The Difference Between a Trigger and a Stored Procedure in Oracle Database
In Oracle database, the main difference between a trigger and a stored procedure lies in their execution mechanisms and purposes.
Focus Keyword: Oracle database
Triggers:
A trigger is a database object that automatically executes a set of actions in response to specific events, such as insert, update, or delete operations on a table. Triggers are often used to enforce complex business rules or maintain data integrity through automated actions.
Stored Procedures:
On the other hand, a stored procedure is a predefined set of SQL statements that are stored and can be called to perform a specific task or set of tasks in the Oracle database. Stored procedures are explicitly invoked by application programs or other stored procedures to perform operations.
While both triggers and stored procedures offer ways to automate tasks in Oracle database, triggers are event-driven and execute automatically upon predefined events, whereas stored procedures are explicitly called and executed by client applications or other procedures.
In summary, triggers are reactive mechanisms in Oracle database that respond to specific data modification events, while stored procedures are proactive entities that encapsulate a set of operations for manual invocation.
