Orphan data are those information which are the but not used. It does not have links or parents. It may be those data that are left by plugin or posts.

This data is present in wp_postmeta table. You can use the below query to delete these data.

DELETE FROM wp_postmeta WHERE meta_key = ‘meta-key-to-delete’;

Use the above query with your own meta-key value and the query will delete all its data related to  that meta key.
