ローカルPCでは正常に動いていたのに、さくらサーバで動かすと以下のようなエラーが発生した場合
SQLSTATE[HY000]: General error: 1615 Prepared statement needs to be re-prepared
■解決策
config/database.phpに’PDO::ATTR_EMULATE_PREPARES => true,’を追記することで解決
config/database.php
'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'),

'charset' => 'utf8',

'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
PDO::ATTR_EMULATE_PREPARES => true, <- この行を追加!!
]) : [],
],
