java存储过程

转载：http://developer.51cto.com/art/200906/130448.htm

 创建需要的测试表:create table Test(tidvarchar2(10),tnamevarchar2(10));

第一种情况：无返回值.

 create or replace proceduretest_a(param1invarchar2,param2invarchar2)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("{calltest_a(?,?)}");
 proc.setString(1,"1001");
 proc.setString(2,"TestA");
 proc.execute();
 }catch(Exceptione){
 e.printStackTrace();
 }finally{
 try{
 if(null!=rs){
 rs.close();

 if(null!=proc){
 proc.close();
 }
 if(null!=conn){
 conn.close();
 }
 }
 }catch(Exceptionex){
 }
 }
 }
}

 

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 procedur etest_b(param1invarchar2,param2outvarchar2)
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("{calltest_b(?,?)}");
proc.setString(1,"1001");
proc.registerOutParameter(2,Types.VARCHAR);
proc.execute();
System.out.println("Outputis:"+proc.getString(2));
}catch(Exceptione){
e.printStackTrace();
}finally{
try{

if(null!=proc){
proc.close();
}

if(null!=conn){
conn.close();
}

}catch(Exceptionex){

}
}
}
}

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 packaget package as
typet_cursorisrefcursor;
proceduretest_c(c_refoutt_cursor);
end;

createorreplacepackagebodytpackageas
proceduretest_c(c_refoutt_cursor)is
begin
openc_refforselect*fromtest;
endtest_c;
endtpackage;

Java调用代码：

package com.test;
import java.sql.*;
import java.io.*;
import java.sql.*;
public class TestProcB
{
public TestProcB(){
}
publics tatic 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("{?=calltpackage.test_b(?)}");

proc.registerOutParameter(1,OracleTypes.CURSOR);
proc.execute();
while(rs.next()){
System.out.println(rs.getObject(1)+"\t"+rs.getObject(2));
}
}catch(Exceptione){
e.printStackTrace();
}finally{
try{
if(null!=rs){
rs.close();
if(null!=proc){
proc.close();
}
if(null!=conn){
conn.close();
}
}
}catch(Exceptionex){
}
}
}
}

Hibernate调用oracle存储过程

this.pnumberManager.getHibernateTemplate().execute(
　newHibernateCallback()...{
public Object doInHibernate(Sessionsession)
throws HibernateException,SQLException...{
 CallableStatementcs=session.connection().prepareCall("{callmodifyapppnumber_remain(?)}");
cs.setString(1,foundationid);
cs.execute();
returnnull;
}
　});
