cannot import too large sql file to mysql

Question

I have a 28 MB sql file need to import to mysql. Firstly, i'm using xampp to import, and it fails, and so i change my max_file_uploads, post_size(something like that)in php.ini-development and php.ini-product to 40 MB, but it still show "max:2048kb" and import fail again.

From research, i've learned to import by using mysql.exe, so i open mysql.exe and type the command line(msdos) below:

-u root -p dbname < C:\xxx\xxx\sqlfile.sql

but still failed again and again.....

what the problem is? xampp? or my sql setting?

Answer 1

Try this:

mysql -uroot -p --max_allowed_packet=24M dbname

Once you log into the database:

source C:\xxx\xxx\sqlfile.sql

I think that you should be able to load your file

Answer 2

How large is your file?. You might as well do it from a console:

mysql -u##USER## -p ##YOUR_DATABASE## < ##PATH_TO_YOUR_FILE##

Do that without executing your mysql.ext file: just "cd" right into the directory and try the command.

It will ask for your password and start importing right away. Don't forget to create the database or delete all tables if it's already there.

I always found this approach quick, painless and easier that rolling around with php directives, phpmyadmin configuration or external applications. It's right there, built into the mysql core.

Answer 3

You should increase max_allowed_packet in MySQL.

Just execute this command before importing your file:

set global max_allowed_packet=1000000000;

Answer 4

I also fetched the similar problem. So after that I also conclude , large sql file will never be imported to mysql. It will always give timeout error.

Then I found a solution.

There is an software Heidisql .

follow below steps:-

1) download the software.
2) then install the software
3) create new session in Heidisql and open the session
4) then go to Tools -> Load SQL File -> Browse. 

That's it. This solution works best for me.
