Laravel makes connecting with databases and running queries extremely simple. The database configuration file is app/config/database.php. In this file you may define all of your database connections, as well as specify which connection should be used by default. Examples for all of the supported database systems are provided in this file.
Currently Laravel supports four database systems: MySQL, Postgres, SQLite, and SQL Server.
Once you have configured your database connection, you may run queries using the DB class.
Running A Select Query
$results = DB::select('select * from users where id = ?', array(1));
The select method will always return an array of results.
Running An Insert Statement
DB::insert('insert into users (id, name) values (?, ?)', array(1, 'Dayle'));
Running An Update Statement
DB::update('update users set votes = 100 where name = ?', array('John'));
Running A Delete Statement
DB::delete('delete from users');
Note: The
updateanddeletestatements return the number of rows affected by the operation.
When using multiple connections, you may access them via the DB::connection method:
$users = DB::connection('foo')->select(...);
