DataAbilityResult

定义DataAbility数据操作结果，通过executeBatch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

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	必填	说明
uri?	string	否	指示待处理的DataAbility。例：'dataability:///com.example.xxx.xxxx'。
count?	number	否	指示受操作影响的数据数量。

示例：

import featureAbility from '@ohos.ability.featureAbility';

// 批量执行数据库操作
function executeBatchOperation() {
    let dataAbilityUri = ('dataability:///com.example.myapplication.TestDataAbility');
    let DAHelper;
    try {
        DAHelper = featureAbility.acquireDataAbilityHelper(dataAbilityUri);
        if (DAHelper === null) {
            console.error('DAHelper is null');
        }
    } catch (err) {
        console.error('acquireDataAbilityHelper fail, error: ${JSON.stringify(err)}');
    }

    let valueBucket = {
        'name': 'DataAbilityHelperTest',
        'age': 24,
        'salary': 2024.20,
    };
    let operations = [
    {
        uri: dataAbilityUri,
        type: featureAbility.DataAbilityOperationType.TYPE_INSERT,
        valuesBucket: valueBucket,
        predicates: null,
        expectedCount: 1,
        PredicatesBackReferences: {},
        interrupted: true,
    },
    {
        uri: dataAbilityUri,
        type: featureAbility.DataAbilityOperationType.TYPE_INSERT,
        valuesBucket: valueBucket,
        predicates: null,
        expectedCount: 1,
        PredicatesBackReferences: {},
        interrupted: true,
    }
    ];

    try {
        DAHelper.executeBatch(dataAbilityUri, operations).then((data) => {
            for (let i = 0; i < data.length; i++) {
                let dataAbilityResult = data[i];
                console.log('dataAbilityResult.uri: ${dataAbilityResult.uri}');
                console.log('dataAbilityResult.count: ${dataAbilityResult.count}');
            }
        }).catch(err => {
            console.error('executeBatch error: ${JSON.stringify(err)}');
        });
    } catch (err) {
        console.error('executeBatch error: ${JSON.stringify(err)}');
    }
