java数据存储过程 java数据库存储过程

java 使用 mysql 存储过程

 

1、使用最简单的存储过程

 

存储过程如下

DELIMITER $ 
CREATE procedure pro_test2()
BEGIN
	SELECT * from point;
END $

 

 java中调用

 

public void testProcedureGetAll() throws Exception{
		Connection conn = JDBCUtil.getConnection();
		CallableStatement cstmt = conn.prepareCall("{call pro_test2}");
		ResultSet rs = cstmt.executeQuery();
		while(rs.next()){
			System.out.println(rs.getInt(1)+"--->"+rs.getInt(2));
		}
		
		if(null != rs){
			rs.close();
		}
		if(null != cstmt){
			cstmt.close();
		}
		if(null != conn){
			conn.close();
		}
	}

 

 

2、调用带参数的存储过程

 

存储过程如下 

DELIMITER $ 
create procedure pro_test1(in inputId INT)
BEGIN
	SELECT * from bookinfor b where b.id > inputId;
END $

 

 

java中调用

 

public void testProcedureGetByInputParam() throws Exception{
		Connection conn = JDBCUtil.getConnection();
		CallableStatement cstmt = conn.prepareCall("{ call pro_test1(2) }");
		ResultSet rs = cstmt.executeQuery();
		while(rs.next()){
			System.out.println("Id:"+rs.getInt("id")+"; bookName:"+rs.getString("bookName")+"; publish:"+rs.getDate("publish"));
		}
		if(null != rs){
			rs.close();
		}
		if(null != cstmt){
			cstmt.close();
		}
		if(null != conn){
			conn.close();
		}
	}

 

 

JDBCUtil

import java.sql.Connection;
import java.sql.DriverManager;

public class JDBCUtil {
	private static final String DRIVER = "com.mysql.jdbc.Driver";
	private static final String URL = "jdbc:mysql://localhost:3306/XXXXX";
	private static final String USER = "root";
	private static final String PASSWORD = "123456";
	
	public static Connection getConnection(){
		Connection conn = null;
		try {
			Class.forName(DRIVER);
			conn = DriverManager.getConnection(URL, USER, PASSWORD);
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		return conn;
	}
	
	
}
