如何执行oracle的存储过程？

zsmdev

存储过程保存在precedure.sql文件中，如下：
set echo on
set serveroutput on

declare
   emp_name_c char(32);
   emp_name_v varchar2(32);
begin
   emp_name_c:='Jenny Gennick';
  emp_name_v:='Jenny Gennick';
  
  if trim(emp_name_c)=emp_name_v then
     dbms_output.put_line('The names are the same');
  else
    dbms_output.put_line('The names are NOT the same');
end if;
end;
/


declare
   emp_name_c char(32);
   emp_name_v varchar2(32);
begin
   emp_name_c:='Jenny Gennick';
  emp_name_v:='Jenny Gennick';
  
  if trim(emp_name_c)=emp_name_v then
     dbms_output.put_line('The names are the same');
  else
    dbms_output.put_line('The names are NOT the same');
end if;
end;
/



declare
   emp_name_c char(32);
   emp_name_v varchar2(32);
begin
   emp_name_c:='Jenny Gennick';
  emp_name_v:='Jenny Gennick';
  
  if trim(emp_name_c)=emp_name_v then
     dbms_output.put_line('The names are the same');
  else
    dbms_output.put_line('The names are NOT the same');
end if;
end;
/

exit;
