What are TRIGGER EVENTS in Salesforce?

In Salesforce, triggers are used to execute custom code when certain operations are performed on Salesforce records. The point at which the code runs is defined by trigger events. These events allow developers to specify when a block of code should be executed in response to specific record changes, such as insertions, updates, deletions, or undeletion.

Here are the various trigger events you can use in Salesforce:

1. Before Insert: Executes the trigger code before a new record is inserted into the database.
2. After Insert: Executes after a new record is inserted into the database.
3. Before Update: Executes before an existing record is updated.
4. After Update: Executes after an existing record is updated.
5. Before Delete: Executes before a record is deleted.
6. After Delete: Executes after a record is deleted.
7. After Undelete: Executes after a record is restored from the Recycle Bin.

For example, the following code defines a trigger for the before insert and before update events on the Account object:

trigger myAccountTrigger on Account(before insert, before update) {

    // Your code here

}

In this case, the trigger will run the defined logic before a Account record is inserted or updated, allowing you to make necessary changes or validations to the record before it's saved.

Each event is designed to handle specific operations, so choosing the right event ensures that your trigger performs the desired actions at the right moment in the record lifecycle.
