    Description:
    I need to

    select Z308_REC_KEY from z308 where Z308_REC_KEY like ‘07%’;

    but only for those patrons that do have at least one loan between jan 12,2012 and April 30,2012

    Resolution:
    I believe that this will give you what you want:

    SQL> select unique z35_id from z35 where z35_event_type like '5%' and z35_event_date > '20120111' and z35_event_date < '20120431' and z35_id in (select z308_id from usr00.z308 where z308_rec_key like '07%');

    (you will need to change the "usr00" to your $usr_library -- unless it's your ADM library, in which case you can omit it).
