How do you stop a recursive trigger?
Best practice for triggers: Logic-less Triggers – use Helper classes to handle logic. Code coverage 100% 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 solve a recursive trigger?
How to avoid Recursive Trigger: To avoid recursive triggers you can create a class with a static Boolean variable with default value true. In the trigger, before executing your code keep a check that the variable is true or not. Once you check make the variable false.
What is recursion in Apex?
A recursive method is nothing more than a method that calls itself. Anytime a method is called it goes on the top of something known as the call stack. Methods are executed from the top of the calls stack to the bottom. In the case of Apex we have limit to our stack depth of 1000.
What is a recursive trigger and how to avoid it?
A recursive trigger is one that performs an action, such as an update or insert, which invokes itself owing to, say something like an update it performs. eg in a before trigger, if you select some records and update them, the trigger will invoke itself. To avoid, static variable ‘locks’ are used.
When does the recursion stop in Salesforce trigger?
With this approach in place the recursion stops once the trigger is called a second time, as it does not attempt to insert a third record. The result is for every one record a second additional record is created and the recursion is avoided. thanks. Avoiding Recursive Triggers:
How are static variables defined in a trigger?
Static variables defined in a trigger don’t retain their values between different trigger contexts within the same transaction, for example, between before insert and after insert invocations. Define the static variables in a class instead so that the trigger can access these class member variables and check their static values.
