Hi all, I have a Feature-Layer pointing to an Oracle Table (user-maintained rowid) with spatial type "SDO_GEOMETRY". The Oracle Table is not SDE-registered. By both loading the table from ArcCatalog into ArcMap or using ArcTool MakeQueryLayer I get a layer with data type "Query Feature Class". Map operations e.g. zooming, panning, selecting etc. work. My issue is changing the data source programmatically (c#, ArcMap 10.3) either results to exceptions or a layer with data type "Feature Class" and consecutively drawing errors in ArcMap when loading additional layers and executing map operations e.g. zooming, panning, selecting etc: Drawing errors also occur when I create this layer by ArcTool MakeFeatureLayer although when loaded stand-alone, i.e. no additional layer are load in TOC, map operations e.g. zooming, panning, selecting etc. work without any errors. Input: IFeatureWorkspace featureWS (cast from IWorkspace with Type = esriRemoteDatabaseWorkspace) Input: IFeatureLayer pFeatureLayer DataSourceType: Query Feature Class FeatureClass: with AliasName "schema1.%Table1" (what does the character "%" mean ?? / where does this character come from ?? My table's name is "schema1.Table1" !!) #region Alternative 1: IQueryDef => System.Runtime.InteropServices.COMException (0x80050140): Abstract Data Types not supported IQueryDef queryDef = featureWS.CreateQueryDef(); queryDef.Tables = "schema1.Table1"; queryDef.SubFields = "*"; queryDef.WhereClause = string.Empty; IFeatureDataset pFeatureQuery = featureWS.OpenFeatureQuery("Table1", queryDef); pFeatureLayer.FeatureClass = pFeatureQuery as IFeatureClass; #endregion #region Alternative 2: ITable zu IDataset => Data Source Type = FeatureClass => Drawing Error in ArcMap ITable table = featureWS.OpenTable("schema1.Table1"); IDataset dataSet = table as IDataset; pFeatureLayer.FeatureClass = dataSet as IFeatureClass; pFeatureLayer.DataSourceType = "Query Feature Class"; #endregion So my question is how to change programmatically the data source (FeatureClass-property) of IFeatureLayer with DataSourceType = "Query Feature Class" in ArcMap 10.3 avoiding the change of DataSourceType, any exceptions and drawing errors ? Any help is appreciated !
