Try this, it selects the one who connect in half an hour ...
but you can use a dynamic sql instead if this works via cron and write the
where clause by taking
from system date and time..
select sysdate, sysdate - 1./48. , s.logon_time from v$session s
where logon_time > sysdate - 1./48.
SYSDATE SYSDATE-1./48. LOGON_TIME

Hi lists
i need help in writing a sql query:
i am trying to capture the session information from v$session and
inserting the same into someother table xyz with columns username,
logon_time. (scott logged in at 10:30 hrs)
i put this script in cron. it runs every 30 minutes. but i need the
values shoudld not be duplicated.
Every time the shell script runs, it inserts values into XYZ. table.
Here i need your help. The values should not be duplicated that are
being insreted into xyz.
since username,logon_time are composite primary key, system will not
accept duplicates.
Because, in the v$session, if the user stays more than 30 minutes, his
values will be sent to xyz table and as already xyz has that row
(inserted before 30 minutes by shell), system will deny to insert the
duplicate the value into xyz.
any scripts? scripts?
thanx in advance
srinivas
