SQL script, how can i execute the following script?

Question

I have to execute this script . The problem in that in SQL Developer i cant run it,since some operators are not recognized .

P_jobgroup_id :
'GDWH2MYGDWH-GDWH2MYGDWH'           CORE load finished
'GDWH2MYGDWH-GDWH2MYGDWH_IF'        IF finished
'GDWH2MYGDWH-GDWH2MYGDWH_INIT'  IF or CORE started

declare
 p_context_code          varchar2(100) := 'GDWH2MYGDWH';
 v_res                   varchar2(100);
begin
v_res := OJC.jc_master.main 
     (
      p_batch_number => NULL,
      p_jobgroup_id => 'GDWH2MYGDWH-GDWH2MYGDWH'),
      p_parameters_string => 'GDWH2MYGDWH.PRM_REPORTING_DATE='||to_char(sysdate,'yyyymmddhh24miss',
      p_context_code =>p_context_code
     );
end;

Answer 1

The first par of the script is not valid PLSQL code. Commenting or removing it will make the script run, once fixed a couple of syntax errors.

/*

    'GDWH2MYGDWH-GDWH2MYGDWH'           CORE load finished
    'GDWH2MYGDWH-GDWH2MYGDWH_IF'        IF finished
    'GDWH2MYGDWH-GDWH2MYGDWH_INIT'  IF or CORE started

DECLARE

    v_res                                   VARCHAR2(100);

        );
END;
