Each SqlLoader uses a SqlLoader.Columns to maintain a collection of SqlLoaderColumn objects. The SqlLoaderColumn object represents the attributes for column loading. Every SqlLoaderColumn object corresponds to one of the table fields with the same name as its Name property.
You can manually make changes to the SqlLoader.Columns collection to exclude some columns from INSERT statement generated by SqlLoader object.
