Import Large MySQL Databases into PHPMyAdmin with BigDump.php

Mar 22 2011

When migrating a site that has been around for a while, I often run into the problem where my MySQL Database is just too large to import via the web interface of PHPMyAdmin. Often times its to a server that doesn’t allow remote access to their databases. What is a poor dev to do?

Take a big dump

Although this script has been around for almost 9 years, its still an essential tool for every developers toolbox. Big Dump staggers the database import so your server does not timeout. Here is a quick tutorial on how to use Big Dump.



  1. Download the latest version of Big Dump here.
  2. Open up bigdump.php and configure: Server, database name, username, password, and the file name.
  3. Upload both your SQL file and bigdump.php to your server
  4. Browse to bigdump.php and click import

Thats it! Wait a few minutes and you will see a confirmation screen similar to the one below. Make sure to delete bigdump.php off your server when you are finished.

    “MySQL: Column count doesn’t match value count at row 1 ”

  24. kdavid says:

    My database is 2Gbs, any ideas? keep geting this error however my sql dump file is already uploaded to the server.

    Can’t open daily.sql for import

    Please, check that your dump file name contains only alphanumerical characters, and rename it accordingly, for example: daily.sql.
    Or, specify $filename in bigdump.php with the full filename.
    Or, you have to upload the daily.sql to the server first.
