how to do LOAD DATA LOCAL INFILE in laravel 5.4 - laravel-5.4

Question

i need to convert the following query in laravel 5.4
$loadDataToTempTableSql = "LOAD DATA LOCAL INFILE '".$filename."' INTO TABLE ABC FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\r' IGNORE 1 LINES";
$loadDataToTempTableRes = mysqli_query($link,$loadDataToTempTableSql);
$loadedData = mysqli_affected_rows($link);
what i did
Step1:
DB::select($load_data_to_temp_table_sql);
which is throwing exception:
SQLSTATE[HY000]: General error: 2014 Cannot execute queries while
other unbuffered queries are active. Consider using
PDOStatement::fetchAll(). Alternatively, if your code is only ever
going to run against mysql, you may enable query buffering by setting
the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. (SQL: LOAD DATA
LOCAL INFILE
'/Library/WebServer/Documents/public/abc
copy.csv' INTO TABLE ABC FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '
' IGNORE 1 LINES)
Step2:
$pdo = DB::connection()->getPdo();
$pdo->exec($load_data_to_temp_table_sql);
again exception:
PDO::exec(): LOAD DATA LOCAL INFILE forbidden
Please guide, what to do?

Answer 1

I have faced same kind of problems and after googling it has been solved now. You should add the following to your mysql/my.cnf file:
[Server]
local_infile=true
After that add 'options' => array(PDO::MYSQL_ATTR_LOCAL_INFILE => true) into your project's config/database.php file.
Now restart your MySQL from cmd/terminal. It will be fine to run the LOAD DATA LOCAL INFILE. If you still face a problem, you can visit https://tenerant.com/blog/using-load-data-local-infile-in-a-laravel-migration/.

i didn't work out with DB. i worked out with PDO and then i had to make a addition to MYSQL_ATTR_LOCAL_INFILE to the database.php file in config folder
'options' => [PDO::MYSQL_ATTR_LOCAL_INFILE => true],

Here is step by step your solution:
Goto/Open config file config/database.php
On connections => mysql array add following lines to enable local in file.
// config/database.php
...
...
'mysql' => [
...
...
'driver' => 'mysql',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
PDO::MYSQL_ATTR_LOCAL_INFILE => true, // this must be true
]) : [],
],
Restart server and clear configs and cache:
php artisan config:clear
php artisan cache:clear
php artisan serve
That it, now your are go to.
