为Oracle dbms_scheduler作业存储过程设置命名参数

Question

是否可以将类型为'stored_procedure'的命名参数传递给dbms_scheduler作业？我已经尝试过这种方式：

-- 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;  

我收到以下错误：ORA

-27484：没有程序的作业不支持参数名称。 ORA-06512：在“ SYS.DBMS_ISCHED”行207上ORA-06512：在“ SYS.DBMS_SCHEDULER”，第602行ORA-06512：第2行

我通过使用arguments_position设置成功使用set_job_argument_value设置了参数值。但是在某些情况下，我需要运行存储过程，而我只需要为其设置某些参数，而这是行不通的。有没有一种方法可以将命名参数传递给调度程序作业运行的存储过程？

Answer 1

作为错误状态，请先创建一个程序，然后在其上创建作业。

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

我有一个基本的程序示例

1.-创建我的步骤

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.-创建程序

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.-创建工作

BEGIN
    DBMS_SCHEDULER.CREATE_JOB (
        job_name => '"XXFLM"."MY_TEST_JOB"',
        PROGRAM_NAME => 'MY_TEST_PROGRAM'
    );

END;

4.- PL / SQL代码测试

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.-结果

SELECT * FROM ALL_SCHEDULER_JOB_RUN_DETAILS ORDER BY 1 DESC;
