Oracle Error Message
SQL*Loader-00472: collections can contain only one non FILLER field specification
Reason for the Error
More than one non filler field specification is found in a collection field’s member field list.
Solution
See correct syntax in the Utilities Manual. If indeed there is more than one attribute that makes up the particular collection, then it must be a collection of a object type which needs to be specified using the COLUMN OBJECT field specification syntax.
