Normally phpMyAdmin imports sql files with less than 3 MB. To upload .sql files with more than 3 MB (usually in wordpress site) we have to use a diffent method.
Move to phpMyAdmin folder usually it is located in “C:wampappsphpmyadmin3.3.9”.
Open config.inc.php file.
Find the code $cfg[‘UploadDir’] =”; and replace it with $cfg[‘UploadDir’] = ‘upload’;
Save config.inc.php file.
Create a folder named upload into the phpMyAdmin folder ( C:wampappsphpmyadmin3.3.9 ).
Copy your database file into the upload directory ( C:wampappsphpmyadmin3.3.9upload ).
Start WAMP Server then open phpMyAdmin and select any database. Click import option, now you can see a drop down box after web server upload directory option. Select the databse file in the drop down box and press go button.
