Updating the records using Batch


I am updating the records in below usecase:

- Get 60000 records by SOQL
- Prepare a list of 5000 records
- Update abouve records

As the operation is one time and long, how can i update the list using Batch.

thank you for rough code, please

Hi Sanrine,
To serve your purpose refer below rough code, and modify accordingly-
global class BatchApexExample implements Database.Batchable<sObject> {
    global Database.QueryLocator start(Database.BatchableContext BC) {
        //SOQL to collect the batches of 60000 records to be passed to execute
        String query = 'SELECT Id, Name FROM <your-sObject>';
        return Database.getQueryLocator(query);
    global void execute(Database.BatchableContext BC, List<sObject> scope) {
        // process each batch of records as per your requirement
        for(sObject sObj : scope) {        
            // Update the record            
        try {
            // Update the records into Database
            update scope;         
        } catch(Exception e) {
    global void finish(Database.BatchableContext BC) {
        // execute any post-processing operations like sending email
Let me know if this helps!
