主义的findOneBy simple_array属性未返回有效匹配项

Question

I have an entity LongBeachClickerUploadBallotOption that contains a simple_array property $publicComments:

/**
 * @var array
 * @ORM\Column(name="public_comments", type="simple_array", nullable=true)
 */
protected $publicComments;

When I instantiate a new object and give it multiple publicComments, and then try to query for that object, doctrine does not seem to return a match:

$lbBallotOption = new LongBeachClickerUploadBallotOption('AMPC', array('1', '2', '3'));
$this->em->persist($lbBallotOption);
$this->em->flush();

dump($lbBallotOption->getPublicComments());

$bo = $this->em->getRepository('VoteBundle:LongBeachClickerUploadBallotOption')
    ->findOneBy(array('motion' => 'AMPC', 'publicComments' => array('1', '2', '3')));

dump($bo);

$bo = $this->em->getRepository('VoteBundle:LongBeachClickerUploadBallotOption')
    ->findOneBy(array('motion' => 'AMPC', 'publicComments' => array(1, 2, 3)));

dump($bo);
exit;

This code outputs the following:

HearingVoteImport.php on line 258:
array:3 [▼
  0 => "1"
  1 => "2"
  2 => "3"
]
HearingVoteImport.php on line 263:
null
HearingVoteImport.php on line 268:
null

What's going on here? I tried querying both with integer "strings" and true ints just out of curiosity.

According to Doctrine's SimpleArrayType, it should implode these values with a ',' and then I would assume just do a string match... The rows in the database I can see are storing properly:

id    motion   public_comments
109   AMPC     1,2,3

Edit: I added SQL Logging:

$this->em->getConnection()->getConfiguration()->setSQLLogger(new \Doctrine\DBAL\Logging\EchoSQLLogger());

and it outputs the following:

  SELECT t0.id AS id1, 
  t0.motion AS motion2, 
  t0.public_comments AS public_comments3 
  FROM lb_clicker_upload_ballot_option t0 
  WHERE t0.motion = ? AND t0.public_comments IN (?) LIMIT 1 
  array(2) { [0]=> string(4) "AMPC" [1]=> array(3) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(1) "3" } } 
  array(2) { [0]=> string(6) "string" [1]=> int(102) }

And of course, as mentioned in the first response, I tried querying like this:

$bo = $this->em->getRepository('VoteBundle:LongBeachClickerUploadBallotOption')
        ->findOneBy(array('motion' => 'AMPC', 'publicComments' => "1,2,3"));

only for it to complain:

Warning: implode(): Invalid arguments passed

Answer 1

AFAIK, you have to query array fields like a standard text field . So imloding an array is an easiest way to go.

Answer 2

I know the question is quite old, but since I stumbled across the same issue... The SQL Logging was quite helpful.

The problem is, that in public_comments a string of comma separated strings is stored in the database. This string has to be found in the array given to the IN keyword. Since in this array the values are separate and not concatenated to a string as in public_comments the IN operator can't find the string.

I circumvented the issue by preparing the $search array as

$public_comments = array(1, 2, 3);
$search = array(implode(',', $public_comments));

$repo = $this->em->getRepository('VoteBundle:LongBeachClickerUploadBallotOption');

$bo = $repo->findOneBy(array('motion' => 'AMPC', 'publicComments' => $search));

The wrapping array() is needed to avoid the observed complaints about the invalid arguments in implode. I'd say it's a bug in handling of simple_array in a search context.
