Oracle存储过程的编写以及程序的实现

-- 创建表
CREATE TABLE sys_user(
  ID NUMBER PRIMARY KEY,
  USERNAME VARCHAR2(20) NOT NULL,
  PASSWORD VARCHAR2(20) NOT NULL,
  SEX VARCHAR2(20) NOT NULL,
  STATUS VARCHAR2(20) NOT NULL
);
-- 创建存储过程（新增一条用户信息）
CREATE OR REPLACE PROCEDURE P_USER_ADD(
P_ID IN NUMBER,
P_USERNAME IN VARCHAR2,
P_PASSWORD IN VARCHAR2,
P_SEX IN VARCHAR2,
P_STATUS IN VARCHAR2
) 
BEGIN
INSERT INTO SYS_USER VALUES(P_ID,P_USERNAME,P_PASSWORD,P_SEX,P_STATUS);
END;
-- 创建存储过程（删除一条用户信息）
CREATE OR REPLACE PROCEDURE P_USER_DEL 
(
  P_ID IN NUMBER  
, X_OUT_ID OUT NUMBER  
) AS 
BEGIN
  DELETE SYS_USER WHERE ID=P_ID;
  X_OUT_ID:=0;
  EXCEPTION
  WHEN OTHERS THEN 
  X_OUT_ID:=-1;
END;
-- 创建存储过程（查询全部用户信息）
CREATE OR REPLACE PROCEDURE P_USER_ALL(
X_OUT_RECORD OUT NUMBER,
X_OUT_CURSOR OUT SYS_REFCURSOR
) AS  
BEGIN  
    OPEN x_out_cursor FOR
        SELECT * FROM SYS_USER;   
    x_out_record := 0;   
    EXCEPTION   
    WHEN OTHERS THEN
        x_out_record := -1;   
END;
