am new to ORACLE; please help
Am trying to run a query which pulls up records based on dates;
if date is monday the query should run thrice; that is for monday, sunday, saturday (previous days also) for others days (tue to thursday only for same day);
First, if you want to run the query three times you'll need to do that in something other than plain SQL: PL-SQL, Java, C#, something.
However if you'd like Saturday and Sunday's figures to be included in Monday's you'll need to do something like a CASE statement to change the Sats & Suns to Mons.
case when (trim(to_char((date), 'Day', 'NLS_DATE_LANGUAGE=ENGLISH'))
in ('Saturday', 'Sunday', 'Monday')) then 'Monday'
else trim(to_char((date), 'Day', 'NLS_DATE_LANGUAGE=ENGLISH'))
end
Am trying to run a query which pulls up records based on dates
For scheduling based on calendering, Oracle provides DBMS_SCHEDULER.
For example, the below job would execute every hour:
SQL> BEGIN
2 DBMS_SCHEDULER.DROP_JOB (JOB_NAME => 'test_full_job_definition');
3 END;
4 /
PL/SQL procedure successfully completed.
SQL>
SQL> BEGIN
2 DBMS_SCHEDULER.create_job (
3 job_name => 'test_full_job_definition',
4 job_type => 'PLSQL_BLOCK',
5 job_action => 'BEGIN my_job_procedure; END;',
6 start_date => SYSTIMESTAMP,
7 repeat_interval => 'freq=hourly; byminute=0; bysecond=0;',
8 end_date => NULL,
9 enabled => TRUE,
10 comments => 'Job defined entirely by the CREATE JOB procedure.');
11 END;
12 /
PL/SQL procedure successfully completed.
SQL>
SQL> SELECT JOB_NAME, ENABLED FROM DBA_SCHEDULER_JOBS where job_name ='TEST_FULL_JOB_DEFINITION'
2 /
JOB_NAME ENABL
---------------------------------------- -----
TEST_FULL_JOB_DEFINITION TRUE
SQL>

