控制器返回空值

Question

I have a service file where I'm running a stored procedure:

    function createCampaign($campaignName, $groupNumber){

    $stmt = \DB::connection('odbc')->getPdo()->prepare('CALL SCHEMA.INSERT_CAMPAIGN(?,?,?)');

    $stmt->bindValue(1,$campaignName, PDO::PARAM_STR);
    $stmt->bindValue(2,$groupNumber, $groupNumber==0 ? PDO::PARAM_NULL : PDO::PARAM_INT);
    $stmt->bindParam(3,$out2, PDO::PARAM_INT);

    $stmt->execute();

    return $out2;

}

When I run this stored procedure, the third parameter is giving back OUT_CAMPAIGN_ID and the expected ID, so this works. I'm returning that output variable with $out2

My controller, which calls the previous function and also expects the return back:

 public function createCampaign(Request $request)
{
    $campaignName = $request->campaignName;
    $groupNumber = $request->groupNumber;

    $campaignService = new CampaignService();
    $createCampaign = $campaignService->createCampaign($campaignName, (int) $groupNumber);

    return Response::json(["OUT_CAMPAIGN_ID" => $createCampaign]);
}

However, when I console log data.OUT_CAMPAIGN_ID in my blade, or even console log data it just gives me OUT_CAMPAIGN_ID:null

Am I doing something wrong in the way I expect it back in the controller?

Stored procedure:

BEGIN

INSERT INTO SCHEMA.TABLE(NAME,NUMBER)
VALUES (IN_NAME, IN_NUMBER);

SET OUT_ID = IDENTITY_VAL_LOCAL();

END;

It sounds like your stored procedure returns a value? I think what you need to do is more like:

$stmt = \DB::connection('odbc')->getPdo()->prepare('CALL SCHEMA.INSERT_CAMPAIGN(?,?,?)');
$stmt->bindValue(1,$campaignName, PDO::PARAM_STR);
$stmt->bindValue(2,$groupNumber, $groupNumber==0 ? PDO::PARAM_NULL : PDO::PARAM_INT);
$stmt->bindParam(3, $out2, PDO::PARAM_INT|PDO::PARAM_INPUT_OUTPUT);
$stmt->execute();
