--源端创建数据
[rootmysql8p /]# mysql -uroot -proot -h172.18.12.66
mysql show databases;
--------------------
| Database |
--------------------
| information_schema |
| mysql |
| performance_schema |
| rptdb |
| sys |
--------------------
5 rows in set (0.01 sec)mysql use rptdb
mysql show tables;1.新建表插入数据验证数据
DROP TABLE IF EXISTS Customers;
CREATE TABLE IF NOT EXISTS Customers(cust_id VARCHAR(255) DEFAULT NULL
);
INSERT Customers VALUES (A),(B),(C);##目标端数据同步
mysql show tables;
-----------------
| Tables_in_rptdb |
-----------------
| Customers |
-----------------
1 row in set (0.00 sec)mysql select * from Customers;
---------
| cust_id |
---------
| A |
| B |
| C |
---------
3 rows in set (0.00 sec)2.源端建表,验证数据
drop table if exists product_tb;
CREATE TABLE product_tb(
item_id char(10) NOT NULL,
style_id char(10) NOT NULL,
tag_price int(10) NOT NULL,
inventory int(10) NOT NULL
);##目标端数据同步
mysql show tables;
-----------------
| Tables_in_rptdb |
-----------------
| Customers |
| product_tb |
-----------------
2 rows in set (0.00 sec)3.源端新建一列验证数据
ALTER TABLE product_tb ADD COLUMN address VARCHAR(50);
mysql show create table product_tb\G
*************************** 1. row ***************************Table: product_tb
Create Table: CREATE TABLE product_tb (item_id char(10) NOT NULL,style_id char(10) NOT NULL,tag_price int NOT NULL,inventory int NOT NULL,address varchar(50) DEFAULT NULL
) ENGINEInnoDB DEFAULT CHARSETutf8mb4 COLLATEutf8mb4_0900_ai_ci
1 row in set (0.00 sec)##目标端数据同步
mysql show create table product_tb\G
*************************** 1. row ***************************Table: product_tb
Create Table: CREATE TABLE product_tb (item_id char(10) NOT NULL,style_id char(10) NOT NULL,tag_price int NOT NULL,inventory int NOT NULL,address varchar(50) DEFAULT NULL
) ENGINEInnoDB DEFAULT CHARSETutf8mb4 COLLATEutf8mb4_0900_ai_ci
1 row in set (0.00 sec)以上验证可以看到DDL和DML都可以同步。
