How can we activate/ deactivate trigger/ validation rule and workflow using Salesforce Apex Code?

Hi Rahul,

Practically this is not possible directly using apex code. But there is another way to do this.

You can create a custom label or custom setting with checkbox which can be updated using apex code and you can implement condition to fire Validation rule or workflow with checkbox true else this will not fire if condition will be false.

Hope this will help you.

Thanks,

Prafull
