There are 3 common ways to import an SQL file into MYSQL:
- Run
mysql -u USER -p DATABASE_NAME < PATH/TO/FILE.sqlin the command line (or terminal). - Use MySQL Workbench to import SQL files.
- Use a web-based database manager such as phpMyAdmin.
Let us walk through these methods step-by-step in this guide – Read on!
TABLE OF CONTENTS
IMPORT SQL FILE IN COMMAND LINE
The easiest method, doesn’t even need to install any tools – Just use the command line to import SQL files.
IMPORT COMMAND EXAMPLE
D:\http\>mysql -u root -p test < d:\http\test.sql
Enter password:
D:\http\>Yep, it’s that simple, just run the command mysql -u USER -p DATABASE < PATH/FILE.SQL.
WINDOWS “UNKNOWN COMMAND”
D:\http\>mysql -u root -p test < d:\http\test.sql
'mysql' is not recognized as an internal or external command,
operable program or batch file.For Windows users, if you get the “MySQL is not recognized” error, you will need to add the MySQL folder to the system path.

IMPORT SQL FILE WITH MYSQL WORKBENCH
If you are uncomfortable with the command line or have to manage multiple databases, Oracle offers a free management tool called MySQL Workbench.
DOWNLOAD & INSTALLATION
You can get the latest version of MySQL Workbench from the official MySQL website. Installation is very straightforward, just launch the installer and hit “next”.
HOW TO IMPORT WITH MYSQL WORKBENCH
ADD MYSQL CONNECTION
Launch MySQL Workbench. Add a connection to your database, then click on it.
SERVER > DATA IMPORT
After connecting to your database, Server > Data Import.
SELECT FILE > SELECT DATABASE > START IMPORT
Lastly, just choose the SQL file to import, and where to import it into.
PHPMYADMIN IMPORT SQL FILE
This final method is another tool that is made in PHP – If you have installed the XAMPP server, then you already have it.
DOWNLOAD & INSTALLATION
If you have installed the XAMPP server, simply access http://localhost/phpmyadmin. If not, you can also get the latest version of phpMyAdmin from their official website. There is no installation required, just unzip it into your “public HTML” folder.
HOW TO IMPORT WITH PHPMYADMIN
You can probably figure this one on your own… Select a database > Import > Choose File > Go.
UPLOAD FILE SIZE LIMIT
php.ini
upload_max_filesize = 100M
post_max_size = 100MPlease take note that phpMyAdmin is limited by the upload limit set in the php.ini file – You will want to avoid large SQL files, or at least zip them before uploading. Alternatively, you can change the limits in php.ini .
WHICH IS THE BEST METHOD?
Well, everyone has their preferences – Some prefer to not install anything and import SQL files in the command line, while a few like to use the Workbench to manage multiple databases at the same time. All 3 methods work fine, just test it out yourself and stick with the one you are most comfortable with.

Несмотря на то, что есть phpMyAdmin (и куча других помощников для работы с mysql), часто, для экспорта и импорта удобнее пользоваться консольными командами mysql. Процесс импорта экспорта происходит намного быстрее и нет необходимости заморачиваться с временем работы скрипта и размером файла (это актуально когда Ваш дамп базы достаточно большой).
Импорт данных в БД
Открываем консоль Windows (Win + R и вводим cmd).
Первый вариант импорта. Вводим команду в консоль:
mysql -u user_login -p user_pass db_name < path/to/file/dump_file_name.sql
где user_login — имя пользователя БД, user_pass — пароль пользователя, path/to/file/dump_file_name.sql — путь и имя файла содержащего дамп БД для импорта (Например: C:/my_file.sql).
Второй вариант импорта, вводим команду в консоль:
mysql -u user_login -p user_pass -h host_name
где user_login — имя пользователя БД, user_pass — пароль пользователя, host_name — имя хоста (обычно localhost).
Выбираем БД в которую необходимо импортировать:
use db_name
где db_name — имя БД в которую необходимо импортировать имеющийся дамп.
И импортируем командой:
source path/to/file/dump_file_name.sql
где path/to/file/dump_file_name.sql — путь и имя файла содержащего дамп БД для импорта (Например: C:/my_file.sql).
Экспорт данных из БД
Делаем экспорт посредством удобного mysqldump :
mysqldump -u user_login -p user_pass db_name > path/to/file/dump_file_name.sql
где user_login — имя пользователя БД, user_pass — пароль пользователя, path/to/file/dump_file_name.sql — путь и имя файла который будет содержать данные экспорта БД (Например: C:/my_file.sql).
Are you looking to import a MySQL database?
Whether you’re a beginner or an experienced professional, this guide will walk you through various methods to import your MySQL database efficiently.
We’ll cover everything from basic import techniques to advanced strategies, ensuring you have the knowledge to handle any import scenario.
MySQL Database Import: Understanding the Basics
What is a MySQL database import?
A MySQL database import is the process of loading data from an external source into a MySQL database. This can involve transferring entire databases, specific tables, or data sets from one MySQL server to another or from a backup file into a live database.
Why import databases in MySQL?
Importing databases in MySQL serves several purposes:
- Data migration: Moving data between different servers or environments
- Backup restoration: Recovering data from a previous backup
- Development and testing: Creating replicas of production databases for testing
- Data consolidation: Merging data from multiple sources into a single database
Common scenarios for database import
- Server upgrades or migrations
- Replicating production data in development environments
- Restoring data after system failures
- Transferring data between different database management systems
Key challenges in database import processes
- Ensuring data integrity during the transfer
- Managing large datasets efficiently
- Handling different character encodings and data formats
- Resolving conflicts with existing data or schema
Difference between MySQL import and restore
While both processes involve bringing data into a MySQL database, they differ in their purpose and execution:
- Import: Typically refers to bringing in new data or merging data from external sources. It may involve transforming or mapping data to fit the target schema.
- Restore: Specifically relates to recreating a database from a backup. It aims to return the database to a previous state exactly as it was when the backup was created.
Preparing for MySQL Database Import
Creating a backup of your existing database
Before importing new data, it’s crucial to back up your current database to prevent data loss. Use the following command:
mysqldump -u [username] -p [database_name] > backup.sql
Choosing the right import method for your needs
Consider these factors when selecting an import method:
- Data size: Command-line methods are often better for large datasets
- User interface preference: GUI tools like MySQL Workbench may be more user-friendly
- Technical expertise: Command-line methods require more MySQL knowledge
