Cherie,

Change the clause as follows

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

new ==> erh.arrival_dt <= sysdate - 7 AND

Hope this helps!

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,
