SQLSRV查詢失敗，致命錯誤'達到'256'的最大功能嵌套級別，正在中止！'

我有多個數據庫連接在config/database.php：SQLSRV查詢失敗，致命錯誤'達到'256'的最大功能嵌套級別，正在中止！'

'connections' => [ 
    'mysql' => [ 
     'driver' => 'mysql', 
     'read' => [ 
      'host' => env('DB_READ_HOST', 'localhost'), 
     ], 
     'write' => [ 
      'host' => env('DB_WRITE_HOST', 'localhost'), 
     ], 
     'database' => env('DB_DATABASE', ''), 
     'username' => env('DB_USERNAME', ''), 
     'password' => env('DB_PASSWORD', ''), 
     'charset' => 'utf8', 
     'collation' => 'utf8_unicode_ci', 
     'prefix' => '', 
     'strict' => false, 
    ], 
    'sqlsrv' => [ 
     'driver' => 'sqlsrv', 
     'host'  => 'localhost', 
     'database' => 'mytest', 
     'username' => '', 
     'password' => '', 
     'charset' => 'utf8', 
     'prefix' => '', 
    ], 
]

我用Query Builder從SQLSERVER qyery數據：

DB::connection('sqlsrv')->table($this->table) 
    ->where('FDate', date('Ymd')) 
    ->take(1) 
    ->get();

，並會得到Fatal error：

我改變xdebug設置如下：

[xdebug] 
zend_extension="/usr/local/opt/php56-xdebug/xdebug.so" 
xdebug.max_nesting_level = 1000

但它仍然有相同的錯誤。
這發生在Laravel 5.1.25（LTS）中。

我的PHP版本如下：

PHP 5.6.16 (cli) (built: Nov 28 2015 22:22:08) 
Copyright (c) 1997-2015 The PHP Group

我會檢查在$this->table正在使用的表名。它有別名嗎？它是否包含數據庫名稱，然後是表名？

在照亮\數據庫\語法： https://github.com/laravel/framework/blob/5.1/src/Illuminate/Database/Grammar.php#L77 wrapTable()電話wrap()和wrap()可以調用wrapTable()。

取決於表名稱，它可能會進入一個巨大的遞歸循環
