Step 2:- Create Lightning Web Component : wireDecoratorsDataTable.js

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

wireDecoratorsDataTable.js [LWC JavaScript File]

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

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

```
 
```

import {NavigationMixin} from 'lightning/navigation';

```
 
```

export default class wireDecoratorsDataTable extends NavigationMixin (LightningElement) {

```
  @api title;
```
```
  @api greetings;
```
```
  @track greeting;
```
```
 
```

    //Using @wire decorator in lwc for the lightning data table

```
    @track accData;
```
```
    @track errorAccData;     
```
```
 
```
```
    @track columnTable =[
```

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

        {label:'Phone',fieldName:'Phone',type:'text'},

        {label:'Industry',fieldName:'Industry',type:'text'},

```
    ];
```
```
 
```
```
    @wire(getAccountList)
```
```
 
```
```
    dataTableAcc({data, error}){
```
```
         if(data){
```
```
           this.accData = data;
```
```
        }
```
```
        else if(error){
```
```
          this.errorAccData = error;  
```
```
        }
```
```
 
```
```
    }
```
```
 
```
```
}
```

Step 3:- Create Lightning Web Component : wireDecoratorsDataTable.js-meta.xml

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

wireDecoratorsDataTable.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>

```
      </targets>
```
```
      <targetConfigs>
```

         <targetConfig targets="lightning__AppPage">

           <property name="title" type="string"/>

           <property name="greetings" type="string"/>

```
         </targetConfig>
```
```
      </targetConfigs>
```
```
</LightningComponentBundle>
```

Step 5:- Create Lightning Web Component : lwcAppExampleApex.cls

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

lwcAppExampleApex.cls [Apex Class]

   public WITH sharing class lwcAppExampleApex {

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

    public static List<Account> getAccountList(){

        List<Account> accList = [SELECT Id, Name, Phone, Industry FROM Account WHERE Name !=NULL LIMIT 5];

```
        RETURN accList;
```
```
    }   
```
```
 
```

FAQ (Frequently Asked Questions)

How do you use a wire decorator in LWC?

When the wire service provisions data, the component rerenders. Components use @wire in their JavaScript class to specify a wire adapter or an Apex method. We need to import the @salesforce/apex scoped module into JavaScript controller class. import apexMethodName from '@salesforce/apex/Namespace.

What is wire adapter in LWC?

Lightning web components(LWC) use a reactive wire service, which is built on Lightning Data Service. Components use @wire in their JavaScript class to read data from one of the wire adapters in the lightning/ui*Api modules and also to call the apex controller server-side methods using wire services.

What is @API @track and @wire?

To track a private property's value and re-render a component when it changes, decorate the property with @track. Tracked properties are also called private reactive properties. @wire. To read Salesforce data, Lightning web components use a reactive wire service.
