What is Salesforce Trigger

Salesforce Trigger:-

Salesforce trigger is apex code that executes before or after the folowing types of operations.
  • insert    -  You can have this trigger run  before or after objects records are inserted into database.
  • update  -  You can have this trigger run  before or after objects records are updated into database.
  • delete   -  You can have this trigger run  before or after objects records are deleted from  database.
  • merge   -  Merge events do not fire their own trigger events. Instead, they fire delete and update event
  • upsert   -  Fire both before and after insert or before and after update triggers as  appropriate
  • undelete- record is restored from the Recycle Bin 


I will be explaining each trigger with example in next tutorial.
