[FIXED] Where is the post featured image link stored in the WordPress database?

Issue

Where is the featured image link stored in the WordPress Database? I searched in the wp_postmeta table but I cannot find out the exact post_id and links.

Is this correct? Could anyone please explain to me how it works?

Solution

The featured image ID is stored in wp_postmeta with a meta_key called _thumbnail_id. Example:

╔═════════╦═════════╦═══════════════╦═══════════╗
║ meta_id ║ post_id ║ meta_key      ║ meta_value║
╠═════════╬═════════╬═══════════════╬═══════════╣
║ 200     ║ 4       ║ _thumbnail_id ║ 48        ║
╚═════════╩═════════╩═══════════════╩═══════════╝

The actual thumbnail link is then contained in wp_posts with a post_type of attachment. Example:

╔════╦════════════╦═════════════════════════════════════════════════════╗
║ ID ║ post_type  ║ guid                                                ║
╠════╬════════════╬═════════════════════════════════════════════════════╣
║ 48 ║ attachment ║ http://example.com/wp-content/uploads/yourimage.png ║
╚════╩════════════╩═════════════════════════════════════════════════════╝
