MYSQL存储过程查询返回结果处理方法

一、MYSQL表创建语句


1.1  创建表

SET FOREIGN_KEY_CHECKS=0;

DROP TABLE IF EXISTS `testproc`;

CREATE TABLE `testproc` (

  `id` int(4) NOT NULL,

  `name` varchar(100) DEFAULT NULL,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;


1.2  插入数据

INSERT INTO `testproc` VALUES ('1', '第一条记录');

INSERT INTO `testproc` VALUES ('2', 'efgh');

INSERT INTO `testproc` VALUES ('3', 'ijklmn');

INSERT INTO `testproc` VALUES ('4', 'zxvb');

INSERT INTO `testproc` VALUES ('5', 'uiop');

INSERT INTO `testproc` VALUES ('6', '222');

INSERT INTO `testproc` VALUES ('7', '8888');

INSERT INTO `testproc` VALUES ('9', '第9条记录');

INSERT INTO `testproc` VALUES ('10', '第10条记录');

INSERT INTO `testproc` VALUES ('11', '第11条记录');

INSERT INTO `testproc` VALUES ('12', '第12条记录');

1.3  创建存储过程

CREATE PROCEDURE test_proc_multi_select()

BEGIN

         select * from testproc;

         select * from testproc where id=1;

END;

二、JAVA相关代码

注意要导入MYSQL包

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;


import com.mysql.jdbc.CallableStatement;


public class Test1 {

public static final String DBDRIVER = "com.mysql.jdbc.Driver";

public static final String DBURL = "jdbc:mysql://127.0.0.1:3306/test1";

public static final String DBUSER = "root";

public static final String DBPASS = "123456";


public static void main(String[] args) {

Connection con = null;

CallableStatement cs;

try {

        Class.forName(DBDRIVER);

        con = DriverManager.getConnection(DBURL, DBUSER, DBPASS);

        String sql = "{call test_proc_multi_select()}";

        cs = (CallableStatement) con.prepareCall(sql);

        boolean hadResults = cs.execute();

        int i = 0;

        while (hadResults) {

            System.out.println("result No:----" + (++i));

            ResultSet rs = cs.getResultSet();

            while (rs != null && rs.next()) {

            int id1 = rs.getInt(1);

            String name1 = rs.getString(2);

            System.out.println(id1 + ":" + name1);

            }

        hadResults = cs.getMoreResults(); // 检查是否存在更多结果集

        }

} catch (ClassNotFoundException e) {

        e.printStackTrace();

} catch (SQLException e) {

        e.printStackTrace();

} finally {

    try {

        con.close();

    } catch (SQLException e) {

        e.printStackTrace();

    }

}

}


}
