Hi All, I need find data, which are meet criteria 10 minutes before and 10 minutes after specific time. This is what I have and it?s not working properly with between function: select id_number from test where status = 'X' and id_number in (select id_number from test where to_date(to_char (changed_on,'MM/DD/YYYY HH24:MI'),'MM/DD/YYYY HH24:MI') in select to_char (audit_timestamp,'MM/DD/YYYY HH24:MI') from result_table where to_date(to_char (audit_timestamp,'MM/DD/YYYY HH24:MI'),'MM/DD/YYYY HH24:MI') between to_date(to_char (audit_timestamp - 1/288,'MM/DD/YYYY HH24:MI'),'MM/DD/YYYY HH24:MI') and to_date(to_char (audit_timestamp + 1/288,'MM/DD/YYYY HH24:MI'),'MM/DD/YYYY HH24:MI'); Thanks. --------------------------------- Yahoo!
