Java調用Oracle存儲過程

創建需要的測試表:create table Test(tid varchar2(10),tname varchar2(10));

第一種情況：無返回值

create or replace procedure test_a(param1 in varchar2,param2 in varchar2) as

begin

insert into test value(param1,param2);

end;

Java調用代碼:

package com.test;

import java.sql.*;

import java.io.*;

import java.sql.*;

public class TestProcA

{

public TestProcA(){



}



public static void main(String []args)

{



ResultSet rs = null;

Connection conn = null;

CallableStatement proc = null;



try{

Class.forName("oracle.jdbc.driver.OracleDriver");

conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:test", "test", "test");

proc = conn.prepareCall("{ call test_a(?,?) }");

proc.setString(1, "1001");

proc.setString(2, "TestA");

proc.execute();

}catch(Exception e){

e.printStackTrace();

}finally{

try{

if(null!=rs){

rs.close();

if(null!=proc){

proc.close();

}

if(null!=conn){

conn.close();

}

}

}catch(Exception ex){

}

}

}

}

第二種情況：有返回值的存儲過程(返回值非列表).

存儲過程爲:

create or replace procedure test_b(param1 in varchar2,param2 out varchar2)

as

begin

select tname into param2 from test where tid=param1;

end;

Java調用代碼：

package com.test;

import java.sql.*;

import java.io.*;

import java.sql.*;

public class TestProcB

{

public TestProcB(){



}



public static void main(String []args)

{



Connection conn = null;

CallableStatement proc = null;



try{

Class.forName("oracle.jdbc.driver.OracleDriver");

conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:test", "test", "test");

proc = conn.prepareCall("{ call test_b(?,?) }");

proc.setString(1, "1001");

proc.registerOutParameter(2, Types.VARCHAR);

proc.execute();

System.out.println("Output is:"+proc.getString(2));

}catch(Exception e){

e.printStackTrace();

}finally{

try{

if(null!=proc){

proc.close();

}

if(null!=conn){

conn.close();

}



}catch(Exception ex){

}

}

}

}

第三種情況：返回列表.

由於oracle存儲過程沒有返回值，它的所有返回值都是通過out參數來替代的，列表同樣也不例外，但由於是集合，所以不能用一般的參數，必須要用pagkage了.要分兩部分來寫：

create or replace package tpackage as

type t_cursor is ref cursor;

procedure test_c(c_ref out t_cursor);

end ;

create or replace package body tpackage as

procedure test_c(c_ref out t_cursor) is

begin

open c_ref for select * from test;

end test_c;

end tpackage;

Java調用代碼：

package com.test;

import java.sql.*;

import java.io.*;

import java.sql.*;

public class TestProcB

{

public TestProcB(){



}



public static void main(String []args)

{



Connection conn = null;

CallableStatement proc = null;

ResultSet rs = null;

try{

Class.forName("oracle.jdbc.driver.OracleDriver");

conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:test", "test", "test");

proc = conn.prepareCall("{? = call tpackage.test_b(?) }");



proc.registerOutParameter(1,OracleTypes.CURSOR);

proc.execute();

while(rs.next()){

System.out.println(rs.getObject(1)+"\t"+rs.getObject(2));

}

}catch(Exception e){

e.printStackTrace();

}finally{

try{

if(null!=rs){

rs.close();

if(null!=proc){

proc.close();

}

if(null!=conn){

conn.close();

}

}

}catch(Exception ex){

}

}

}

}
