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 := \'\         


        

Answer 1

It's failing on ->fetchAll() because an UPDATE query does not return any rows/data.

What you want to do, is check out PDO::rowCount(). This returns the count of how many rows have been affected by your query.

echo $stmt->rowCount();
