获取 Laravel 存储过程的结果

Question

我使用的是 Laravel 5.4 和 MySql 5.7、PHP 5.6。我正在尝试调用一个存储过程（执行 SELECT 查询，加入多个表），并将结果返回给我的 PHP。

以下是我尝试失败的事情：

PHP 1：

$result =  DB::select('CALL rentalsAvailables_get(?, ?, ?, ?)',
                array(
                    'p0' => Carbon::now(),
                    'p1' => Carbon::now()->addDays(7),
                    'p2' => 100,
                    'p3' => 2
                )
    );
return var_dump($result);

结果 1：

{
   "error": {
        "message": "SQLSTATE[HY000]: General error: 2031  (SQL: CALL rentalsAvailables_get(2017-03-11 16:00:42, 2017-03-18 16:00:42, 100, 2))",
        "code": "HY000",
        "status_code": 500
   }
}

PHP 2：

$result =  DB::select('CALL rentalsAvailables_get(:p0, :p1, :p2, :p3)',
                array(
                    'p0' => Carbon::now(),
                    'p1' => Carbon::now()->addDays(7),
                    'p2' => 100,
                    'p3' => 2
                )
    );
return var_dump($result);

结果 2：

array(0) {
}

** 存储过程：**

    DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `rentalsAvailables_get`(IN `startDate` DATETIME, IN `endDate` DATETIME, IN `maxPrice` INT(11) ZEROFILL, IN `capacity` INT(2))
    NO SQL
SELECT a.rentalId, a.rentalName, a.rentalBathroom, a.rentalBedroom, a.rentalCapacity, a.rentalCover, a.rentalLat, a.rentalLong, a.rentalLocation, a.rentalStatus, a.rentalSummary, a.rentalText, a.rentalOwnerId,
b.rentalTypeId, b.rentalTypeName,
c.id as 'userId', c.name,
d.rentalPriceId, d.rentalPrice

FROM rentals as a
INNER JOIN rentalTypes as b
ON a.rentalTypeId = b.rentalTypeId
INNER JOIN users as c
ON a.rentalOwnerId = c.id
INNER JOIN rentalprice as d
ON a.rentalId = d.rentalId

WHERE a.rentalCapacity > @p3
AND a.rentalStatus = true
AND d.rentalPrice < @p2
AND d.rentalPriceStartDate <= @p0
AND d.rentalPriceEndDate >= @p1
AND a.rentalId NOT IN (
        SELECT eSub.rentalId FROM unavailabilities as eSub WHERE eSub.unavailabilityStartDate >= @p0 AND eSub.unavailabilityEndDate <= @p1
    )
AND a.rentalId NOT IN (
        SELECT fSub.rentalId FROM rent as fSub WHERE fSub.rentStartDate >= @p0 AND fSub.rentEndDate <= @p1
    )$$
DELIMITER ;

笔记：

我当然已经检查过，并且在像这样调用它时从我的查询中得到了结果：

SET @p0='2017-03-11 04:26:09.000000';
SET @p1='2017-03-17 04:26:09.000000';
SET @p2='1000';
SET @p3='2';
CALL `rentalsAvailables_get`(@p0, @p1, @p2, @p3);

有没有人已经得到这个问题？谢谢阅读

Answer 1

你应该CALL your_procedure通过DB::raw到DB::SELECT.

所以这将起作用并返回结果集：

$p0 = Carbon::now();
$p1 = Carbon::now()->addDays(7);
$p2 = 100;
$p3 = 2;
DB::select(DB::raw("CALL rentalsAvailables_get($p0, $p1, $p2, $p3)"));

您也可以使用方法将结果集转换为Eloquent 模型hydrate。

Foo::hydrate($result_from_db_select);

希望这能在 6 个月后对您有所帮助:))
