Additional Information

This is by design. The query expression does not take a IWorkspace object.


1. If using a connection string or property set to open the workspace using the connection information to create a connection file on disk and then utilize this connection path to execute the MakeQueryLayer tool. 2. Create the QueryLayer in ArcObjects without using the GeoProcessor as shown below: var factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.SdeWorkspaceFactory"); var wsf = Activator.CreateInstance(factoryType) as IWorkspaceFactory; var workspace = wsf.Open(propSet, 0) as ISqlWorkspace; var query = string.Format("SELECT {0} FROM {1}", "*", TableName); var queryDesc = workspace.GetQueryDescription(query); queryDesc.OIDFields = ObjectID; string name; workspace.CheckDatasetName(TableName, queryDesc, out name); var featClass = workspace.OpenQueryClass(name, queryDesc) as IFeatureClass;
