Patrick,

Since you seem to be the genius at joins, do you think this query can be shortened?

      SELECT c.email || '|' || ca.first_name || '|' || ca.last_name || '|' || 'ZACKS' || '|' ||
         TO_CHAR(c.date_registered, 'mmddrr hh24:mi:ss') || '|' || TO_CHAR(TRUNC(SYSDATE-1),'MM-DD-YYYY') || '|' ||

subscr_email_product s, customer_address cd
