import { LightningElement, wire, track } from 'lwc';
import getContacts from '@salesforce/apex/LWCExampleController.getContacts';
import { updateRecord } from 'lightning/uiRecordApi';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import { refreshApex } from '@salesforce/apex';
// datatable columns

// Updateing the records using the UiRecordAPi
const promises = recordInputs.map(recordInput => updateRecord(recordInput));
Promise.all(promises).then(res => {

}
// This function is used to refresh the table once data updated
async refresh() {
await refreshApex(this.contacts);
}
}Apex Code:
public inherited sharing class LWCExampleController {
@AuraEnabled(Cacheable = true)
public static List<Contact> getContacts() {
return [SELECT Id, Name, FirstName, LastName, Phone, Email
FROM Contact
WHERE Email != null
AND Phone != null
ORDER BY CreatedDate DESC NULLS LAST limit 10];
}
}
Output:
