Question

If I have this code (which is from their docs)

$query = DB::query(Database::SELECT, 'SELECT * FROM users WHERE username = :user');
$query->param(':user', 'john');
$query->execute();

How would I access the actual data returned from this?

I am looking for an associate array containing $array['username'] and whatever other columns are on the users table.

I have tried:

#1
echo $query->execute();
#2
$row = $query->execute();
echo $row['username'];
#3
$query->fetch();

None of which work. What am I missing?

Database_Result object is a wrapper for database row list. Usually it is used with foreach:

$rows = DB::query(Database::SELECT, 'SELECT * FROM users WHERE username = :user')
   ->param(':user', 'john')->execute();
foreach($rows as $row)
   echo $row['id'].': '.$row['username'];

If you are expecting only one row (its your question as I understand), use current():

$row = current($rows);
echo $row['username'];

Note that Database_Result can be used as a simple array, so current(), foreach(), count() and other array functions are available.

PS. Here is a link for kohana 2.3 docs, using DB Queries is the same.
