You can modify the following query to return a count. -dave.clark -------------------------------------------- The following select formats information from the system view DBC.LogOnOff and DBC.EventLog into a single line output for each session. The select returns sessions logged on at any time during the specified interval. If the beginning and the end of the interval are equal, only sessions logged on at that instant will be returned. Note that some of the sessions returned may have logged on earlier than the beginning of the interval and may have logged off after the end of the interval. This select does not find session that have not yet logged off. This is because it looks for sessions with both a logon and logoff event. Sessions still logged on will not have a logoff event in DBC.EventLog. Here is some sample output (NOTE: this tends to generate a lot of output) User Session Host IFP Logon Logoff -------- ------- ---- ------ -------- -------- STV2 1260 52 16383 98/10/05 13:26:06.94 99/12/31 23:58:15.44 DBC 1500 52 16383 98/10/05 15:05:49.57 99/12/31 23:58:15.52 STV2 1740 52 16383 98/10/05 15:09:36.41 99/12/31 23:58:15.44 ------------------------------------------------------------- sel a.Username(title'User')(format'x(12)') ,a.SessionNo(title'Session')(format'zzzzzz9') ,a.LogicalHostID(title'Host') ,a.IFPNo(title'IFP') ,a.LogDate(title'Logon') ,a.LogTime(title' ') ,cast(b.LogDate as char(8))(title'Logoff') ,cast(b.LogTime as char(12))(title' ') from DBC.LogOnOff a, DBC.LogOnOff b where a.Event='Logon' and b.Event<>'Logon' and a.SessionNo=b.SessionNo and a.IFPNo=b.IFPNo and a.LogonDate=b.LogonDate and a.LogonTime=b.LogonTime /* >>>>>>>>>>>>>>>>>> ending date and time */ and ((a.LogDate= DATE and a.LogTime<= TIME) or a.LogDate< DATE) /* >>>>>>>>>>>>>>>>>> beginning date and time */ and ((b.LogDate= DATE-1 and b.LogTime>= 120000) or b.LogDate> DATE-1) union sel UserName(title'User')(format'x(12)') ,SessionNo(title'Session')(format'zzzzzz9') ,LogicalHostID mod 1024 (title'Host') ,IFPNo(title'IFP') ,LogonDate(title'Logon') ,LogonTime(title' ') ,' Logged'(title'Logoff') ,'On '(title' ') from DBC.SessionInfo /* >>>>>>>>>>>>>>>>>> ending date and time */ where (LogonDate = DATE and LogonTime <= TIME) or LogonDate < DATE order by 5,6,2;
