我如何才能从MySQL过程中获取LARAVEL端的数据

在使用MySQL 8的Laravel 8站点上，我创建了一个带有1个in和2个out参数的过程:

DELIMITER $$

DROP PROCEDURE IF EXISTS getObjectsCount $$

CREATE DEFINER=`lardev`@`localhost` PROCEDURE `getObjectsCount`( IN in_objectType varchar(100), OUT retCount bigint unsigned, OUT totalUsersCount bigint unsigned  )
BEGIN


IF in_objectType = 'users_without_active_tasks' THEN
    select count(*) into retCount from users where users.id not in (select distinct tasks.creator_id from tasks where tasks.status = 'T');
END IF;

IF in_objectType = 'users_without_completed_tasks' THEN
    select count(*) into retCount from users where users.id not in (select distinct tasks.creator_id from tasks where tasks.status = 'D');
END IF;

SELECT concat('retCount is ', retCount);
select count(*) into totalUsersCount from users;


END$$
DELIMITER ;

并将其命名为:

call getObjectsCount('users_without_completed_tasks', @returnCount, @totalUsersCount);
select @returnCount, @totalUsersCount;

我得到了有效的结果.

但当我试图从php页面运行相同的过程时，如下所示:

$data = DB::select("call getObjectsCount('users_without_completed_tasks', @returnCount, @totalUsersCount)");
dd($data);

我得到了奇怪的结果:

+"concat('in_objectType is ', in_objectType)": "in_objectType is users_without_completed_tasks"

看起来该方法在服务器上不起作用.

我可以通过什么方式从MySQL过程中获取幼年期的数据？

"laravel/framework": "^10.34.2"
Mysql 8.0.34-0ubuntu0.22.04.1

提前谢谢！
