I'm using PHP to send this query where lastConn
is a datetime
object.
$result = $mysqli->query("SELECT id, username, lastConn FROM users LIMIT $startIndex, 50") or die($mysqli->error);
However my goal is not to get the raw lastConn
data, but the time difference between lastConn
and CURRENT_TIMESTAMP
. I wrote this query which does the job :
SELECT TIMESTAMPDIFF(MINUTE,lastConn,CURRENT_TIMESTAMP) AS 'duration' FROM users;
I'm now trying to merge these two queries together to get the time difference in the first query but I can't seem to find the correct syntax.
Here is how I'm retrieving the data after performing the query using PHP:
while($row = $result->fetch_assoc()){
echo $row['id'];
echo $row['username'];
echo $row['lastConn']; //should echo the time difference instead of the raw lastConn value
}
How can I directly get the time difference between lastConn and CURRENT_TIMESTAMP in my first query, without having to use a second one ?
you could probably just add the portion of your second query to the first, like this below. you had it all working, just needed that last step!
$mysqli->query("SELECT id, username, lastConn, TIMESTAMPDIFF(MINUTE,lastConn,CURRENT_TIMESTAMP) AS 'duration' FROM users LIMIT $startIndex, 50")
hope this helps.
