Insert CURRENT_TIMESTAMP with prepared statement

问题

I´m inserting data with prepared statements. How can I assign a variable to CURRENT_TIMESTAMP and bind the value?

I have a database table with the columns "name, lastfed, lastdoc and id". The 2 columns called lastfed and lastdoc are of type timestamp. I have a function and once I run it I want lastfed and lastdoc to register the current date and time.

$lastfed = CURRENT_TIMESTAMP;
$lastdoc = CURRENT_TIMESTAMP;

$query = $db->prepare("INSERT INTO test (`name`, `lastfed`, `lastdoc`, `id`) VALUES (?, ?, ?, ?)");

$query->bindValue(1, $name);
$query->bindValue(2, $lastfed);
$query->bindValue(3, $lastdoc);
$query->bindValue(4, $user);

回答1:

INSERT INTO test (`name`, `lastfed`, `lastdoc`, `id`) 
VALUES (?, CURRENT_TIMESTAMP, CURRENT_TIMESTAMP, ?)

Or you set CURRENT_TIMESTAMP as default to these columns DB wise. Then you can leave them from your insert statement:

INSERT INTO test (`name`, `id`) 
VALUES (?, ?)
