在期待以下之一时遇到符号"IS"

Question

我一直在尝试运行这个脚本,但我得到的只是这个错误:

Error report:
ORA-06550: line 3, column 15:

PLS-00103: Encountered the symbol "IS" when expecting one of the following:

constant exception <an identifier>
<a double-quoted delimited-identifier> table long double ref
char time timestamp interval date binary national character
nchar
The symbol "IS" was ignored.

这是我的脚本:

set serveroutput on

   DECLARE
   cursor depts_cur is select dname from dept;
   depts_cur_rec is depts_cur%type; 

   BEGIN
   loop
     fetch depts_cur into depts_cur_rec;
     exit when depts_cur_rec%notfound;
     dbms_output.put_line('Department: ' || depts_cur_rec);
   end loop;
   close depts_cur;
   END;

非常感谢您的帮助.

看起来你的depts_cur_rec声明是错误的,试试这个(删除"是"):

set serveroutput on

DECLARE
    cursor depts_cur is select dname from dept;
    depts_cur_rec depts_cur%type;
BEGIN
    BEGIN loop 
        fetch depts_cur 
        into depts_cur_rec; 
        exit when depts_cur_rec%notfound;
        dbms_output.put_line('Department: ' || depts_cur_rec); 
    end loop;
    close depts_cur;
END;
