你已經錯過了line6分號。

v_amount all_sales.amount%TYPE; 

還有一個問題是group by子句。您需要將數據與員工名字和姓氏分組。像這樣嘗試，

SET SERVEROUTPUT ON 
DECLARE 
    v_employee_fname employees2.first_name%TYPE; 
    v_employee_lname employees2.last_name%TYPE; 
    v_amount all_sales.amount%TYPE; 

    CURSOR v_fullcount_cursor IS 
    SELECT e2.first_name, e2.last_name, sum(alls.amount) AS total_sales 
    FROM employees2 e2 JOIN all_sales alls ON e2.employee_id = alls.EMP_ID 
    GROUP BY e2.first_name, e2.last_name; 

    BEGIN 
      OPEN v_fullcount_cursor; 
      LOOP 
       FETCH v_fullcount_cursor 
       INTO v_employee_fname, v_employee_lname, v_amount; 
       EXIT WHEN v_fullcount_cursor%NOTFOUND; 
       DBMS_OUTPUT.PUT_LINE(v_employee_fname ||' '|| v_employee_lname ||' total sales are $'|| v_amount); 
      END LOOP; 
      CLOSE v_fullcount_cursor; 
    END;
