So to avoid recursive behavior of trigger we make use of a static variable in Salesforce, for this we define another apex class with static Boolean variable and when our trigger runs for the first time we check the value of this Boolean variable and if it is true we allow further processing and in addition to further processing we set the value of this Boolean variable to false so as to avoid the second run of trigger in case if trigger fire another time due to updates.

What is recursive trigger in Salesforce?
Since Salesforce being multi-tenant architecture, Salesforce cannot allow as single org to monopolise the resources and thus stop the loop after 5 executions. This is called recursive triggers.

How do I stop an infinite loop in Salesforce?

Why is my trigger running twice?
Triggers can fire twice, once before workflows and once after workflows. Review step 12 in Trigger and Order of Execution. The before and after triggers fire one more time only when something needs to be updated. If the fields have already been set to a value, the triggers are not fired again.
How do you stop a recursive workflow?

How do you resolve a recursive trigger?
Handle recursion - To avoid the recursion on a trigger, make sure your trigger is getting executed only one time. You may encounter the error : 'Maximum trigger depth exceeded', if recursion is not handled well.
How do you stop an infinite loop from flowing?

How do you restrict a trigger to fire only once?
“The before and after triggers fire one more time only if something needs to be updated. If the fields have already been set to a value, the triggers are not fired again.” Workaround: Add a static boolean variable to a class, and check its value within the affected triggers.
What is Bulkify trigger in Salesforce?

When a batch of records initiates Apex, a single instance of that Apex code is executed, but it needs to handle all of the records in that given batch.
What is recursion in process builder?
Recursion allows for the record to be evaluated up to six times during a single save operation, this will allow other automation updates to occur during the same time if you have multiple. Next, add the criteria (if/then statement) that triggers the action.

Recursive Trigger In Apex
In this blog, we will learn how we can avoid the recursive triggers in apex code. In Salesforce it is recommended that there should be a single trigger for a single object. The reason behind this is you can not be sure about the sequence of occurrence for your triggers.
What Is Recursion?
Consider a scenario where you have written an update code on a contact object whenever its parent account gets updated. To achieve this you are using the update trigger of account (Suppose trigger A) and updating your contacts.
How to Avoid
In order to avoid this situation, we will go to a static variable. As we know static variables can be initialized only once. We will use this feature to avoid recursion in our code.
Best practice for triggers
One trigger per object so you don't have to think about the execution order as there is no control over which trigger would be executed first.
Apex Trigger
Trigger feedback on contact (after update) { if (!checkRecursive.firstcall) { checkRecursive.firstcall = true; Id conId; for (contact c:trigger.new) { conId=c.Id; } Contact con= [select id, name from contact where id!=:conId limit 1]; con.email=‘[email protected]’; Update con; }} Static in Salesforce are per transaction, so the value will be true only for the current transaction.
