java调用存储过程返回值_Java调用存储过程（有返回值）

1：创建存储过程

此存储过程通过传入的参数(Name)，返回一个参数(address)。

create or replace procedure demo_procedure(namedemo in varchar2,addressdemo out varchar2)

as

begin

select address into addressdemo from system.demo where name=namedemo;

end;

2：java代码：

import java.sql.CallableStatement;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import java.sql.Types;

public class TestProcedureTwo {

public TestProcedureTwo() {

}

public static void main(String[] args ){

String driver = "oracle.jdbc.driver.OracleDriver";

String strUrl = "jdbc:oracle:thin:@localhost:1521:myoracle";

Statement stmt = null;

ResultSet rs = null;

Connection conn = null;

try {

Class.forName(driver);

conn = DriverManager.getConnection(strUrl, "system", "admin");

CallableStatement proc = null;

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

proc.setString(1, "kalision");

proc.registerOutParameter(2, Types.VARCHAR);

proc.execute();

String testPrint = proc.getString(2);

System.out.println("存储过程返回的值是："+testPrint);

}

catch (SQLException ex2) {

ex2.printStackTrace();

}

catch (Exception ex2) {

ex2.printStackTrace();

}

finally{

try {

if(rs != null){

rs.close();

if(stmt!=null){

stmt.close();

}

if(conn!=null){

conn.close();

}

}

}

catch (SQLException ex1) {

}

}

}

}

注意：记得导入jdbc驱动的jar包。
