Oracle PLSQL Tutorial 42- Before and After Trigger in PLSQL

In this Video, We are explaining about Before and After Trigger in PLSQL with Example. What is Before Trigger? Data Validation: Before inserting an employee record, a trigger can check if the salary entered is within the valid range for their position. Setting Default Values: Before inserting an employee record, a trigger can automatically set the employee joining date to the current date and time. Preventing Invalid Data: Before deleting a employee record, a trigger can check if the employee has any dues and prevent the deletion if they do. What is After Trigger? Auditing: After an employee record is updated, a trigger can log the changes made to an audit table. Notifications: After a new employee is joined, a trigger can send an email notification to the manager and the other department. Updating Related Tables: After a employee salary is updated, a trigger can update the SALARY in related tables like HIKE. Advantages of Before and After Triggers Data Integrity: Enforce business rules and constraints to ensure data accuracy and consistency. Automation: Automate tasks that would otherwise require manual intervention, saving time and effort. Improved Security: Prevent unauthorized data modifications and enhance the overall security of the database. Some other Video related to PL SQL tutorial.
