这是我的 SQL Server 存储过程，如下所示：

CREATE PROCEDURE passenger_details
AS
BEGIN
SELECT Full_Name, Age, Nationality, Category, Airline_Name, Class_Type
FROM Passenger, Ticket, Airline, Class
WHERE Passenger.Passenger_No=Ticket.Passenger_No AND Airline.Airline_No=Ticket.Airline_No AND Class.Class_No=Ticket.Class_No
END

EXECUTE passenger_details

SQL Server 中的上述存储过程成功运行。

然后我尝试在 Oracle PL/SQL 中执行相同的存储过程，如下所示：

CREATE OR REPLACE PROCEDURE passenger_details
(p_passenger_details OUT SYS_REFCURSOR) 
AS 
BEGIN 
OPEN p_passenger_details FOR
SELECT Full_Name, Age, Nationality, Category, Airline_Name, Class_Type
FROM Passenger, Ticket, Airline, Class
WHERE Passenger.Passenger_No=Ticket.Passenger_No AND Airline.Airline_No=Ticket.Airline_No AND Class.Class_No=Ticket.Class_No;
END passenger_details;

以上Oracle PL/SQL中的存储过程编译成功。

然后我尝试执行它，如下所示：

SET SERVEROUTPUT ON;
EXECUTE passenger_details;

在尝试执行存储过程时，我收到以下错误消息，如下所示：

Error …

这是我创建的表：

CREATE TABLE Toy
(Toy_No NUMBER PRIMARY KEY,
 Toy_Name VARCHAR(30) NOT NULL
 );

这是我创建的序列：

CREATE SEQUENCE toy_seq
MINVALUE 1
START WITH 1
INCREMENT BY 1
CACHE 20;

然后我尝试使用输出参数创建一个简单的存储过程：

CREATE OR REPLACE PROCEDURE insert_toys(toy_id OUT NUMBER,toy_name VARCHAR(30))
AS
BEGIN 
toy_id := seq_toy.NEXTVAL;
INSERT INTO Toy (Toy_No,Toy_Name)
VALUES (toy_id,toy_name);
END;

但我收到编译错误。错误可能在哪里？

这些是我创建并插入了一些值的表：

CREATE TABLE DEPARTMENT
(DEPARTMENT_ID NUMBER PRIMARY KEY,
 DEPARTMENT_NAME VARCHAR(30) NOT NULL
 );

CREATE TABLE EMPLOYEES
(EMPLOYEE_ID NUMBER PRIMARY KEY,
 FIRST_NAME VARCHAR(20) NOT NULL,
 LAST_NAME VARCHAR(25) NOT NULL,
 EMAIL VARCHAR(25) NOT NULL,
 PHONE_NUMBER VARCHAR(20) NOT NULL,
 HIRE_DATE DATE NOT NULL,
 JOB_ID NUMBER NOT NULL,
 SALARY DECIMAL NOT NULL,
 DEPARTMENT_ID NUMBER NOT NULL,
 CONSTRAINT emp_job_fk FOREIGN KEY(JOB_ID) REFERENCES JOBS(JOB_ID),
 CONSTRAINT emp_department_fk FOREIGN KEY(DEPARTMENT_ID) REFERENCES DEPARTMENT(DEPARTMENT_ID)
 );

INSERT INTO DEPARTMENT (DEPARTMENT_ID,DEPARTMENT_NAME)
VALUES(1,'IT');
INSERT INTO DEPARTMENT (DEPARTMENT_ID,DEPARTMENT_NAME)
VALUES(2,'Sales');
INSERT INTO DEPARTMENT (DEPARTMENT_ID,DEPARTMENT_NAME)
VALUES(3,'Accounting'); …
