# 函数原型 ~~~ public function reset($sOption = null); ~~~ # 用法如下 ~~~ # SELECT `newtable`.* FROM `newtable` WHERE `newtable`.`new` = 'world' database::table ( 'test' ) ->where('id','=',5) ->where('name','like','me') ->reset() ->table('newtable') ->where('new','=','world') ->get (); # SELECT `test`.* FROM `test` WHERE `test`.`new` LIKE 'new' database::table ( 'test' ) ->where('id','=',5) ->where('name','like','me') ->reset('where') ->where('new','like','new') ->get (); ~~~
