# DataAbilityResult

The **DataAbilityResult** module defines the operation result on DataAbilities. When you call [executeBatch](js-apis-inner-ability-dataAbilityHelper.md#dataabilityhelperexecutebatch) 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.

// Perform database operations in batches.
function executeBatchOperation() {
    let dataAbilityUri = ('dataability:///com.example.myapplication.TestDataAbility');

    try {
        DAHelper = featureAbility.acquireDataAbilityHelper(dataAbilityUri);

            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 = [

                console.log('dataAbilityResult.uri: ${dataAbilityResult.uri}');
                console.log('dataAbilityResult.count: ${dataAbilityResult.count}');
