Thanks Paul
Correct syntax to use with cursors:
declare
emp_name employees.last_name%type;
emp_job employees.job_id%type;
cursor c1 is
select last_name,job_id from employees
where job_id like ‘%CLERK%’ and manager_id>120;
BEGIN
for a1 in c1 loop
dbms_output.put_line(‘Name = ‘ ||a1.last_name||’, Job= ‘||a1.job_id);
end loop;
END;
/
Correct answer D.
You can execute following statement, it gives error:
HR@XE > declare
2 emp_name employees.last_name%type;
3 emp_job employees.job_id%type;
4 cursor c1 is
5 select last_name,job_id from employees
6 where job_id like ‘%CLERK%’ and manager_id>120;
7 BEGIN
8 for emp_name,emp_job in c1 loop
9 dbms_output.put_line(‘Name = ‘ ||emp_name||’, Job= ‘||emp_job);
10 end loop;
11 END;
