Java调用Oracle存储过程

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){

           }

        }

   }
