As I recall, it took me a long time to realize that too. It may help to realize that everything you type between double-quotes (those SQL expressions) are made part of the INSERT statement SQL*Loader uses to insert each row. By the time that INSERT gets executed, SQL*Loader has to have parsed the input record and isolated all the fields. Thus, in a SQL expression, you have access to all the fields all the time. Related to the above, before Oracle9i, using SQL expressions with SQL*Loader precludes doing a direct-path load. 9i relaxed that restriction somewhat. It's been awhile though, since I've looked at exactly what 9i allows. You can see your SQL expressions in the INSERT statement. Just enable SQL tracing while you run one of your loads.
