Is it possible to Deactivate a trigger from Apex in Salesforce? If yes, then how?

Hi Ankit,

You could do this from Force.com IDE.

Find the trigger.meta.xml of respective trigger and make this change and deploy.

<?xml version="1.0" encoding="UTF-8"?>
<ApexTrigger xmlns="http://soap.sforce.com/2006/04/metadata">
<apiVersion>40.0</apiVersion>
<status>Inactive</status>
</ApexTrigger>

Hope this helps you.

Hello Ankit,

The best possible way to choose below options to Inactive trigger in production.

a) via Force.com IDE,
Disable the trigger in sandbox environment [You should have a sandbox org which contains the same trigger]
Create a new project in Eclipse using the Sandbox and including the trigger (or refresh your existing Eclipse project)
1. Alternative: edit the triggername.trigger-meta.xml in an existing project and change the status node to false: <status>Inactive</status>
2. Save the change locally Deploy the trigger to production
Complete the data load
If the change is not permanent or you want to enable the trigger again then enable the trigger by making it active on the sandbox or project again and deploy it to production

b) via Changesets,
Disable the trigger in a Sandbox environment [You should have a Sandbox org which contains the same trigger]
Create a new Outbound Change Set in the Sandbox
Add the disabled trigger to the Change Set
Upload the Change Set to your Production Org
In Production, go to Inbound Change Sets and wait for the uploaded Change Set to be available
Click Deploy to run the tests and apply the changes

Hope It would be helpful !!
