MySQL Import a large database file method

MySQL Import a large database tutorial file method

File Size 800MB

Method One

The above document generally means that, when you encounter a large import file, first check the PHP tutorial. ini configuration file in the following three places, Upload_max_filesize, Memory_limit and Post_max_size, and recommended that the modified value slightly larger than the import of the huge SQL database files; According to this prompt, I modified the above three values in php.ini, restart the PHP environment, import again, although phpMyAdmin still show the import maximum limit: 20,480 KB, However, the huge 80M database files have been successfully imported.
The phpMyAdmin version is 2.8.1, Environment: Apmserv 5.1.2

Method Two
Some people say that the php.ini file configuration of the post_max_size change than you want to import a larger database file, such as now I want to import the database file is 487MB, then you can change this to: 700MB, Then use the phpMyAdmin tool's import function to implement, but I tried this method does not work, and then with experienced friends, tell, use the MySQL tutorial command-line mode, practice is as follows, the detailed steps are as follows:

1. First point the lower left corner of the computer "start"-----"Run" in the box input "cmd" into the command line mode;

2. The following interface appears:
Microsoft Windows XP [version 5.1.2600]

C:documents and Settingszxchai>
My PHP-Installed suite XAMPP, it integrates (Apache+mysql+php+perl)
is a powerful build station tutorial integrated software package, in short is into your MySQL installation directory, my MySQL installed in e:xamppmysql this directory, and then in the command line mode (that is, black screen) input command:
Microsoft Windows XP [version 5.1.2600]

C:documents and Settingszxchai>e:

E:>CD Xamppmysqlbin

E:xamppmysqlbin>mysql-u root–p

Again, the uplink root is my MySQL username, the command line appears with a prompt:

Enter Password:

Then enter your MySQL password later:

Enter Password: * * *

Then, when you enter, a prompt will appear:

Welcome to MySQL Monitor. Commands End With; or G.

Your MySQL Connection ID is 1

Server version:5.1.41 Source Distribution

Type ' help, ' or ' h ' for help. Type ' C ' to clear the current input statement.

Mysql>
At this point is to prompt you that the database is ready to try, and then enter the database you want to use after mysql>, for example, I have an empty database in my MySQL named TestDB, and then I input use testdb behind mysql>;

That is:mysql> use TestDB;

And then hit enter, and it will appear:

Database changed

Mysql>

Then enter your MySQL database file, such as your MySQL file is in the D:test.sql

So at this point you should enter source D:test.sql as follows:
Database changed

Mysql>source D:test.sql

And then you hit the car and there are a lot of them:
Query OK, 0 rows Affected (0.00 sec)

Query ok,5000 rows Affected (1.55 sec)
Until the last appearance:
Mysql>
Your large database file has been successfully imported into the MySQL database

Example Three
