Packages, INSTEAD OF and triggers
Packages and triggers are two distinct features in PL/SQL, with different purposes and use cases.
Packages are a way to organize and encapsulate related functions, procedures, and variables into a single unit. They allow you to group related code together and provide a level of abstraction that makes it easier to manage and maintain your code. Packages can be used to create reusable code libraries that can be shared across multiple programs, reducing duplication and improving code consistency.
Triggers, on the other hand, are a type of stored procedure that is automatically executed in response to specific events or changes to a database. Triggers can be used to enforce business rules, maintain data integrity, and automate certain tasks. For example, you could create a trigger that automatically updates a record in a database whenever a related record is modified.
While both packages and triggers can be useful tools in a PL/SQL developer’s toolkit, they serve different purposes and are used in different contexts. Packages are typically used for organizing and reusing code, while triggers are used for automating database operations and enforcing data consistency.
