In some cases if you have a really large
.sql file, it is best to import it via the command line.
You might need to do this in case that you are using a tool like PHPmyAdmin, which more often than not, has a certain limit that the file that you want to import could be.
In this tutorial, you will learn how to import an
Before you get started you need to have MySQL installed and an
In case that you don't have an
.sql backup of your database, you can follow the steps here on how to do that:
Creating a blank database
What I usually prefer doing is to create a completely empty database, so that way I know that there will be no existing data or table structure which could cause issues during the import.
To create a new blank database, first access MySQL:
mysql -u your_user -p
And then you can use the following statement:Checkout our latest product - the ultimate tailwindcss page creator 🚀

Finally exit the MySQL prompt:
Note: make sure to change the
demo_dbwith the name of the database that you want to create.
.sql file to MySQL
Once you have your plain database in place, you can import your
.sql file using the following command:
mysql -h localhost -u username -p demo_db < your_exported_file.sql
Rundown of the command:
mysql: first we specify the MySQL client CLI tool
-h: this flag is used to specify the host that you want to import the data to. If you have your
.sqlfile stored on the same server where your MySQL service is running on, you can specify
localhostas the host, but if you are running your MySQL service on a remote server, make sure to change this accordingly.
-u: this flag specifies the MySQL username that you would like to use.
-p: this flag indicates that you should be prompted to enter a password once the command is executed.
demo_db: this is the name of the database that we've just created in the previous step
<: this symbol indicates that we want to import the
.sqlfile to the specified MySQL database
- finally we have the name of the
.sqlfile. Note that if the file is not in the same directory as your current directory, it is better to provide the full path to the
Once you run the command it might take a while for the operation to complete depending on the size of the file. You would not see any output while the operation is on going.
This is pretty much it! Now you know how to import a
.sql file to a MySQL database!