I created a job which runs in my database successfully with DBMS_SCHEDULER ,but now I need to disable this job, how can i do this?
thanks!
Although the current answers provide a solution to how disable a job, I wanted to go a bit further and explain you how the job is created has an effect on whether the job needs to be disabled in the first place.
I am assuming you are using dbms_scheduler.
Job is created with auto_drop true and enabled true
In this case, once the job is created ( assuming you don't have any start time in the future ) the job executes immediately ( because it is enabled ) and then it is dropped automatically ( auto_drop is true )
SQL> begin
DBMS_SCHEDULER.create_job
(
job_name => 'MY_TEST',
job_type => 'PLSQL_BLOCK',
job_action => 'begin dbms_lock.sleep(5); end;',
enabled => TRUE ,
auto_drop => TRUE
);
end;
/ 2 3 4 5 6 7 8 9 10 11
PL/SQL procedure successfully completed.
SQL>
SQL> exec dbms_lock.sleep(5); -- waiting 5 seconds
PL/SQL procedure successfully completed.
SQL> select job_name,job_action from dba_scheduler_jobs where job_name = 'MY_TEST' ;
no rows selected
SQL>
Job is created with auto_drop to false and enabled to true
In this case, the job runs and it disables itself automatically. In this scenario you don't need to do anything to disable it.
SQL> begin
2 DBMS_SCHEDULER.create_job
3 (
4 job_name => 'MY_TEST',
5 job_type => 'PLSQL_BLOCK',
6 job_action => 'begin dbms_lock.sleep(5); end;',
7 enabled => TRUE ,
8 auto_drop => FALSE
9 );
10* end;
11 /
PL/SQL procedure successfully completed.
select job_name , state, enabled from dba_scheduler_jobs where job_name = 'MY_TEST' ;
JOB_NAME STATE ENABLE
----------------------------------
MY_TEST SUCCEEDED FALSE
Therefore, if your job is enabled is because it has a calendar frequency associated to it, so once has executed, it states enabled until the next time it has to execute
Job with frequency
It means that the job was created to executed based on an expression calendar. In this case, the job executes based on the calendar expression associated to it, and remains enabled and in state SCHEDULED.
SQL> exec dbms_scheduler.drop_job ( job_name => 'MY_TEST' ) ;
PL/SQL procedure successfully completed.
SQL> begin
DBMS_SCHEDULER.create_job
(job_name => 'MY_TEST',
job_type => 'PLSQL_BLOCK',
job_action => 'begin dbms_lock.sleep(5); end;',
enabled => TRUE ,
start_date => systimestamp ,
repeat_interval => 'FREQ=DAILY;BYDAY=MON,TUE,WED,THU,FRI;'
);
end;
/
PL/SQL procedure successfully completed.
SQL> select job_name , state, enabled from dba_scheduler_jobs where job_name = 'MY_TEST' ;
JOB_NAME STATE ENABLE
--------------------------------------
MY_TEST SCHEDULED TRUE
In this case, as it was point out in the other answers:
SQL> exec dbms_scheduler.disable ( 'MY_TEST' ) ;
PL/SQL procedure successfully completed.
SQL> select enabled from dba_scheduler_jobs where job_name = 'MY_TEST' ;
ENABL
-----
FALSE
Summary
If you want to run a job just once and eliminate it, use the option 1 ( auto_drop and enabled )
If you want to run a job and leave it there for run it on demand whenever you want, but disabled. Use option 2 ( auto_drop to false and enabled to true )
Normally you disable jobs that are created with frequency and execute based on some kind of calendar expression.
Obviously, that is just a set of small examples of the many options you have available with dbms_scheduler
Oracle has a good package for schedule jobs.
In your case , you need disable procedure.
Here is the detailed information about dbms_scheduler
Simply call this using oracle new query window like this and your job will be disabled:
begin dbms_scheduler.disable('job-name'); end;
Or in command window :
exec dbms_scheduler.disable('SCHEMA_MNTC_JOB');
You can create a PL/SQL Procedure that disable your job, with the name in parameter
BEGIN
DBMS_SCHEDULER.DISABLE('name_of_your_job');
END;
/
Execute it
EXEC dbms_scheduler.disable('name_of_your_job');
I hope this will solve your problem
I have created a oracle dbms scheduler to execute a procedure daily at 05 AM, 10 AM, 03 PM and 08 PM. Below is the scheduler code
DBMS_SCHEDULER.CREATE_JOB
(
job_name => 'TEST_JOB'
,start_date => SYSDATE
,repeat_interval => 'FREQ=DAILY; BYHOUR=05,10,15,20; BYMINUTE=00 ;BYSECOND=0;'
,end_date => NULL
,job_class => 'DEFAULT_JOB_CLASS'
,job_type => 'PLSQL_BLOCK'
,enabled => TRUE
,job_action => 'BEGIN INSERT_IN_TABLE; END;'
,comments => 'TEST JOB'
);
now i have to modify the same scheduler to execute the same procedure only twice on weekends and run at same frequency on weekdays.
I don't want to create a different scheduler for the weekend executions because sometimes the procedure takes more than 5 hours to execute.
Please guide me if there is a better way to achieve this.
One option could be to use embedded calendars, so that you can create your own calendar expression.
Let me show you an example
SQL> BEGIN
dbms_scheduler.create_schedule('my_schedule_c_1', repeat_interval =>
'FREQ=DAILY; BYHOUR=05,10,15,20; BYMINUTE=00; BYSECOND=00; ');
dbms_scheduler.create_schedule('my_schedule_c_2', repeat_interval =>
'FREQ=DAILY; BYDAY=SAT,SUN; BYHOUR=05,10; BYMINUTE=00; BYSECOND=00;');
END;
/ 2 3 4 5 6 7
PL/SQL procedure successfully completed.
SQL> begin
DBMS_SCHEDULER.create_schedule ('MY_CALC', repeat_interval =>'my_schedule_c_1, my_schedule_c_2');
END;
/ 2 3 4
PL/SQL procedure successfully completed.
SQL>
Then , you only need to apply this schedule to your job
SQL> begin
2 DBMS_SCHEDULER.CREATE_JOB
(
job_name => 'TEST_JOB'
,start_date => SYSDATE
3 ,repeat_interval => 'MY_CALC'
4 ,end_date => NULL
,job_class => 'DEFAULT_JOB_CLASS'
,job_type => 'PLSQL_BLOCK'
5 6 7 8 9 10 ,enabled => TRUE
,job_action => 'BEGIN NULL; END;'
,comments => 'TEST JOB'
); 11 12 13
14 end;
15 /
PL/SQL procedure successfully completed.

This way, my job will run using the MAIN_CALC schedule, which is a combination of the two different frequencies.
Of course, you can always create two jobs, but in 11g there is no option to create incompatibilities, which is an object in DBMS_SCHEDULER 12c onwards that prevents a job to start until the other is completed.
My advice, use a schedule calendar embedded with multiple frequencies
I have table with TIMESTAMP type column.
I have procedure which inserts into this table:
CREATE OR REPLACE PROCEDURE my_procedure
AS
BEGIN
INSERT INTO t2
(dt)
VALUES
(LOCALTIMESTAMP);
END;
Then create schedule:
BEGIN
dbms_scheduler.create_job(
job_name => 'my_job',
job_type => 'stored_procedure',
job_action => 'my_procedure',
start_date => '2016-10-31 17:01:01',
repeat_interval => 'FREQ=SECONDLY;INTERVAL=10',
end_date => '2016-11-30 17:01:01',
auto_drop => FALSE
);
END;
EXEC dbms_scheduler.ENABLE('my_job');
Then SELECT * FROM t2 ORDER BY dt
Results are:
2016-10-31 17:40:13
2016-10-31 17:40:21
2016-10-31 17:40:34
2016-10-31 17:40:42
2016-10-31 17:40:54
As you see, INTERVAL for schedule is 10 second, but difference between inserts (rows) are sometimes 8 second, sometimes 13 second, sometimes 12 second and so on.
Question: why is so not exactly that interval between procedure calls, which is defined in schedule?
Trying to create job But can't compile it keeps me given this error. There is a question on oracle forums, it say's that i have to create program to wrap it. Is there any workaround for this?

