about when is the last time some particular account accessed the database? This trigger will update the database keeping statistics on who logs on to the database and how many times per month. I have it installed and have it running successfully on Oracle 22.214.171.124.0 and Oracle 9.2.0.
One note I would like to add is that I removed the schema name from the table name in the trigger script. To make it work smoothly, anyone wanting to use this procedure should create a public synonym for the table as follows:
create public synonym user_logins for
First, create a table to hold the stats:
create table user_logins ( userid varchar(30), logon_month number, logon_cnt number );
declare curr_month number(6); cnt_month number(8); begin select to_char(sysdate,'YYYYMM') into curr_month from dual; select count(*) into cnt_month from user_logins where userid = user and logon_month = curr_month; if cnt_month = 0 then insert into user_logins values (user, curr_month, 1); else update user_logins set logon_cnt = logon_cnt + 1 where userid = user and logon_month = curr_month; end if; end; /
