DataAbilityResult

The DataAbilityResult module defines the operation result on DataAbilities. When you call executeBatch to operate the database, the operation result is returned through the DataAbilityResult object.

NOTE

The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version. The APIs of this module can be used only in the FA model.

System capability: SystemCapability.Ability.AbilityRuntime.FAModel

Example

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

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,

    valuesBucket: valueBucket,
    predicates: null,
    expectedCount: 1,

];

try {
    let promise = DAHelper.executeBatch(dataAbilityUri, operations).then((data) => {
        for (let i = 0; i < data.length; i++) {
