Laravel 5.8. I am trying to save an Eloquent model, choosing the database connection at runtime:
$catModel = new Cat;
if (env('USE_STAGING')) {
$catModel->setConnection('staging');
}
$cat = $catModel::create(['name' => $request->name]);
My config/database.php file:
'default' => env('DB_CONNECTION', 'mysql'),
'connections' => [
'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,
],
'staging' => [
'driver' => 'mysql',
'host' => env('STAGING_DB_HOST', '127.0.0.1'),
'port' => env('STAGING_DB_PORT', '3306'),
'database' => env('STAGING_DB_DATABASE', 'forge'),
'username' => env('STAGING_DB_USERNAME', 'forge'),
'password' => env('STAGING_DB_PASSWORD', ''),
'unix_socket' => env('STAGING_DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
],
My problem is that each time I run this code, the cat is created in the mysql (default) database, rather than the staging database, even when USE_STAGING is true.
The problem is the static call of the create() method.
By changing $catModel::create() to $catModel->create() it should use the correct connection:
$catModel = new Cat;
if (env('USE_STAGING')) {
$catModel->setConnection('staging');
}
$cat = $catModel->create(['name' => $request->name]);

I am developing a laravel application. I connect my laravel application with a mysql database. But I need a table data that is in another server and that database is sql database is in IIS server.

I need help to use two databases from different server (one from mysql and another from sql) on my same laravel application.
In your config/database.php
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),

'prefix' => '',
'prefix_indexes' => true,
'strict' => false,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
// Add this (Connect sql server)
//TCP port 1433 is typically the port used by a default instance of SQL Server
'sqlsrv' => [
'driver' => 'sqlsrv',
'url' => env(''),
'host' => env('DB_HOST', 'X.X.X.X'),
'port' => env('DB_PORT', '1433'),

'charset' => 'utf8mb4',
'prefix' => '',
'prefix_indexes' => true,

Get your mysql table
$mysql = DB::connection('mysql')->table('xxx')->select('*')->get();
Get your sql server table
$sqlsrv= DB::connection('sqlsrv')->table('xxx')->select('*')->get();
I need to append dynamically connection in the database.php file using PHP code, is it possible or not?
It is working for me
When I create a new customer then
public function setConnection($tenantName){
//GET Database Connection file path
$path = config_path('database.php');
//GET Database Connection file
$arr = include $path;
// load the array from the file
$new_connection=[
'driver' => 'mysql',
'host' => env('DB_HOST'),
'database' => $tenantName,
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false
];
// modify the array
$arr['connections'][$tenantName]=$new_connection;
// write it back to the file
file_put_contents($path, "<?php return " . var_export($arr, true) . ";");
}
It's possible to have multiple database connections and explicitly execute queries on one of them: https://laravel.com/docs/8.x/database#using-multiple-database-connections
The config/database.php has to return an array where config('database.connections') contains an array with keys representing different database engines but it's totally possible to for example add mysql2 and mysql3 to that array.
For example:
<?php
use Illuminate\Support\Str;
$customConnections = [];
for(var $i = 1; $i < 5; $i++) {
$customConnections['mysql'.$i] = [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '330'.$i),
'database' => env('DB_DATABASE', 'mysql'.$i),
'username' => env('DB_USERNAME', 'mysql'.$i),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
];

I'm trying to connect 2 database on my system with laravel 5, and when I try to get data from one I skip this error
Database [dpnmwin] not configured.

the error comes out when he tried to bring data from the dpnmwin database, as follows
public function index(){
$users = DB::connection('dpnmwin')->select('select * from datos_itu');
return view('users.list',array(
'users' => $users
));
}
but if I want to bring data from my other database spi_intranet
public function index(){
$users = User::all();
return view('users.list',array(
'users' => $users
));
}
it brings me the data without problems.
Why do not you bring me the data from my other database?
Is it a problem in the configuration?
You have to pass connection name, change this line and pass mysql2 as connection name.
$users = DB::connection('mysql2')->select('select * from datos_itu');

'mysql' => [

But if I want to use different access information as DB_NAME, USER_ID, PASS etc to each read/write databases, then how could I make it? Thank you.
You can create two connections then specify the connection with Eloquent using the on method:
'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,
],
'mysql2' => [
'driver' => 'mysql',
'host' => env('DB_HOST2', '127.0.0.1'),
'port' => env('DB_PORT2', '3306'),
'database' => env('DB_DATABASE2', 'forge'),
'username' => env('DB_USERNAME2', 'forge'),
'password' => env('DB_PASSWORD2', ''),
'unix_socket' => env('DB_SOCKET2', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
User::on('mysql2')->where('id', $id)->update($data);
Or using Query Builder:
DB::connection('mysql2')->table('users')->where('id', $id)->update($data);
You can declare another db conecction like this:
'mysql' => [
'read' => [
'host' => '192.168.1.1',
],
'write' => [
'host' => '192.168.1.1'
],
'sticky' => true,
'driver' => 'mysql',
'database' => 'database',
'username' => 'root',
'password' => '',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
],
'writecon' => [
'read' => [
'host' => '196.168.1.2',
],
'write' => [
'host' => '196.168.1.2'
],
'driver' => 'mysql',
'port' => env('DB2_PORT', '3306'),
'database' => env('DB2_DATABASE', 'db2'),
'username' => env('DB2_USERNAME', 'somename'),
'password' => env('DB2_PASSWORD', 'somepass'),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
],
Then in your .env add:
DB2_PORT=3306
DB2_DATABASE=db2
DB2_USERNAME=somename
DB2_PASSWORD=somepass
And you can use it like this:
$someModel->setConnection('writecon');
$someModel->save();
not tested but you can try it.
I created a second connection in my config/database.php and will also create a third connection, wanted to know how can I do to switch between these connections according to the logged in user.
config/database.php
'connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'database2' => [
'driver' => 'mysql',
'host' => ('localhost'),
'port' => ('3306'),
'database' => ('database2'),
'username' => ('root'),
'password' => (''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,

I know I can choose my modem connection in that way, but how do you that name "database2" is pulled from the logged in user instead of being placed the name directly there?
class Empresa extends Model
{
protected $connection;
function __construct()
{
return $this->connection = 'database2';
}
}
I tried to put it that way, but it did not work.
return $this->connection = Auth::user()->database;
He gave this error.
