MySQL迁移到KingbaseES数据库

MySQL 迁移到 KingbaseES 数据库

参考连接：https://help.kingbase.com.cn/v8/development/develop-transfer/transplant-mysql/transplant-mysql-3.html

一、迁移前准备

1. KingbaseES 创建与MySQL 同名用户

create user qkl_dev password 'xxxxxx';

2. KingbaseES 创建与MySQL 同名库

create database digitalone_dev owner qkl_dev;

3. 将数据库授权给qkl_dev用户

grant all on database digitalone_dev to qkl_dev ;

二、启动/访问 KDTS 数据库迁移工具

1. 启动

cd /opt/Kingbase/ES/V8/ClientTools/guitools/KDts/KDTS-WEB/bin
./startup.sh

2. 访问

浏览器访问：http://服务器ip:8080
用户名：kingbase
密码：kingbase
# 默认是填充的

三、使用KDTS 迁移

1. 添加数据源

1.1 添加源数据库

数据源管理 --> 源数据库 --> 新建 --> 填写连接信息 – > 确定（确定前建议点击测试，避免连接有问题）

1.2 添加目标数据库

数据源管理 --> 源数据库 --> 新建 --> 填写连接信息 – > 确定 （连接名称不能重复）

2. 建立迁移任务

迁移任务管理 – > 迁移任务 --> 新建 --> 选择相关信息 --> 选择模式 --> 选择迁移对象(点击红框可选择不迁移哪些表) --> 参数配置(自行选择) --> 保存/保存并迁移

问题：

varchar和numeric不能union，需要手动强制转一下

区别：
union select “bdc_request_statistics_zm”.“id”

union select “bdc_request_statistics_zm”.“id”::numeric(32,0)
