How to create scheduled tasks in PL/SQL?

In PL/SQL, you can use the DBMS_SCHEDULER package to create scheduled tasks. For example, to create a scheduled task, follow these steps: 1. Log in to the Oracle database using the SYS user or a user with appropriate permissions. 2. In SQL*Plus or a similar tool, enter the command to create a job.

BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
    job_name => 'my_job',
    job_type => 'PLSQL_BLOCK',
    job_action => 'BEGIN my_procedure(); END;',
    start_date => SYSTIMESTAMP,
    repeat_interval => 'FREQ=DAILY; BYHOUR=12;',
    enabled => TRUE,
    comments => 'My job');
END;
/

In the example above, a job named “my_job” is created. The job is of type PL/SQL_BLOCK, which executes an anonymous PL/SQL block that calls a stored procedure named “my_procedure”. Set the job’s repeat interval and enable status. In the example above, the job is set to run every day at noon (FREQ=DAILY; BYHOUR=12;), and the job is enabled (enabled => TRUE). Submit the command to create the job. Once the above steps are completed, the scheduled task will automatically run at the specified time interval. You can modify or delete the created scheduled tasks as needed.
