PHP, MySQL, PDO - Get result from UPDATE query?

Question

I am updating a row in a table, and trying to return the updated row, as per this SO answer.

My code is the following:

$sql = \"SET @update_id := \'\

You're right about getting the exception SQLSTATE[HY000] for $stmt->rowCount();

The problem is, you cannot fetch an UPDATE query because these queries simply don't return values. To circumvent this, use rowCount().

As written in the PHP documentation, PDOStatement::rowCount() returns the number of rows affected by a DELETE, INSERT, or UPDATE statement.

Check out this example.

prepare('UPDATE ... PICNIC');
$update->execute();

/* Return the number of rows affected */
   echo $updateCount = $update->rowCount();
