Laravel: General error: 1615 Prepared statement needs to be re-prepared

It seems to work adding

'options'   => [                \PDO::ATTR_EMULATE_PREPARES => true            ]

Inside projectName/config/database.php file in DB configuration. It will be like this:

'mysql' => [    'driver'    => 'mysql',    'host'      => env('DB_HOST', 'localhost'),    'database'  => env('DB_DATABASE', 'forge'),    'username'  => env('DB_USERNAME', 'forge'),    'password'  => env('DB_PASSWORD', ''),    'charset'   => 'utf8',    'collation' => 'utf8_unicode_ci',    'prefix'    => '',    'strict'    => false,    'options'   => [        \PDO::ATTR_EMULATE_PREPARES => true    ]],

Laravel 5.1. Hope it will help!

As per the comments in the accepted answer, running

SET GLOBAL table_definition_cache = 1024

in the MariaDB solved the problem.

Seems like it's a MySQL Bug that has been documented.

Edit:

Is your model using 'id' as the primary key? I like to set the primary key explicitly in the model even if it is.

protected $primaryKey = 'id'; // If different than id, definitely need to set the column here

You can also try commenting out the hasMany() functions and trying again. Sometimes Laravel can do weird things on eagerLoad, especially if there are A LOT of records that it is trying to map to.
