How do I solve &#General Error in MySQL (XAMPP):

During database development, MySQL errors occur from time to time. Recently, I encountered a headache "General error: 1813" error while using MySQL in XAMPP environment, which prompts "Table creation failed: incorrect database definition or file corruption". After troubleshooting, I found a solution and share my experience here.

Question: General error: 1813

The error occurs when I am using Laravel 11 to migrate the database. Strangely, the same migration operation runs fine in other environments, which makes me suspect the problem is in my local XAMPP environment.

Troubleshooting steps

1. Migrate file check: I first checked for syntax errors or compatibility issues with the migration file, but everything worked fine.
2. MySQL Data Directory Check: I checked XAMPP's MySQL data directory (for example: c:\xampp\mysql\data\project_name ) to find any residual files related to the table to be created.
3. Database permission check: I confirm that my user has sufficient database permissions.

Solution

Eventually, I found that the problem was the residual .ibd file in the MySQL data directory. The solution is as follows:

1. Problem file identification: The error is because I manually deleted a table before, but the corresponding .ibd file still exists in the data directory.
2. .ibd file location: I found a file named tablename.ibd in c:\xampp\mysql\data\project_name directory ( tablename is the name of the deleted table).
3. .ibd file deletion: I deleted the tablename.ibd file directly.
4. MySQL restart: After deleting the file, I restarted the MySQL service through the XAMPP control panel.
5. Migration retry: Run the Laravel migration again, this time it succeeded, no errors.

Experience summary

This experience taught me:

• When manually deleting MySQL tables, be sure to clean up all residual files.
• Understanding MySQL's data storage and table file management mechanisms is crucial for troubleshooting.
• Back up the database regularly, especially before performing manual operations.
