oracle 的存储过程在java怎么调用

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，然后按一下步骤执行：
1.创建表：STOCK_PRICES

--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：

--插入数据尺含
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

--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

--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 PRICEEXCEPTION
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：

--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
代码示例：JDBCoracle10G_INVOKEPROCEDURE.java

import java.sql.*;
import oracle.jdbc.OracleCallableStatement;
import oracle.jdbc.OracleTypes;

/* 本例是通过调用oracle的存储过程来返埋困腔回结果集:
* oracle 9i、弯衫10G 的jdbc由1个jar包组成：classes12.zip
*/
public class JDBCoracle10G_INVOKEPROCEDURE {
Connection conn = null;
Statement statement = null;
ResultSet rs = null;
CallableStatement stmt = null;

String driver;
String url;
String user;
String pwd;
String sql;
String in_price;

public JDBCoracle10G_INVOKEPROCEDURE()
{
driver = "oracle.jdbc.driver.OracleDriver";
url = "jdbc:oracle:thin:@localhost:1521:ORCL";
// oracle 用户
user = "test";
// oracle 密码
pwd = "test";
init();
// mysid：必须为要连接机器的sid名称，否则会包以下错：
// java.sql.SQLException: Io 异常: Connection
// refused(DESCRIPTION=(TMP=)(VSNNUM=169870080)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
// 参考连接方式:
// Class.forName( "oracle.jdbc.driver.OracleDriver" );
// cn = DriverManager.getConnection(
// "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd );

}

public void init() {
System.out.println("oracle jdbc test");
try {
Class.forName(driver);
System.out.println("driver is ok");
conn = DriverManager.getConnection(url, user, pwd);
System.out.println("conection is ok");
statement = conn.createStatement();
// conn.setAutoCommit(false);
// 输入参数
in_price = "3.0";
// 调用函数
stmt = conn.prepareCall("call P_GET_PRICE(?,?,?,?)");
stmt.registerOutParameter(1, java.sql.Types.FLOAT);
stmt.registerOutParameter(2, java.sql.Types.CHAR);
stmt.registerOutParameter(3, oracle.jdbc.OracleTypes.CURSOR);
stmt.setString(4, in_price);
stmt.executeUpdate();
int retCode = stmt.getInt(1);
String retMsg = stmt.getString(2);
if (retCode == -1) { // 如果出错时，返回错误信息
System.out.println("报错！");
} else {
// 取的结果集的方式一：
rs = ((OracleCallableStatement) stmt).getCursor(3);
// 取的结果集的方式二：
// rs = (ResultSet) stmt.getObject(3);
String ric;
String price;
String updated;
// 对结果进行输出
while (rs.next()) {
ric = rs.getString(1);
price = rs.getString(2);
updated = rs.getString(3);
System.out.println("ric:" + ric + ";-- price:" + price
+ "; --" + updated + "; ");
}
}

} catch (Exception e) {
e.printStackTrace();
} finally {
System.out.println("close ");
}
}

public static void main(String args[])// 自己替换［］
{
new JDBCoracle10G_INVOKEPROCEDURE();
}
}

7.开发JAVA调用函数返回结果集
代码示例：JDBCoracle10G_INVOKEFUNCTION.java

import java.sql.*;
import oracle.jdbc.OracleCallableStatement;
import oracle.jdbc.OracleTypes;

/*
/* 本例是通过调用oracle的函数来返回结果集:
* oracle 9i、10G 的jdbc由1个jar包组成：classes12.zip
*/
public class JDBCoracle10G_INVOKEFUNCTION {
Connection conn = null;
Statement statement = null;
ResultSet rs = null;
CallableStatement stmt = null;

String driver;
String url;
String user;
String pwd;
String sql;
String in_price;

public JDBCoracle10G_INVOKEFUNCTION()
{
driver = "oracle.jdbc.driver.OracleDriver";
url = "jdbc:oracle:thin:@localhost:1521:ORCL";
// oracle 用户
user = "test";
// oracle 密码
pwd = "test";
init();
// mysid：必须为要连接机器的sid名称，否则会包以下错：
// java.sql.SQLException: Io 异常: Connection
// refused(DESCRIPTION=(TMP=)(VSNNUM=169870080)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
// 参考连接方式:
// Class.forName( "oracle.jdbc.driver.OracleDriver" );
// cn = DriverManager.getConnection(
// "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd );
}

public void init() {
System.out.println("oracle jdbc test");
try {
Class.forName(driver);
System.out.println("driver is ok");
conn = DriverManager.getConnection(url, user, pwd);
System.out.println("conection is ok");
statement = conn.createStatement();
// conn.setAutoCommit(false);
// 输入参数
in_price = "5.0";
// 调用函数
stmt = conn.prepareCall("{? = call F_GET_PRICE(?)}");
// stmt.registerOutParameter(1, java.sql.Types.FLOAT);
// stmt.registerOutParameter(2, java.sql.Types.CHAR);
stmt.registerOutParameter(1, oracle.jdbc.OracleTypes.CURSOR);
stmt.setString(2, in_price);
stmt.executeUpdate();
// 取的结果集的方式一：
rs = ((OracleCallableStatement) stmt).getCursor(1);
// 取的结果集的方式二：
// rs = (ResultSet) stmt.getObject(1);
String ric;
String price;
String updated;

while (rs.next()) {
ric = rs.getString(1);
price = rs.getString(2);
updated = rs.getString(3);
System.out.println("ric:" + ric + ";-- price:" + price + "; --"
+ updated + "; ");
}

} catch (Exception e) {
e.printStackTrace();
} finally {
System.out.println("close ");
}
}

public static void main(String args[])// 自己替换［］
{
new JDBCoracle10G_INVOKEFUNCTION();
}
}
