Importing Large Databases into phpMyAdmin: Troubleshooting File Size Issues

Encountering an error message stating "You probably tried to upload too large file" when attempting to import a large database through phpMyAdmin can be frustrating. This error typically occurs when the database file size exceeds the default upload limit. To resolve this issue and import large databases successfully, follow these steps:

Firstly, modify the php.ini configuration file:

1. Navigate to the php.ini file located at C:wampbinapacheApache2.4.4bin.

2. Adjust the following settings:

   • max_execution_time = 259200
   • max_input_time = 259200
   • memory_limit = 1000M
   • upload_max_filesize = 750M
   • post_max_size = 750M
3. Restart the WAMP server or all services.

If the issue persists, proceed to the next step:

1. Open config.default.php located at c:wampappsphpmyadmin4.0.4libraries (update the path according to your phpMyAdmin version).
2. Locate the $cfg['ExecTimeLimit'] = 300; line and modify it to $cfg['ExecTimeLimit'] = 0;.
3. Attempt to import the database again.

Loading Large Databases Using MySQL Console

An alternative approach is to load large databases using the MySQL Console:

1. Launch the MySQL Console from the WAMPServer Icon.
2. Enter the database password (e.g., root).
3. Select the target database using the command: USE DATABASENAME.
4. Load the SQL file with the command: SOURCE C:FOLDERdatabase.sql.
5. Press Enter to import the data.

Additional Considerations

Note that you cannot load compressed database files (e.g., .zip or .gz) directly. You must first extract the contents of the compressed file. Failure to do so will result in the MySQL Console crashing.
