MySQL export table structure, execute .sql file to import structure or data

1. MySQL exports different types of table structures

1.1 Export structure does not export data

mysqldump　-h 主机地址 -u　root　-p 密码 -d　数据库名　　>　xxx.sql　　# 加 -d 参数

If you find that the data will still be exported after adding -dthe parameter , you can -dreplace the parameter with--no-data

1.2 Exporting data does not export structure

mysqldump　-h 主机地址 -u　root　-p 密码 -t　数据库名　　>　xxx.sql

1.3 Export data and table structure

mysqldump -h 主机地址 -u　root　-p 密码　数据库名　　>　xxx.sql　# 不加 -d 参数

1.4 Export the structure of a specific table

Multiple tables (test1, test2, test3) structure and table data are separated by spaces

mysqldump -h 主机地址  -u　root　-p 密码 -B　数据库名　--table　表1,表2　　>　xxx.sql

1.5 May report an error

error 1

mysqldump: Got error: 1105: [parser:1149]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use when using LOCK TABLES

The solution is to add --skip-lock-tablesthe parameter

error 2

Unknown table 'column_statistics' in information_schema (1109)

The solution is to add --column-statistics=0parameters

2. Execute the .sql file and import data

2.1 Solution 1: Use the source command after logging in to mysql

use my_test_db # 进入某个数据库
source xxx/xx/xx.sql

2.2 Solution 2: Use the mysql command directly

The shell directly enters the following command

mysql -h 主机地址 -u root -p my_test_db < xxx/xx/xx.sql

3. Back up the database

mysqldump　数据库名　>数据库备份名
mysqldump　-A　-u用户名　-p密码　数据库名>数据库备份名
mysqldump　-d　-A　--add-drop-table　-uroot　-p　>xxx.sql

4. Prompt

If Baidu or Google can't find the solution, why not ask chatgpt directly, maybe it will have a solution.

5, Reference:

Mysql batch export table structure (data)

Mysql mysqldump only exports the table structure or only the data export method

mysqldump export error column_statistics

Mysql uses commands to execute sql files

Mysql database import sql file Mysql import and export method of .sql file
