Database Development Tutorials, Guides & Insights

• MySQL treats connections from localhost (via Unix socket) and 127.0.0.1 (via TCP/IP) as distinct connections. By default, the root user may only have privileges for localhost, causing an "Access Denied" error when trying to connect from 127.0.0.1.

This tutorial explains how to grant privileges to the MySQL root user for connections over TCP/IP (127.0.0.1). By following these steps, you can resolve access denied errors and ensure smooth connections to your MySQL database for both local development and remote applications.

   exit;

Open the MySQL configuration file again:

SELECT JSON_UNQUOTE(JSON_EXTRACT(preferences, '$.theme')) AS theme
FROM users
WHERE JSON_CONTAINS_PATH(preferences, 'one', '$.theme');

This query extracts the theme key, removes the quotes, and ensures the key exists.

• Create a New Factory

  php artisan make:factory FactoryName

Combine tables to reduce joins in read-heavy systems. Use with care.

Split large tables for better targeting and faster reads.
