Lightning data table not updated after dml

I am creating a Lightning web component that displays a list of records in a lightning-data table. After saving a new record to the database, the list is not updating. the code is here:

@wire(recordList, { recorded: '$recordId' })records(results) {
if (results.data) {
    this.data = results.data;
} else if (results.error) {
    this.showToast(results.error);
}}

What should I need to change in the code above for creating a Lightning web component that displays a list of records in a lightning-data table? I also find the same question at this source: https://www.pass4future.com/questions/salesforce/pdii
but I am still unable to do this.

It looks like you're working with a Lightning Web Component (LWC) and are facing an issue where the data table is not updating after a DML operation. This is a common issue when the component does not automatically refresh to reflect changes in the underlying data. Here are a few suggestions to help you resolve this:

  1. Use refreshApex: After performing a DML operation, you can use the refreshApex function to refresh the data in your component. This function forces a refresh of the data from the server. You need to import refreshApex from @salesforce/apex and call it after your DML operation.

```javascript import { refreshApex } from '@salesforce/apex';

// After your DML operation refreshApex(this.records); ```

  1. Ensure Reactive Properties: Make sure that the properties you are using in your component are reactive. In your case, this.data should be a reactive property. If it's not updating, ensure that it is declared as a reactive property using @track (if you're using an older version of LWC) or simply as a class field (in newer versions).

  2. Check for Errors: Ensure that there are no errors in your DML operation that might be preventing the data from being saved correctly. You can add error handling to your DML operation to catch and log any errors.

  3. Verify Data Binding: Ensure that your data table is correctly bound to the this.data property. If the data table is not bound correctly, it won't update when this.data changes.

  4. Debugging: Use console logs to debug and ensure that the results.data is being updated correctly after the DML operation.

Here's a modified version of your code with refreshApex:

import { LightningElement, wire } from 'lwc';
import { refreshApex } from '@salesforce/apex';
import recordList from '@salesforce/apex/YourApexClass.recordList';

export default class YourComponent extends LightningElement {

data;

wiredRecords;


@wire(recordList, { recorded: '$recordId' })
records(results) {
    this.wiredRecords = results;
    if (results.data) {
        this.data = results.data;
    } else if (results.error) {
        this.showToast(results.error);
    }
}

handleDmlOperation() {
    // Perform your DML operation here

    // Refresh the data
    refreshApex(this.wiredRecords);
}

showToast(error) {
    // Implement your toast notification logic here
}



}

Make sure to replace YourApexClass and recordList with the actual names used in your project. This should help ensure that your data table updates correctly after a DML operation.
