JAVA存储过程调用

创建需要的测试表:create table Test(tid varchar2(10),tname varchar2(10));

第一种情况：无返回值.

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

begin

insert into test value(param1,param2);

end;

Java调用代码:

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){

}
}
}

}

第二种情况：有返回值的存储过程(返回值非列表).

存储过程为:
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调用代码：

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){

}
}
}

}

第三种情况：返回列表.

由于oracle存储过程没有返回值，它的所有返回值都是通过out参数来替代的，列表同样也不例外，但由于是集合，所以不能用一般的参数，必须要用pagkage了.要分两部分来写：
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调用代码：

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){

}
}
}

}

Hibernate调用oracle存储过程

　this.pnumberManager.getHibernateTemplate().execute(

　　new HibernateCallback() ...{

　　 public Object doInHibernate(Session session)

　　 throws HibernateException, SQLException ...{

　　 CallableStatement cs = session.connection().prepareCall("{call modifyapppnumber_remain(?)}");

　　 cs.setString(1, foundationid);

　　 cs.execute();

　　 return null;

　　}

　});
