Question

I need to do something that seems to be very simple:

$bdd->query('UPDATE mytable SET aaa = \''.$aaa.'\', bbb = \''.$bbb.'\' WHERE name = \''.$name.'\'');

My problem: I have multiple records that match this “WHERE”, and I want to update only the most recent one (I have a date and an id that can be used to define which record is the most recent)

How can I change my WHERE to add something like “AND id = the_highest_id_of_this_query“?

Answer 1

You can limit to update only the most recent record

UPDATE your_table
SET some_column = 1
order by date_time_column desc
limit 1

where date_time_column can be any column indicating the order of the records. It could be an auto-increment ID too.
