依次在舊值旁邊添加一個新值，以逗號分隔

Question

我在列pushed_closed值“09:51”。

我需要在列中添加pushed_closed ，旁邊值“09:51”，值2，如：

09:51，09 : 54 （以逗號分隔）。

我的PHP代碼：

$connection = db_connect();
        $username = $_SESSION['username'];
        $ora_terminare = '09:54';
        mysqli_begin_transaction($connection);
        $query = mysqli_query($connection, "UPDATE birouri SET closed_program = 'DA', pushed_closed = '$ora_terminare' WHERE username = '$username'");
        mysqli_commit($connection);

如何創建正確的Mysqli查詢？

Answer 1

$connection = db_connect();
$username = $_SESSION['username'];
$ora_terminare = '09:54';
mysqli_begin_transaction($connection);
$query = mysqli_query($connection, "UPDATE birouri SET closed_program = 'DA', pushed_closed = concat(coalesce(pushed_closed, ''), ',', '$ora_terminare') WHERE username = '$username'");
mysqli_commit($connection);
