How to display layer the appropriate map query???

AhmadSopian1 · ‎12-15-2016

this is code query geodatabase in .NET Program

 
 DataTable dt;
 cmd.CommandText += "SELECT * FROM BUILD ";
 cmd.CommandText += "WHERE (((REL_PLANING_DATE - CURRENT_DATE)<61 And (REL_PLANING_DATE-CURRENT_DATE)>=0)) ";‍‍‍‍‍‍‍‍‍‍‍‍

this is code arcgis javascript api

Ahmad,

The JS API is not always comparable to a .NET program. Dot NET has direct access to ArcObjects and databases. You can not use relationship field in a FeatureLayers definition query. Your access to related data is limited to what is documented in the API.
