Answer 1

Use this from mysql command window:

mysql> use db_name;
mysql> source backup-file.sql;

Answer 2

3 things you have to do, if you are doing it locally:

in php.ini or php.cfg of your php installation

post_max_size=500M

upload_max_filesize=500M

memory_limit=900M

or set other values. Restart Apache.

OR

Use php big dump tool its best ever i have seen. its free and opensource

Answer 3

I really like the BigDump to do it. It's a very simple PHP file that you edit and send with your huge file through SSH or FTP. Run and wait! It's very easy to configure character encoding, comes UTF-8 by default.

Answer 4

Had a similar problem, but in Windows. I was trying to figure out how to open a large MySql sql file in Windows, and these are the steps I had to take:

• Go to the download website (http://dev.mysql.com/downloads/).
• Download the MySQL Community Server and install it (select the developer or full install, so it will install client and server tools).
• Open MySql Command Line Client from the Start menu.
• Enter your password used in install.

• In the prompt, mysql>, enter:

  CREATE DATABASE database_name;

  USE database_name;

  SOURCE myfile.sql

That should import your large file.

Answer 5

Since you state (in a clarification comment to another person's answer) that you are using MySQL Workbench, you could try using the "sql script" option there. This will avoid the need to use the commandline (although I agree with the other answer that it's good to climb up on that horse and learn to ride).

1. In MySQL Workbench, go to File menu, then select "open script". This is probably going to take a long time and might even crash the app since it's not made to open things that are as big as what you describe.

2. The better way is to use the commandline. Make sure you have MySQL client installed on your machine. This means the actual MySQL (not Workbench GUI or PhpMyAdmin or anything like that). Here is a link describing the command-line tool. Once you have that downloaded and installed, open a terminal window on your machine, and you have two choices for slurping data from your file system (such as in a backup file) up into your target database. One is to use 'source' command and the other is to use the < redirection operator.

Option 1: from the directory where your backup file is:

$mysql -u username -p -h hostname databasename < backupfile.sql

Option 2: from the directory where your backup file is:

$mysql -u username -p -h hostname
[enter your password]
> use databasename;
> source backupfile.sql

Obviously, both of these options require that you have a backup file that is SQL.

Answer 6

I believe the easiest way is to upload the file using MYSQL command line.

using the command from the terminal to access MySQL command line and run source

    mysql --host=hostname -uuser -ppassword
    source filename.sql 

or directly from the terminal

   mysql --host=hostname -uuser -ppassword < filename.sql

at the prompt

I found this link How to upload big sql dump files (memory, HTTP or timeout problems) in MYSQL. it give the outline of what to do to upload a large SQL. It helped me when I got face with a client 196mb sql dump. Something the PHPMySql couldn't handle.
