I have this migration file:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::connection('DB1')->create('feed_mappings', function (Blueprint $table) {
$table->bigIncrements('id_feed')->autoIncrement();
$table->string('id_project', 255);
$table->string('import_field_slug', 155);
$table->string('internal_field_slug', 155);
$table->tinyInteger('import');
$table->tinyInteger('custom_field')->default(0);
$table->dateTime('date_add');
$table->dateTime('date_upd');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('feed_mappings');
}
};
And I have this config in the database.php file:
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'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' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
'DB1' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '8889'),
'database' => env('DB_DATABASE', 'DB1'),

'password' => env('DB_PASSWORD', 'root'),

'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
Now, I have run this command :
php artisan migrate:refresh --seed
Now, All the migration file is creating a tables on default database but I want this feed_mappings should go to DB1 database.
BUT this feed_mapping is not going to DB1 database. Can you tell me why?
So the issue is in your database.php file where you are using the same variables for connections 1 and 2
'mysql' => [
'driver' => 'mysql',
***'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),

'password' => env('DB_PASSWORD', ''),***
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),

],
'DB1' => [
'driver' => 'mysql',
**'url' => env('DATABASE_URL'),

'database' => env('DB_DATABASE', 'DB1'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'root'),**
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,

'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
what you need to do is create separate variables for db connections e.g:
DB_HOST // for connection 1
DB_HOST_2 // for connection 2

I am in new laravel, In my application When a user logs into his account I want to change the default database prefix from the env file. I setup wildcard subdomain for every users. When every user logs in I want to change the database prefix according to the sub domain.
So is it possible to change the laravel prefix globally if a user logs in Laravel?. Please suggest me if there is any solution. Thanks is advance.
Of course you can:
config/database.php
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'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' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'mysql_earth' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_EARTH_DATABASE', 'earth'),
'username' => env('DB_EARTH_USERNAME', 'earth'),
'password' => env('DB_EARTH_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'mysql_moon' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_MOON_DATABASE', 'moon'),
'username' => env('DB_MOON_USERNAME', 'moon'),
'password' => env('DB_MOON_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
.env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=forge
DB_USERNAME=forge
DB_PASSWORD=forgepw
DB_EARTH_DATABASE=earth
DB_EARTH_USERNAME=erth
DB_EARTH_PASSWORD=earthpw
DB_MOON_DATABASE=moon
DB_MOON_USERNAME=moon
DB_MOON_PASSWORD=moonpw
Use in your Controller example put your conditions on the connection and then you can have the query in each database:
$db = \DB::connection('mysql');
$db = \DB::connection('mysql_earth');
$db = \DB::connection('mysql_moon');
$products = $db->table('products')
->distinct()
->select("*" )
->orderBy('products.id','asc')
->get();
I have use multiple database in my project. But is that possible to use multiple connection in single query in laravel? This is my connection config.
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'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' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
'mysql_pdd' => [
'driver' => 'mysql',
'host' => env('DB_PDD_HOST', '127.0.0.1'),
'port' => env('DB_PDD_PORT', '3306'),
'database' => env('DB_PDD_DATABASE', 'forge'),
'username' => env('DB_PDD_USERNAME', 'forge'),
'password' => env('DB_PDD_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
I want to join a tabel in my mysql connection to mysql_pdd table. Is that possible?
Yes, you can but for that you need to put condition, when you want to connect 'mysql' and when 'msql_pdd'.
if (mysql_connection){
$mysql =DB:: reconnect('mysql');
}else if(mysql_pdd_connection){
$mysql_pdd =DB:: reconnect('mysql_pdd');
}
Using $mysql & $mysql_pdd you can perform joins as well by code not by query.
We've using Lumen for building API's , Now we need to access multiple databases.
Currently using .env for database config but unable to found the way to multiple databases in .env
where we need to read 2nd connection ...
First, you'll need to configure your connections. If you don't already have one you'll need to create a config directory in your project and add the file config/database.php. It might look like this:
<?php
return [
'default' => 'accounts',
'connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST'),
'port' => env('DB_PORT'),
'database' => env('DB_DATABASE'),
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
'mysql2' => [
'driver' => 'mysql',
'host' => env('DB2_HOST'),
'port' => env('DB_PORT'),
'database' => env('DB2_DATABASE'),
'username' => env('DB2_USERNAME'),
'password' => env('DB2_PASSWORD'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
],
];
Once you've added your connection configurations, you can access them by getting the database manager object out of the container and calling ->connection('connection_name').
// Use default connection
app('db')->connection()->select('xx');
DB::connection()->select('yy');
// Use mysql2 connection
app('db')->connection('mysql2')->select('xx');
DB::connection('mysql2')->select('yy');
Hope this helps you!!
This also worked. In the current version of Lumen 5.7
config/database.php
<?php
return [
'default' => env('DB_CONNECTION', 'sqlsrv'),
'migrations' => 'migrations',
'connections' => [
'sqlsrv' => [
'driver' => 'sqlsrv',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '1433'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),

'port' => env('DB_PORT', '1433'),
'database' => env('DB_DATABASE2', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'prefix' => '',
'prefix_indexes' => true,
],
],
];
.env
DB_CONNECTION=sqlsrv
DB_HOST=localhost
DB_PORT=1433
DB_DATABASE=database1
DB_USERNAME=username
DB_PASSWORD=password
DB_DATABASE2=database2
Usage:
Model: protected $connection = 'sqlsrv2';
Other: ->connection('sqlsrv2')
I hope i help you!

I am trying to set a separate database for tests. For some reason when I run the migrations I have always a message saying: "Nothing to migrate."
Here is how I run the migrations:
php artisan migrate --database=mysql_test
Nothing to migrate.
And here is my config/database.php:
'default' => env('DB_CONNECTION', 'mysql'),
'connections' => [
'sqlite' => [
'driver' => 'sqlite',
'database' => env('DB_DATABASE', database_path('database.sqlite')),
'prefix' => '',
],
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'mydb'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'dev'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
'mysql_test' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'mydbtest'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'dev'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
And obviously I can login to the database mydbtest with the credentials in the config.
Updating here after some troubleshooting:
After emptying mydb database and running the same command it filled the mydb database not mydbtest. This means it does not take into account what I am giving as database connection name.
Any suggestions to troubleshoot this are welcome.
Thanks
I found the problem.
After commenting out this line in my .env file it works now:
#DB_DATABASE=mydb
Thanks
