Is Wordpress $wpdb->prepare necessary?

Question

SQL

Good afternoon, please tell me if I need to use $wpdb->prepare if I use $wpdb->insert update or others? Or is prepare embedded in them? I can't find the answer in the code.

Answer 1

Judging by the code, it is not necessary.
The last line of the method that is called from insert:

return $this->query( $this->prepare( $sql, $data ) );
