使用Laravel框架实现分页接口,返回数据表中特定字段:$$list=DB::table('booklist_table')->orderBy('create_time', 'asc')->paginate($size, ['id', 'title', 'author', 'image'])->toJson(); return json_decode($list, true);$$
用laravel 框架想实现一个分页接口,返回数据表中其中一部分字段
$list = DB::table('booklist_table')->orderBy('create_time','asc')->paginate($size,['id','title','author','image'])->toJson(); return json_decode($list,true);
结果运行报错
"SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' `title`, `author`, `image`) as aggregate from `booklist_table`' at line 1 (SQL: select count(`id`, `title`, `author`, `image`) as aggregate from `booklist_table`) ◀"
后来经过查询原因将代码改为
$list = DB::table('booklist_table')->select('id','title','author','image')->orderBy('create_time','asc')->paginate($size)->toJson();
结果正确!
