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?

--创建表格

CREATE TABLE STOCK_PRICES(

RIC VARCHAR(6) PRIMARY KEY,

PRICE NUMBER(7,2),

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?

--插入数据

INSERTINTO stock_prices values('1111',1.0,SYSDATE);

INSERTINTO stock_prices values('1112',2.0,SYSDATE);

INSERTINTO stock_prices values('1113',3.0,SYSDATE);

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?

--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;

--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?

--创建存储过程

CREATEORREPLACEPROCEDURE 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;

--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?

--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;

--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?

import java.sql.*;

import oracle.jdbc.OracleCallableStatement;

import oracle.jdbc.OracleTypes;

/* 本例是通过调用oracle的存储过程来返回结果集:

* oracle 9i、10G 的jdbc由1个jar包组成：classes12.zip

*/

publicclass 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

init();

// mysid：必须为要连接机器的sid名称，否则会包以下错：

}

publicvoid 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 ");

}

}

publicstaticvoid main(String args[])// 自己替换［］

{

new JDBCoracle10G_INVOKEPROCEDURE();

}

}

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

/* 本例是通过调用oracle的存储过程来返回结果集:

public class JDBCoracle10G_INVOKEPROCEDURE {
Connection conn = null;

} 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

JDBCoracle10G_INVOKEFUNCTION.java

[java] view plaincopyprint?

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

*/

publicclass 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 );

}

publicvoid 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 ");

}

}

publicstaticvoid main(String args[])// 自己替换［］

{

new JDBCoracle10G_INVOKEFUNCTION();

}

}
