Hello,
Today we faced below error when quering dba_jobs:
SQL> select * from dba_jobs where job=4474623; select * from dba_jobs where job=4474623 ORA-01873: the leading precision of the interval is too small SQL>Oracle database is on 19c version so this dbms_job automatically converted in scheduler so this way it is correctly working:
select * from dba_scheduler_jobs where job_name='DBMS_JOB$_4474623';so problem is dba_jobs view, we can see how it looks like :
create or replace view dba_jobs as
select
m.dbms_job_number JOB, j.creator LOG_USER, u.name PRIV_USER,
u.name SCHEMA_USER,
CAST(j.last_start_date AS DATE) LAST_DATE,

So there is important comment on total time that -- Scheduler does not track total time.Solution :
we can change dba_jobs view with this query to solve this problem or you can query from dba_Scheduler_jobs, we are changing just total_time field calculation with this:
( CASE
WHEN j.last_end_date > j.last_start_date THEN
--EXTRACT (
--DAY FROM (j.last_end_date - j.last_start_date) * 86400)
(CAST(j.last_end_date AS DATE)-CAST(j.last_start_date AS DATE)) * 86400
ELSE
0
END )
TOTAL_TIME, -- Scheduler does not track total time
So whole view will be like that :
create or replace view dba_jobs as
select
m.dbms_job_number JOB, j.creator LOG_USER, u.name PRIV_USER,
u.name SCHEMA_USER,
CAST(j.last_start_date AS DATE) LAST_DATE,
substr(to_char(j.last_start_date,'HH24:MI:SS'),1,8) LAST_SEC,
CAST(
DECODE(BITAND(j.job_status,2), 2, j.last_start_date, NULL)
AS DATE) THIS_DATE,
DECODE(BITAND(j.job_status,2), 2,
substr(to_char(j.last_start_date,'HH24:MI:SS'),1,8), NULL) THIS_SEC,
CAST(j.next_run_date AS DATE) NEXT_DATE,
substr(to_char(j.next_run_date,'HH24:MI:SS'),1,8) NEXT_SEC,
( CASE
WHEN j.last_end_date > j.last_start_date THEN
--EXTRACT (
--DAY FROM (j.last_end_date - j.last_start_date) * 86400)
(CAST(j.last_end_date AS DATE)-CAST(j.last_start_date AS DATE)) * 86400
ELSE
0
END )
TOTAL_TIME, -- Scheduler does not track total time
DECODE(BITAND(j.job_status,1),0,'Y','N') BROKEN,
DECODE(BITAND(j.flags,1024+4096+134217728),
0, j.schedule_expr, NULL) INTERVAL,

j.nls_env NLS_ENV, j.env MISC_ENV, NVL(j.instance_id, 0) INSTANCE

left outer join sys.obj$ o on (o.name = m.job_name)

after change dba_jobs view we can query that job without any error:
SQL> select * from dba_jobs where job=4474623;
