I would like to count how many hours are between this two formats using laravel query builder.. how could I do that? I would like to know if it exists a way to transform my first format which is varchar into a Timestamp format.
Utilizing STR_TO_DATE
function to parse your format, i got the following working in MySql.
->select(DB::raw("TIMESTAMPDIFF(HOUR, updated_at, STR_TO_DATE(fetch_tope, '%d/%m/%Y %h:%i:%s')) as hours"))
