Bulk Updates

Staff,

 

Need an idea of how to upgrade over 20,000 records with an apex class.


I was thinking about scheduling the service and leave running overnight, however the limits have to be respected.

Does anyone have any idea how I can perform this update?

 

 

thank you

If you really want to do it using an apex class, I would suggest a Visual Force page, on a custom tab, with an 'upload file' button.  Ask a bunch of different users to each load their own file of less than 20K.  

 

Any chance you can use the Data Loader which can be run from a desktop?

You should be using Batch Class to update the records and then schedule it to run at a particular time.

Please go through the below links for the same :-
