1. Identifying the Issues

The initial step in rectifying these errors involves recognizing the problem types:

  • Corrupted database table errors: These generally appear as a daunting text in a red box indicating issues such as auto-increment, primary key error, duplicate entries, or duplicate tables.

2. Recommended Fixes

Once the errors have been identified, implement the following strategies for rectification:

a. Export in GZIP Compressed Format

Exporting the data in a compressed format reduces its size and simplifies its import. During the export, select the custom option then pick 'gzipped' from the compression drop-down menu. This choice reduces possible friction during the import process and minimizes the probability of errors.

b. Adjust PHP Settings

Transforming your PHP settings may alleviate some import problems. Increase the 'max_upload_size,' 'max_execution_time,' and 'max_input_time' in your server settings or 'php.ini' file to grant PHP more scope and time to execute the upload.

c. Use Command Line for Import

In this scenario, use MySQL shell to import the data. First, navigate to the directory with the SQL file. Use a command similar to 'mysqldump -u dbuser -p dbname > dbfile.sql' to import your database.

d. Consider Outsourcing

When the problems resist your attempts to fix them personally, you can consider hiring another developer to run manual SQL fixes.
