All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`forceExecQuery()` 如果sql的类型无法被nutz识别,而这个sql有的确是个查询,那么调用这个方法, 这样就强制nutz按select的方式执行
`String`	`forPrint()`
`protected ValueAdaptor`	`getAdapterBy(Object value)`
`boolean`	`getBoolean()` 无结果的话,会抛NPE
`SqlContext`	`getContext()` 获取 SQL 执行的上下文对象，以便做更多的操作
`double`	`getDouble()`
`double`	`getDouble(double defaultValue)`
`Entity<?>`	`getEntity()`
`float`	`getFloat()`
`float`	`getFloat(float defaultValue)`
`int`	`getInt()` 无结果的话,会抛NPE,可以考虑用getInt(defaultValue)
`int`	`getInt(int defaultValue)`
`<T> List<T>`	`getList(Class<T> classOfT)` 一个 getResult() 函数的变种，将当前对象的 Result 转换成 List 返回。如果 Result 本身就是一个列表，如果第一个元素的类型和参数相符，则直接返回，否则会被用 Castors 智能转换如果不是列表，则会强制用 ArrayList 包裹

    你可以通过 setCallback 函数为本语句设置一个回调。
    在回调中，你可以返回一个对象。这个对象会存储在本语句中。
    当本语句执行完毕，你可以通过这个函数获得回调函数生成的返回。
    一般的情况，回调函数是用来从 ResultSet 生成对象的。
    即，如果本语句不是 SELECT XXXX，一般不会被设置回调
