loop与for loop分别实现乘法口诀表

set serveroutput on;declare  i number(4,0):=1;  j number(4,0);begin  loop    exit when i = 10;    j:=1;      loop               exit when j = i+1;        dbms_output.put(i||'*'||j||'='||i*j||' ');        j:=j+1;      end loop;          i:=i+1;         dbms_output.put_line(null);  end loop;end;

set serveroutput on;declare m number(2,0);begin for i in 1..9 loop for j in 1..i loop m:=i*j; dbms_output.put(i||'*'||j||'='||m||' '); end loop; dbms_output.put_line(null); end loop;end;
