Edit the config.inc.php file located in the phpmyadmin directory. In my case it is located at C:\wamp\apps\phpmyadmin3.2.0.1\config.inc.php
.
Find the line with $cfg['UploadDir']
on it and update it to $cfg['UploadDir'] = 'upload';
Then, create a directory called ‘upload’ within the phpmyadmin directory (for me, at C:\wamp\apps\phpmyadmin3.2.0.1\upload\
).
Then place the large SQL file that you are trying to import into the new upload
directory. Now when you go onto the db import page within phpmyadmin console you will notice a drop down present that wasn’t there before – it contains all of the sql files in the upload directory that you have just created. You can now select this and begin the import.
If you’re not using WAMP on Windows, then I’m sure you’ll be able to adapt this to your environment without too much trouble.
