PLS-00306：调用 'GET_LINE' 时参数的数量或类型错误。在 PL/SQL 中的函数中传递字符串参数时出现此错误

Question

这是我的函数，它采用 department.dept_name%type 类型的参数。这是 varchar2(20)

```
create or replace function count_doc(dep_name_local department.dept_name%TYPE)
return number is
x int;
begin
select count(doc_id) into x from doctor where dept_no in(select dept_no  from department where dept_name=dep_name_local); 
return x;
end;

 ```

这是我的函数调用。

    declare
    dep_namePass department.dept_name%TYPE;
    
    begin
    dep_namePass:='Cardiology';
    dbms_output.get_line(count_doc(dep_namePass));
    end;

     ```
Please tell me what am I doing wrong. I am a beginner :( . I am doing this in livesql btw.

是dbms_output.put_line，不是get_line。
