oracle 循环语句,该怎么解决

declare tag_hight number;        hight integer;        tag_body number;       bodytype number;begin     tag_hight:=1;     hight:=160;      while(tag_hight<4) loop   --exit when tag_hight>3;  tag_body:=1;  bodytype:=130;    while(tag_gbdy<4)      loop                        --exit  when tag_body>3;            insert into YU values(tag_hight,'XX','YYY',to_char(bodytype)||'/'||to_char(hight)||'b','0');             bodytype:=bodytype+2;             tag_body:=tag_body+1;       end loop          tag_hight:=tag_hight+1;        hight:=hight+5;          end loop; end;
