Question

这是我的pl / sql块

declare 
b_emp_no employees.emp_no%type;
cursor c_employees is 
select emp_no from employees;
begin
open c_employees;
loop
fetch c_employees  into b_emp_no;
exit when c_employees%notfound;
end loop;
case b_emp_no
when b_emp_no=1 then
dbms_output.put_line('employee number is 1');
when b_emp_no=2 then
dbms_output.put_line('employee number is 2');
when b_emp_no=3then
dbms_output.put_line('employee number is 3');
when b_emp_no=4 then
dbms_output.put_line('employee number is 4');
when b_emp_no=5 then
dbms_output.put_line('employee number is 5');
when b_emp_no=6 then
dbms_output.put_line('employee number is 6');
when b_emp_no=7 then
dbms_output.put_line('employee number is 7');
when b_emp_no=8 then
dbms_output.put_line('employee number is 8');
when b_emp_no=9 then
dbms_output.put_line('employee number is 9');
when b_emp_no=10 then
dbms_output.put_line('employee number is 10');
when b_emp_no=11 then
dbms_output.put_line('employee number is 11');
else 
dbms_output.put_line('employees numbers:'||b_emp_no);
close c_employees;
end;
