How to Create a New MySQL User with Full Privileges

if database_url.startswith("postgres://"):
    database_url = database_url.replace("postgres://", "postgresql+psycopg2://")

This code ensures that:

<?php
// Load WordPress environment
require_once('/path/to/your/wp-load.php');

// Get all posts (any post type)
$args = array(
    'post_type'      => 'any', // 'any' retrieves all post types (posts, pages, custom post types)
    'post_status'    => 'any', // 'any' retrieves all post statuses
    'posts_per_page' => -1,    // Retrieve all posts
);

$all_posts = get_posts($args);

foreach ($all_posts as $post) {
    // Get the post ID
    $post_id = $post->ID;

    // Check if the post has attachments (media files)
    $attachments = get_attached_media('', $post_id);

    // Delete each attachment associated with the post
    foreach ($attachments as $attachment) {
        $attachment_id = $attachment->ID;
        // This deletes the file from the uploads directory and the database record
        wp_delete_attachment($attachment_id, true);
    }

    // Delete the post itself
    wp_delete_post($post_id, true); // true = force delete, bypass trash
}

echo 'All posts and their uploads have been deleted.';

• Backup: Make sure you have a backup of your database and uploads folder before running this script.
• Use on a staging site: Test it on a staging environment before running on a live site, as it will permanently delete all posts and their uploads.

MySQL sometimes uses temporary tables to perform sorts. If these temporary tables are disk-based (due to memory limits), performance can suffer. You can adjust the tmp_table_size and max_heap_table_size variables to allow MySQL to use larger in-memory tables.

Let’s start by creating a table that includes a JSON column.

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    preferences JSON
);

   Schema::create('tags', function (Blueprint $table) {
       $table->id();
       $table->string('name');
       $table->timestamps();
   });

In create_post_tag_table.php:

This MySQL cheatsheet provides a comprehensive overview of the most commonly used MySQL commands, complete with examples to help you quickly find the information you need. Whether you're creating and managing databases, writing queries, or handling transactions, this guide serves as a quick reference to help you work more efficiently with MySQL.

Step 1: Back Up the Tables

mysqldump -u root -p my_database users orders > backup_users_orders.sql

• Vite: Vite comes with a simpler configuration out of the box. It’s opinionated, meaning it has built-in best practices and defaults, making it easier to get started with.
• Webpack: Webpack is highly configurable and can be customized extensively, but this flexibility often comes with a steeper learning curve and more complex configuration files.

• Vite: Vite handles modern JavaScript features natively, leveraging the browser’s capabilities during development and optimizing for production only when needed.
• Webpack: Webpack can bundle any kind of asset (JavaScript, CSS, images, etc.) and provides advanced features like code splitting, tree shaking, and asset management, but these can add complexity to the build process.

     mutation {
       addBook(title: "1984", author: "George Orwell") {
         title
         author
       }
     }

• Flexible Queries: Allows clients to request only the data they need, reducing over-fetching.
• Strongly Typed: Ensures data consistency and helps with error handling.
• Single Endpoint: All data operations occur through a single endpoint, simplifying network requests.
