcGIS Event Editor web app to select events, routes, or point features on a map by querying the layer's attributes. This method of event selection uses Structured Query Language (SQL) WHERE clauses to select events on the map using one or more criteria.

For example, if you want to select all the events within Route 10054101 that have a speed limit greater than or equal to 40 miles per hour, write an SQL expression such as "Route_ID" = '10054101' AND "Speed_Limit" >= 40.

    The results are shown in a tabulated format. In this example, all the records in the SpeedLimit layer with a Route_ID of 10054101 and a speed limit greater than or equal to 40 miles per hour are highlighted on the map.

Once the event or point feature records are selected, browse to and edit them using the results grid.
