数据包乱序。预计收到 1 个 6。数据包大小=26

Question

我使用 Lumen v7.0 和 MySQL v8.0.20 以及 Ubuntu 18.04.4 LTS

我在 SQL 中定义了一个存储过程，当我调用它时，出现以下错误：

数据包乱序。预计收到 1 个 6。数据包大小=26

这是连接驱动程序配置：

'mysql' => [
                'read' => [
                    'host' => [
                        env('DB_HOST')
                    ],
                ],
                'write' => [
                    'host' => [
                        env('DB_HOST'),
                    ],
                ],
                'driver' => 'mysql',
                'port' => env('DB_PORT', 3306),
                'database' => env('DB_DATABASE', 'forge'),
                'username' => env('DB_USERNAME', 'forge'),
                'password' => env('DB_PASSWORD', ''),
                'unix_socket' => env('DB_SOCKET', ''),
                'charset'   => 'utf8',
                'collation' => 'utf8_unicode_ci',
                'prefix' => env('DB_PREFIX', ''),
                'strict' => env('DB_STRICT_MODE', true),
                'engine' => env('DB_ENGINE', null),
            ],

这是我的代码：

function storedProcedureBalanceInMerchant($userId, $businessId)
    {
        try {
            $stmt = DB::connection('mysql')->getPdo()->prepare("CALL lending_ewallets_balance_in_merchant(?,?);");
            $stmt->execute([$userId, $businessId]);
            $pdoDataResults = [];
            do {
                $rowSet = $stmt->fetchAll(PDO::FETCH_ASSOC);
                array_push($pdoDataResults, $rowSet);
            } while ($stmt->nextRowset());

            return loanBnpl($pdoDataResults);
        } catch (Exception $exception) {
            dd($exception->getMessage());
            return ['loan' => collect([]), 'bnpl' => collect([])];
        }
    }

注意到，当我直接在 MySQL 中调用该存储过程（如

mysql> CALL lending_ewallets_balance_in_merchant(87,165);

）时，它会返回预期结果，不会出现错误。

我该如何解决这个问题？

此外，这是存储过程：

DELIMITER $$

  AND (ld.status = 'activated' OR ld.status = 'finished');

                " AND ", business_id_param, " IN(", query_string, ")",
                "GROUP BY ld.id, ld.type");

    PREPARE stmt FROM @qry;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
    
END LOOP loop_List;

Close user_dossiers;

Answer 1

尝试将

PDO::ATTR_EMULATE_PREPARES

设置为

true

'options' => [
    PDO::ATTR_EMULATE_PREPARES => true
]    

PDO 将模拟驱动程序的准备语句/绑定参数 本身并不支持他们

第二个错误可能来自

fetchAll()

$queryResult = DB::select('call lending_ewallets_balance_in_merchant(?, ?)', [$userId, $businessId]);
