Update any record without using apex class in LWC

Update records using uiRecordApi in Lightning web components

Sometimes we need to update some fields after checking some conditions. It may be same record or some other records. for this we don't need to create apex class to do this. Salesforce does allow do this using uiRecordApi. 

1. Import getRecord, getFieldValue, updateRecord methods from uiRecordApi.

[import {getRecord, getFieldValue, updateRecord} from 'lightning/uiRecordApi';]

2. Call the getRecord method to get current records field values.

[const fields = [OPPORTUNITY_NAME_FIELD, ACCOUNT_NAME_FIELD, ACCOUNT_ID_FIELD];

    // Wire method to get the data of fields

    @wire(getRecord, { recordId: '$recordId', fields })

    opportunity;]

3. Now call getFieldValue to get the field values.

[let oppName = getFieldValue(this.opportunity.data, OPPORTUNITY_NAME_FIELD);

//let oppName = this.opportunity.data.fields.Name.value; // Also access this way]

4. Now create an object of fields to update then pass that fields object to updateRecord method to update. here in field object Id field is mandatory to update.

[let fields = {

Id: accId,

Name: oppName

}

const recordInput = { fields };

updateRecord(recordInput);]

Ex: We have an opportunity record, on opportunity details page, create a button to check and update the Name of opportunity should be same as account Name, if not then it will update account Name to match with opportunity.
