shikher jain I created two custom classes class and student. I want to create a trigger for updating some values and delete related students
trigger CustomStatusChanged on Class__c (before update) {
for(Class__c cls : trigger.new){
if(cls.Custom_Status__c == 'Reset'){
delete [Select Name from Student__c where Class_object__c in :trigger.new];
}
}
}
I have written this code but got self reference error
for(Class__c cls : trigger.new){
if(cls.Custom_Status__c == 'Reset'){
delete [Select Name from Student__c where Class_object__c in :trigger.new];
}
}
}

Generally, soql queries inside a loop is not considered as a best practice that is why I was suggesting the above method.
As your implementation could change this was one way I thought this can be implemented.

I hope this helps.

Can you try putting the necessary records in a list and then delete do a DML operation after the loop, let me know if this works and you are doing a soql for every value is an iteration in the trigger.new can you try minimizing it by adding the classes id or such to a set then get the student records that match it and then delete them after the loop.
Do let me know if this helps and in case if it does can you mark this as the best answer so that it can be used by others in the future.
