我正在尝试在 Laravel $posts= DB::table('rmm') 中运行以下代码

        ->select( array('message', DB::raw('COUNT(message) as number'), DB::raw('rmm.receivedTime as time')))

        ->join( 'rcs', 'rmm.smsCid', '=', 'rcs.smsCid', 'INNER') 

        ->where(DB::raw('rcs.status =1 and rmm.receivedTime > \'2012-12-26\' and rmm.receivedTime LIKE \'2013-04-01\' and length(\'message\') >\'3\' '))

        ->group_by('message')

        ->get();

并得到下面的错误代码

SQLSTATE[42000]：语法错误或访问冲突：1064 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以获取在 '? 附近使用的正确语法。GROUP BY message' 在第 1 行

SQL: SELECT `message`, COUNT(message) as number, rmm.receivedTime as time FROM `rmm` INNER JOIN `rcs` ON `rmm`.`smsCid` = `rcs`.`smsCid` WHERE rcs.status =1 and rmm.receivedTime > '2012-12-26' and rmm.receivedTime LIKE '2013-04-01' and length('message') >'3'   ? GROUP BY `message`

Bindings: array (
  0 => NULL,
)

它以某种方式?在查询中产生；如果我解决了这个问题，我确定它会起作用吗？

尝试raw_where()：

->raw_where("rcs.status = 1 AND rmm.receivedTime > '2012-12-26' AND rmm.receivedTime LIKE '2013-04-01' AND length('message') > 3")
