I think that the following statement is keeping this application from using
an index in my cost-based execution plan.  This is an 8.0.4 database so I
don't have the option of creating a function-based index.

I'm not that great with SQL.  Can anyone help me rewrite this statement so
that I don't need to use the TRUNC function on this column in blue?

  (trunc(sysdate) - trunc(erh.arrival_dt)) >= 7 AND

Thanks,
