/**
@fn tableCRUD($ac, $tbl, $asAdmin?=false)
对象型接口的入口。
也可直接被调用，常与setParam一起使用, 提供一些定制的操作。
@param $asAdmin 默认根据用户身份自动选择"AC_"类; 如果为true, 则以超级管理员身份调用，即使用"AC0_"类。
设置$asAdmin=true好处是对于超级管理员权限来说，即使未定义"AC0_"类，默认也可以访问所有内容。
假如有Rating（订单评价）对象，不想通过对象型接口来查询，而是通过函数型接口来定制输出，接口设计为：
queryRating(storeId, cond?) -> tbl(id, score, dscr, tm, orderDscr)
查询店铺storeId的订单评价。
应用逻辑：
- 按时间tm倒排序
底层利用tableCRUD实现它，这样便于保留分页、参数cond/gres等特性:
function api_queryRating()
{
$storeId = mparam("storeId");
// 定死输出内容。
setParam("res", "id, score, dscr, tm, orderDscr");
// 相当于AccessControl框架中调用 addCond，用Obj.query接口的内部参数cond2以保证用户还可以使用cond参数。
setParam("cond2", ["o.storeId=$storeId"]);
// 定死排序条件
setParam("orderby", "tm DESC");
$ret = tableCRUD("query", "Rating", true);
return $ret;
}
注意：
- 以上示例中的设计不可取，应使用标准对象接口来实现这个需求。
