Set named parameter for Oracle dbms_scheduler job stored procedure - stored-procedures

Question

Is it possible to passed named arguments to for dbms_scheduler job with a type 'stored_procedure' ? I've tried this way:
-- 1) example dummy procdure
CREATE OR REPLACE PROCEDURE my_test_proc (
param1 IN NVARCHAR2,
param2 IN NUMBER,
param3 IN NUMBER
) IS
BEGIN
-- ...
END;
-- 2)Example dummy job:
BEGIN
dbms_scheduler.create_job(
job_name => 'my_test_job'
,job_type => 'STORED_PROCEDURE'
,job_action => 'my_test_proc'
,start_date => sysdate
,number_of_arguments => 3
,enabled => FALSE
,auto_drop =>FALSE
);
END;
-- 3)Set named param value:
BEGIN
dbms_scheduler.set_job_argument_value(
job_name => 'my_test_job'
,argument_name => 'param1'
,argument_value => 'some value'
);
END;
I get following error:
ORA
-27484: Argument names are not supported for jobs without a program. ORA-06512: at "SYS.DBMS_ISCHED", line 207 ORA-06512: at
"SYS.DBMS_SCHEDULER", line 602 ORA-06512: at line 2
I successfully set parameter values with set_job_argument_value by using argument_position setting. But there can be cases when I will need to run stored procedures to whom I will need to set only certain parameters and this could not work. Is there a way to pass named argument to stored procedure runed by scheduler job?

Answer 1

as the error states, create a program first, then the job on that.
dbms_scheduler.create_program(program_name => 'YOUR_PROGRAM',
program_type => 'STORED_PROCEDURE',
program_action => 'my_test_proc',
number_of_arguments => 2,
enabled => false,
comments => 'Comments you want');
dbms_scheduler.define_program_argument(program_name => 'YOUR_PROGRAM',
argument_name => 'param1',
argument_position => 1,
argument_type => 'VARCHAR2',
default_value => '');
..etc, do for all 3.
dbms_scheduler.enable (name => 'YOUR_PROGRAM');
dbms_scheduler.create_job(job_name => 'my_test_job',
program_name => 'YOUR_PROGRAM',
start_date => systimestamp,
end_date => null,
...
dbms_scheduler.set_job_argument_value(job_name => 'my_test_job',
argument_position => 1,
argument_value => 'value');
...

Answer 2

I have a basic example for procedure
1.- CREATE MY PROCEDURE
CREATE OR REPLACE PROCEDURE MY_TEST_PROCEDURE (P_VAR1 VARCHAR2, P_VAR_NUMBER NUMBER)
AS
V_RESULT_MSG VARCHAR2(300);
BEGIN
DBMS_OUTPUT.PUT_LINE(TO_CHAR(SYSDATE,'DD/MM/YYYY HH24:MI'));
V_RESULT_MSG := P_VAR1;
V_RESULT_MSG := V_RESULT_MSG||' '||P_VAR_NUMBER;
DBMS_OUTPUT.PUT_LINE(TO_CHAR(SYSDATE,'DD/MM/YYYY HH24:MI'));
DBMS_OUTPUT.PUT_LINE(V_RESULT_MSG);
END MY_TEST_PROCEDURE;
2.- CREATE PROGRAM
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM(
PROGRAM_NAME => 'MY_TEST_PROGRAM'
,PROGRAM_TYPE => 'STORED_PROCEDURE'
,PROGRAM_ACTION => 'MY_TEST_PROCEDURE'
,NUMBER_OF_ARGUMENTS => 2
,ENABLED => FALSE
,COMMENTS => 'my test program'
);
DBMS_SCHEDULER.DEFINE_PROGRAM_ARGUMENT(
PROGRAM_NAME => 'MY_TEST_PROGRAM',
argument_name => 'P_VAR1',
argument_position => 1,
argument_type => 'VARCHAR2',
default_value => ''
);
DBMS_SCHEDULER.DEFINE_PROGRAM_ARGUMENT(
PROGRAM_NAME => 'MY_TEST_PROGRAM',
argument_name => 'P_VAR_NUMBER',
argument_position => 2,
argument_type => 'NUMBER',
default_value => ''
);
dbms_scheduler.enable (name => 'MY_TEST_PROGRAM');
END;
3.- CREATE JOB
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => '"XXFLM"."MY_TEST_JOB"',
PROGRAM_NAME => 'MY_TEST_PROGRAM'
);
END;
4.- PL/SQL CODE TEST
DECLARE
V_VAR1 VARCHAR2(50) := 'HOLA';
V_VAR2 NUMBER := 2010;
BEGIN
dbms_scheduler.set_job_argument_value(
job_name => 'MY_TEST_JOB',
argument_position => 1,
argument_value => V_VAR1);
dbms_scheduler.set_job_argument_value(
job_name => 'MY_TEST_JOB',
argument_position => 2,
argument_value => V_VAR2);
DBMS_SCHEDULER.RUN_JOB(
JOB_NAME => '"XXFLM"."MY_TEST_JOB"',
USE_CURRENT_SESSION => FALSE);
END;
5.- RESULT
SELECT * FROM ALL_SCHEDULER_JOB_RUN_DETAILS ORDER BY 1 DESC;
