Trigger is a statement that a system executes automatically when there is any modification to the database. In a trigger, we first specify when the trigger is to be executed and then the action to be performed when the trigger executes.
Introduction to SQLTriggers A trigger is a database object that executes a piece of code, a user-defined function, or a stored procedure in response to a specific event in a table.
An SQL Trigger is a special procedure in a database that automatically executes in response to certain events, such as INSERT, UPDATE, or DELETE operations. It ensures data integrity and automates tasks.
SQLtriggers are a powerful feature that we can use to perform operations when data changes in our database automatically. In this tutorial, we’ll explore how to define and modify triggers in PostgreSQL, MySQL, and SQL Server.
Learn about Triggers in SQL Server. The trigger is a database object similar to a stored procedure that is executed automatically when an event occurs in a database.
You can create triggers directly from Transact-SQL statements or from methods of assemblies that are created in the Microsoft .NET Framework common language runtime (CLR) and uploaded to an instance of SQL Server. SQL Server lets you create multiple triggers for any specific statement.
Triggers in SQL are the statements that execute automatically at the time of change in the database. When we perform some operations like add, change and delete, a trigger occurs at that time. They are used to maintain integrity, track changes, and enforce business rules without the user's input.
Triggers in SQL are automated database actions that respond to events. Learn about their types, syntax, use cases, limitations, and best practices in SQL.
Triggers are database routines that run automatically when a specific event occurs (such as INSERT, UPDATE, or DELETE), or even in response to certain internal database events.
