TLDR

Quickest way, right? Here you go:

mysql -u username -p database_name < file.sql

Input your MySQL username, the intended database_name and your file.sql path. You'll be prompted for your password. This magic line will stream the content of file.sql into database_name, efficient for big data size.

Keep it simple, keep it safe!

Who needs over-complication when the direct import method brings simplicity and reliability together. Lower chance of circus surprises (errors, in common language) and a prized gem when dealing with big SQL files. You are having a smooth ride with a straight straightforward data transfer adventure.

Check, double-check, and hey, check again

Hold on, cowboy! Before you means-business .sql gets in, confirm if it's getting along with your MySQL version. Check and recheck for integrity, as a corrupted or incomplete file will throw pies at your face (meaning unexpected errors and incomplete data restore).

Getting authorities onboard

Let's get our permissions right. The MySQL server needs to have read access to file's location. Your database user should have the necessary permissions to do the dance, pardon, the data imports. Getting familiar with MySQL permission system is a good homework, helps to avoid the "access denied" party.

Taking one step at a time with MySQL Console

Preferring to be cautious? Use the source command inside MySQL console for a walkthrough. Do remember to select the correct database with:

mysql> use DATABASE_NAME; # Identify yourself to DB, it's polite.

Next, call the file with:

mysql> source path/to/file.sql; # And the party begins!

You'd love this, errors won't stop the process. So, you can take a bow for completion and come back for debugging.

Walking the path as per the OS

Using the correct slashes in file paths is pure gold!

mysql> source C:/path/to/file.sql; or mysql> source C:\\path\\to\\file.sql; # Yes, you can!

Handling the heavyweights

Big SQL file? Coffee is on me if you're copying it to the root of your C:\ drive for easier access. You can also split large files into smaller ones. Imagine a SQL file buffet!

Dodge ball, dodge errors

Command-line users, you are up for a treat. Errors and line numbers are displayed for your debugging pleasures. MySQL console users, put your Sherlock hat on, as errors may need you to scan the logs for detailed minor culprits.
