SFDX:Create Apex Class >> New >> lwcAppExampleApex.cls

lwcAppExampleApex.cls [Apex Class]

 public WITH sharing class lwcAppExampleApex {

```
 
```
```
 
```

   //DELETE multiple contact record IN LWC

```
    @AuraEnabled(cacheable=TRUE)
```

    public static List<Contact> fetchContactRecord(){

        List<Contact> conList = [SELECT Id, FirstName, LastName, Email, Phone FROM Contact ORDER BY createdDate DESC LIMIT 10 ];

```
        RETURN conList;
```
```
    }
```
```
 
```
```
    @AuraEnabled

Step 3:- Create Lightning Web Component : lwdDeleteMultipleRecord.js

SFDX:Lightning Web Component >> New >> lwdDeleteMultipleRecord.js

lwdDeleteMultipleRecord.js [LWC JavaScript File]

  import { LightningElement, wire,api, track } from 'lwc';

import fetchContactRecord from '@salesforce/apex/lwcAppExampleApex.fetchContactRecord';

import deleteMultipleContactRecord from '@salesforce/apex/lwcAppExampleApex.deleteMultipleContactRecord';

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

import {ShowToastEvent} from 'lightning/platformShowToastEvent';

```
 
```
```
 
```

export default class LwdDeleteMultipleRecord extends LightningElement {

```
    @api  columns =[
```

        { label: 'First Name', fieldName: 'FirstName', type:'text'},

        { label: 'Last Name', fieldName: 'LastName',type:'text' },

        { label: 'Email', fieldName: 'Email', type:'Email'}

```
    ];
```
```
 
```
```
 
```

    @wire (fetchContactRecord) wireContact;

```
 
```
```
    @api selectedContactIdList=[];
```
```
    @track errorMsg;
```
```
 
```
```
 
```
```
    getSelectedIdAction(event){
```

        const selectedContactRows = event.detail.selectedRows;

        window.console.log('selectedContactRows# ' + JSON.stringify(selectedContactRows));

```
        this.selectedContactRows=[];
```
```
 
```

        for (let i = 0; i<selectedContactRows.length; i++){

            this.selectedContactIdList.push(selectedContactRows[i].Id);

```
        }
```
```
 
```

       // window.console.log('selectedContactRows1 ' + this.selectedContactRows + selectedContactRows.length );

```
    }
```
```
 
```
```
 
```
```
    deleteContactRowAction(){
```

        deleteMultipleContactRecord({conObj:this.selectedContactIdList})

```
        .then(()=>{
```

            this.template.querySelector('lightning-datatable').selectedContactRows=[];

```
 
```

            const toastEvent = new ShowToastEvent({

```
                title:'Success!',
```

                message:'Record deleted successfully',

```
                variant:'success'
```
```
              });
```

              this.dispatchEvent(toastEvent);

```
 
```

            return refreshApex(this.wireContact);

```
        })
```
```
        .catch(error =>{
```
```
            this.errorMsg =error;
```

            window.console.log('unable to delete the record due to ' + JSON.stringify(this.errorMsg));

```
        });
```
```
    }
```
```
 
```
```
}
```

Step 4:- Create Lightning Web Component : lwdDeleteMultipleRecord.js-meta.xml

SFDX:Lightning Web Component >> New >> lwdDeleteMultipleRecord.js-meta.xml

lwdDeleteMultipleRecord.js-meta.xml [LWC Meta Data XML]

  <?xml version="1.0" encoding="UTF-8"?>

<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata">

```
    <apiVersion>45.0</apiVersion>

```
    <isExposed>true</isExposed>
```
```
    <targets>
```

        <target>lightning__AppPage</target>

        <target>lightning__RecordPage</target>

        <target>lightning__HomePage</target>

FAQ (Frequently Asked Questions)

How do I delete records in LWC?

To delete records in LWC, we first need to import fetchOpportunities method from Apex Controller using @salesforce/apex/ module in JS Controller. Then, include deleteRecord method from lightning/uiRecordApi module.

How many records can be deleted at once using the mass delete tool?

You can delete up to 250 items at one time. When you delete a record, any associated records that display on that record's related lists are also deleted.

How do you refresh apex in LWC?

To refresh stale Apex data, invoke the Apex method and then call getRecordNotifyChange(recordIds) to update the Lightning Data Service (LDS) cache. Lightning Data Service doesn't manage data provisioned by imperative Apex calls.
