使用 PHP 在 Mysql 表中切换状态 - 最简单的方法

Question

I have a Mysqli table called status with the columns ID, STATUS.

The STATUS can be 1 or 2 only.

I want to update the STATUS column the easiest way, so if the STATUS value is 1, update it to 2 and vice versa.

Normally I can do it like:

 $c=$mysqli->query('SELECT * FROM status WHERE id="1"' );
    $kats=$c->fetch_assoc();
    $status=$kats['status'];

if ($status == '1') {$newstatus = '2';} else {$newstatus = '1';}

$mysqli->query("UPDATE status SET status = '$newstatus' WHERE id=1" );

This will work, but is there an easier way, or maybe 1 row query for this? As the values are just changing from 1 to 2 or from 2 to 1 in one column.

Answer 1

If you only have two values then consider using a Boolean data type. If you do then you can do it in one query, something like this:

UPDATE status SET STATUS = !STATUS WHERE ID = ?

Also, it's kinda confusing having status as both a table and column name.
