我对laravel子查询非常陌生，我尝试获取另一个表数据，但它显示以下错误

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'SELECT tl_titlename FROM bm_titlelist WHERE tl_titleid=1 from `bm_customercon...' at line 1 (SQL: select SELECT tl_titlename FROM bm_titlelist WHERE tl_titleid=1 from `bm_customercontactinfo`)

查询

DB::enableQueryLog();
        $data = DB::table('bm_customercontactinfo')
                    ->select(
                            DB::raw("SELECT tl_titlename FROM bm_titlelist WHERE tl_titleid=1")
                    )
                    ->get();
        dd(DB::getQueryLog());

谁能帮我一下我错在哪里了？
