This should work:
DataAccessAdapter adapter = new DataAccessAdapter();
ResultsetFields fields = new ResultsetFields(1);
fields.DefineField(ArticleFields.ManufactureCode, 0);
IRelationPredicateBucket bucket = new RelationPredicateBucket();
bucket.Relations.Add(ArticleEntity.Relations.VehicleEntityUsingVId, JoinHint.Inner);
DataTable dynamicList = new DataTable();
adapter.FetchTypedList(fields, dynamicList, bucket, 0, null, false, null);
I'm assuming a few things here:
-You are using LLBLGen 2.5
-You are using Adapter
-The ManufactureCode field belongs to the Article Table
-And of course, the naming of the mapped tables and fields in your project.
