  2   IpAddressesTableSeeder::run()
      C:\Users\user\Desktop\laravel-vue-polling-app\vendor\laravel\framework\src\Illuminate\Container\BoundMethod.php:29

and here is the seeder file

<?php

use Illuminate\Database\Seeder;

class IpAddressesTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $ipsPath = storage_path('ips.csv');
        $pdo = \DB::connection()->getPdo();
        $pdo->exec("
            LOAD DATA LOCAL
                INFILE '" . $ipsPath . "'
            INTO TABLE
                `ip_addresses`
            FIELDS TERMINATED BY ','
            ENCLOSED BY '\"'
            LINES TERMINATED BY '\r\n'
            IGNORE 0 LINES;
        ");
    }
}

None of the files have been altered by me and is as is in the repo as far as i know

Answer 1

Windows uses \\ for the path separator, which is also the escape character in MySQL. When you pass C:\\Users\\user\\Desktop\\laravel-vue-polling-app\\storage\\ips.csv to MySQL, it thinks the single \\ is the escape character, not the path separator. To fix this, do

$ipsPath = addslashes($ipsPath);

before you use it in your query.

Answer 2

As you can see

PDOException : SQLSTATE[HY000]: General error: 7890 Can't find file ' C:UsersuserDesktoplaravel-vue-polling-appstorageips.csv '. no directory separators ?

did you try to use [ESCAPED BY 'char']

Your seeder file $ips should be like

$ipsPath = addslashes(storage_path('ips.csv'));
...
