# DataAbilityResult

定义DataAbility数据操作结果，通过[executeBatch](js-apis-inner-ability-dataAbilityHelper.md#dataabilityhelperexecutebatch)操作数据库时，操作结果使用DataAbilityResult对象返回。

> **说明：**
> 
> 本接口从API version 7开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
> 本接口仅可在FA模型下使用

## 导入模块

```ts
import ability from '@ohos.ability.ability';
```

## 属性

**系统能力**：以下各项对应的系统能力均为SystemCapability.Ability.AbilityRuntime.FAModel

| 名称      | 类型  | 只读  | 可选    |       说明   |
| -------- | -------- | -------- | -------- | -------- |
| uri      | string    | 否  | 是    | 指示待处理的DataAbility。例：'dataability:///com.example.xxx.xxxx'。  |
| count     | number   | 否  | 是    | 指示受操作影响的数据数量。  |
