Answer 1

您错过了程序声明的结尾

END PrintTimeTable_Procedure：

并且您不能在pl / sql过程中使用PROMPT。它需要更像

Create or replace your procedure....  as
Begin
....
End;
/
BEGIN
PrintTimeTable_Procedure;
END;

从SQLPlus或IDE中运行它是不是很清楚？

Answer 2

您错过了程序的END，并且您没有为记录字段使用正确的名称。您不需要在字段名称中包含表别名（即aRow.Cu.FIRST_NAME错误，该字段名为FIRST_NAME，aRow.FIRST_NAME）。此外，我无法看到任何名为EMPLOYEE_ID

的字段

CREATE OR REPLACE PROCEDURE PrintTimeTable_Procedure (T_Customer_id NUMBER DEFAULT NULL) AS
BEGIN
  FOR aRow IN (SELECT Cu.Customer_id,
                      Cu.First_Name,
                      CT.CUSTOMER_T_ID,
                      CT.C_DATE,
                      CT.TIMETABLE_ID,
                      CT.CUSTOMER_ID,
                      T.TIMETABLE_ID,   
                      T.CLASS_DAY, 
                      T.CLASS_LOCATION,
                      T.CLASS_START_TIME, 
                      T.CLASS_FINISH_TIME,
               FROM Customers Cu, customer_timetable CT, TimeTable T
               WHERE C.Customer_id = CT.CUSTOMER_ID 
               AND CT.TIMETABLE_ID = T.TIMETABLE_ID
               AND CT.Customer_id = T_Customer_id) LOOP
    DBMS_OUTPUT.PUT_LINE('Customer ID: ' || aRow.CUSTOMER_ID);
    DBMS_OUTPUT.PUT_LINE('NAME: ' || aRow.FIRST_NAME);
    DBMS_OUTPUT.PUT_LINE('DATE: ' || aRow.C_DATE);
    DBMS_OUTPUT.PUT_LINE('DAY: ' || aRow.Class_Day);
    DBMS_OUTPUT.PUT_LINE('CLASS LOCATION: ' || aRow.CLASS_LOCATION);
    DBMS_OUTPUT.PUT_LINE('START TIME: ' || aRow.CLASS_START_TIME);
    DBMS_OUTPUT.PUT_LINE('FINISH TIME: ' || aRow.CLASS_FINISH_TIME);
  END LOOP;
END;

PROMPT PrintTimeTable_Procedure Procedure
BEGIN
  PrintTimeTable_Procedure;
END;
