# 数据源Doris到目标Doris数据同步

本示例主要演示从Doris读取数据，写入Doris库中。

主要步骤如下：

准备数据
新建同步作业
拖拽图元
运行
查看数据
提交版本

# 准备数据

创建 Doris 源数据库 testdb，在源数据库 testdb 中创建一个表 orderinfo。

drop table if exists `orderinfo`;
CREATE TABLE `orderinfo` (
  `ordercode` varchar(32) NOT NULL COMMENT "订单号",
  `amount` int(11) NULL COMMENT "数量",
  `price` varchar(32) NULL COMMENT "价格",
  `manufacturer2` varchar(100) NULL COMMENT "厂商",
  `createtime` date NULL COMMENT "创建时间",
  `createuser` varchar(32) NULL COMMENT "创建人",
  `updatetime` datetime NULL COMMENT "更新时间"
) ENGINE=OLAP 
UNIQUE KEY(`ordercode`)
DISTRIBUTED BY HASH(`ordercode`)
PROPERTIES ('replication_num'='1');

INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('001', 1000, '5000', '星云制造', '2023-10-25', '张无忌4', '2024-01-04 12:00:00');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('002', 50022, '1000', '西安金属', '2018-12-13', '张无忌4', '2018-12-13 00:00:00');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('003', 1500, '7000', '枫禾林木', '2018-12-13', '魏雨', '2024-01-11 00:00:00');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('004', 1000, '75000', '星峰', '2019-01-13', '王林', '2019-01-13 12:23:01');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('005', 1300, '8000', '天威科技', '2018-12-13', '王林', '2018-12-13 00:00:00');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('006', 2000, '5000', '微云科', '2023-10-25', '王林', '2023-10-25 00:00:00');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('007', 3000, '9001', '西安金属', '2024-12-13', '王强', '2020-12-13 11:11:11');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('008', 12300, '11589', '星峰', '2018-12-13', '王强', '2024-02-04 12:00:00');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('009', 5100, '22909', '星云制造', '2018-12-13', '魏雨', '2018-12-13 23:59:59');
INSERT INTO orderinfo
(ordercode, amount, price, manufacturer2, createtime, createuser, updatetime)
VALUES('010', 1800, '15900', '天威科技', '2018-12-13', '魏雨', '2018-12-13 00:00:00');

创建 Doris 目标数据库 testdb2，在目标数据库 testdb2中创建一个表 orderinfo，如果表已经存在可以忽略该步骤。

drop table if exists `orderinfo`;
CREATE TABLE `orderinfo2` (
  `ordercode` varchar(32) NOT NULL COMMENT "订单号",
  `amount` int(11) NULL COMMENT "数量",
  `price` varchar(32) NULL COMMENT "价格",
  `manufacturer2` varchar(100) NULL COMMENT "厂商",
  `createtime` date NULL COMMENT "创建时间",
  `createuser` varchar(32) NULL COMMENT "创建人",
  `updatetime` datetime NULL COMMENT "更新时间"
) ENGINE=OLAP 
UNIQUE KEY(`ordercode`)
DISTRIBUTED BY HASH(`ordercode`)
PROPERTIES ('replication_num'='1');
