If you want to select those colums at code-time, then you should use a dynamicList which select fields from available entities, so if you want to use it, you might also want to map you database views (from which you will select some fields) to entities using the LLBLGen Pro designer.
Else if you want you may select and limit the fields in an Entity, typedList and TypedView at design time, using the LLBLGen Pro designer.
