java下实现调用oracle的存储过程和函数

在oracle下创建一个test的账户，然后

1.创建表：STOCK_PRICES

 

[cpp] view plaincopyprint?
  1. --创建表格 
  2. CREATE TABLE STOCK_PRICES( 
  3.     RIC VARCHAR(6) PRIMARY KEY, 
  4.     PRICE NUMBER(7,2), 
  5.     UPDATED DATE );  
--创建表格
CREATE TABLE STOCK_PRICES(
    RIC VARCHAR(6) PRIMARY KEY,
    PRICE NUMBER(7,2),
    UPDATED DATE );

 

2.插入测试数据：

 

[sql] view plaincopyprint?
  1. --插入数据 
  2. INSERTINTO stock_prices values('1111',1.0,SYSDATE); 
  3. INSERTINTO stock_prices values('1112',2.0,SYSDATE); 
  4. INSERTINTO stock_prices values('1113',3.0,SYSDATE); 
  5. INSERTINTO stock_prices values('1114',4.0,SYSDATE);  
--插入数据
INSERT INTO stock_prices values('1111',1.0,SYSDATE);
INSERT INTO stock_prices values('1112',2.0,SYSDATE);
INSERT INTO stock_prices values('1113',3.0,SYSDATE);
INSERT INTO stock_prices values('1114',4.0,SYSDATE);

 

3.建立一个返回游标：

PKG_PUB_UTILS

 

[cpp] view plaincopyprint?
  1. --建立一个返回游标 
  2. CREATE OR REPLACE PACKAGE PKG_PUB_UTILS IS 
  3.     --动态游标 
  4.     TYPE REFCURSOR IS REF CURSOR; 
  5. END PKG_PUB_UTILS;  
--建立一个返回游标
CREATE OR REPLACE PACKAGE PKG_PUB_UTILS IS
    --动态游标
    TYPE REFCURSOR IS REF CURSOR;
END PKG_PUB_UTILS;

4.创建和存储过程：P_GET_PRICE

 

 

[sql] view plaincopyprint?
  1. --创建存储过程 
  2. CREATEORREPLACEPROCEDURE P_GET_PRICE 
  3. ( 
  4.   AN_O_RET_CODE OUT NUMBER, 
  5.   AC_O_RET_MSG  OUT VARCHAR2, 
  6.   CUR_RET OUT PKG_PUB_UTILS.REFCURSOR, 
  7.   AN_I_PRICE IN NUMBER 
  8. )  
  9. IS 
  10. BEGIN 
  11.     AN_O_RET_CODE := 0; 
  12.     AC_O_RET_MSG  := '操作成功'; 
  13.      
  14.     OPEN CUR_RET FOR 
  15.         SELECT * FROM STOCK_PRICES WHERE PRICE<AN_I_PRICE; 
  16. EXCEPTION 
  17.     WHEN OTHERS THEN 
  18.         AN_O_RET_CODE := -1; 
  19.         AC_O_RET_MSG  := '错误代码:' || SQLCODE || CHR(13) || '错误信息:' || SQLERRM; 
  20. END P_GET_PRICE;  
--创建存储过程
CREATE OR REPLACE PROCEDURE P_GET_PRICE
(
  AN_O_RET_CODE OUT NUMBER,
  AC_O_RET_MSG  OUT VARCHAR2,
  CUR_RET OUT PKG_PUB_UTILS.REFCURSOR,
  AN_I_PRICE IN NUMBER
) 
IS
BEGIN
    AN_O_RET_CODE := 0;
    AC_O_RET_MSG  := '操作成功';
    
    OPEN CUR_RET FOR
        SELECT * FROM STOCK_PRICES WHERE PRICE<AN_I_PRICE;
EXCEPTION
    WHEN OTHERS THEN
        AN_O_RET_CODE := -1;
        AC_O_RET_MSG  := '错误代码:' || SQLCODE || CHR(13) || '错误信息:' || SQLERRM;
END P_GET_PRICE;

5.创建函数：

 

[cpp] view plaincopyprint?
  1. --创建函数：F_GET_PRICE 
  2. CREATE OR REPLACE FUNCTION F_GET_PRICE(v_price IN NUMBER) 
  3.     RETURN PKG_PUB_UTILS.REFCURSOR 
  4. AS 
  5.     stock_cursor PKG_PUB_UTILS.REFCURSOR; 
  6. BEGIN 
  7.     OPEN stock_cursor FOR 
  8.     SELECT * FROM stock_prices WHERE price < v_price; 
  9.     RETURN stock_cursor; 
  10. END;  
--创建函数：F_GET_PRICE
CREATE OR REPLACE FUNCTION F_GET_PRICE(v_price IN NUMBER)
    RETURN PKG_PUB_UTILS.REFCURSOR
AS
    stock_cursor PKG_PUB_UTILS.REFCURSOR;
BEGIN
    OPEN stock_cursor FOR
    SELECT * FROM stock_prices WHERE price < v_price;
    RETURN stock_cursor;
END;

6.JAVA调用存储过程返回结果集

JDBCoracle10G_INVOKEPROCEDURE.java

[java] view plaincopyprint?
  1. import java.sql.*; 
  2. import oracle.jdbc.OracleCallableStatement;