After i created job from PL/SQL Developer UI, i found out my syntax erorrs, new code is below;
i use sys.dbms_scheduler.create_job instead of dbms_scheduler.create_job. I don't know differances but it's not important alteration.
i used to_date to define start_date, as a fresh-starter i found this better practise.
Important I added job_class parameter to 'DBMS_JOB$'. DBMS_JOB is built_in job class of Oracle RDBMS. So you find all jobs with this query:
select * from ALL_SCHEDULER_JOBS WHERE JOB_CLASS='DBMS_JOB$'
Important My interval's were wrong you should put ; between all parameters like
repeat_interval => freq=weekly;byhour=10, 13
My first job code has another syntax error i use enable instead of enabled.
I set auto_drop false. I guess this parameter is used to drop job when it dones his job. I mean if you create a job that makes changes daily from today to next week. After end-time reaches, this job has dropped. Please correct me if i wrong.
sys.dbms_scheduler.create_job(job_name => 'BOMBASTICJOB'
,job_type => 'STORED_PROCEDURE'
,job_action => 'dingdongprocedure'
,start_date => to_date('30-09-2014 00:00:00'
, 'dd-mm-yyyy hh24:mi:ss')
,end_date => to_date(null)
,job_class => 'DBMS_JOB$'
,repeat_interval => 'Freq=Weekly; ByDay=Tue, Fri; ByHour=10, 13'
,enabled => true
,auto_drop => false
,comments => '');
I am on 12.1.0.1.0. You could create the job in a simple anonymous block :

2 DBMS_SCHEDULER.DROP_JOB (JOB_NAME => 'test_full_job_definition');

Hi I have a stored procedure in oracle that I would like to run periodically. Firstly I got my DBMS_SCHEDULER Job to compile (see below) and I can even see the job be created and drop it though I don't see the result of the stored procedure occur in the table it is supposed to effect and the stored procedure has been tested.
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'JOB_QUERY',
job_type => 'PLSQL_BLOCK', -- see oracle documentation on types --
job_action => 'BEGIN RUNREPORT(''NAME'', ''VERSION'', ''04-Jun-13'', ''11-Jun-13''); END;',
start_date => to_date('2013-08-19 16:35:00', 'YYYY-MM-DD HH24:MI:SS' ),
repeat_interval => 'FREQ=MINUTELY;BYMINUTE=10', -- every 10 minutes.
end_date => NULL,
enabled => TRUE,
comments => 'Daily Jira Query Update');
END;
I was attempting to simply make it run every ten minutes though I see no changes. Also I wanted to be able to pass SYSDATE or the current date to the procedure in the dbms_scheduler job but I cant get it to work with the apostrophes.
Thanks
You have to COMMIT your DML statements. There is no COMMIT in PL/SQL block and I guess in procedure RUNREPORT either.
You don't need an apostrophe around sysdate, it's not a string literal.
job_action => 'BEGIN RUNREPORT(''NAME'', ''VERSION'', sysdate, ''11-Jun-13''); COMMIT; END;',
BYMINUTE does not mean what you would expect. From documentation:
"This specifies the minute on which the job is to run. Valid values are 0 to 59. As an example, 45 means 45 minutes past the chosen hour". What you need is
repeat_interval => 'FREQ=MINUTELY;INTERVAL=10'
You can check next run date and more by querying user_scheduler_jobs.
If you are calling the stored procedure from DMBS Scheduled job you can try below.
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
JOB_NAME => 'SCHEMA.MY_DBMS_SCHEDULED_JOB',
JOB_TYPE => 'STORED_PROCEDURE',
JOB_ACTION => 'SCHEMA.STORED_PROCEDURE_TO_BE_CALLED',
START_DATE => '01-AUG-13 12.00.00 AM',
REPEAT_INTERVAL => 'FREQ=DAILY;BYHOUR=0;BYMINUTE=10',
AUTO_DROP => FALSE,
ENABLED => TRUE,
NUMBER_OF_ARGUMENTS => 0,
COMMENTS => 'Scheduled job to perform updates.');
END;
/
To see if your scheduler log you can use below query.
SELECT * FROM all_SCHEDULER_JOB_LOG
where job_name='MY_DBMS_SCHEDULED_JOB'
order by log_id desc;
