I am trying to get the data of the current date in MySQL. I have a column named
created_at which stores the date and time
(2017-12-31 11:32:54)using the
NOW() function using the statements,
$stmt = $this->conn->prepare("INSERT INTO log(id, name, created_at) VALUES(?, ?, NOW())"); $stmt->bind_param("ss", $id, $name); $result = $stmt->execute();
Now I want to ignore the time in the
created_at column and retrieve the data of the current date (today’s date).
I tried using this query,
SELECT * FROM log WHERE created_at = DATE_SUB(CURDATE(), INTERVAL 0 DAY)
But this results in
zero rows selected.
Please help me solve this issue.
One option would be to wrap
DATE(), and then compare to
SELECT * FROM log WHERE DATE(created_at) = CURDATE();
But this has the drawback of precluding the possibility of using an index on the
created_at column. We could also phrase this as follows:
SELECT * FROM log WHERE created_at >= CURDATE() AND created_at < CURDATE() + INTERVAL 1 DAY;
This would allow an index to be used on
created_at, though it is a bit more verbose.
this will also work
SELECT * FROM log WHERE DATE(created_at, '%Y-%m-%d') = CURDATE();
