ora-01036 非法的变量名/编号???????测试不通过
我刚学习PL/SQL Developer,试写了个存储过程如下:
create or replace procedure pp(in_num number,out_num out number) astotal1 number:=0;total2 number:=0;begin select sum(s.totalmoney) into total1 from salerecord s where s.customerid = in_num; select sum(s.totalmoney) into total2 from salerecord s; out_num := round((total1/total2*100),2); dbms_output.put_line('地区编号为'||in_num||'的地区的销售额占总销售的百分之：'||out_num);end;declaret_t number;begin -- Call the procedure pp(2,t_t); dbms_output.put_line(t_t);end;
