Detailed explanation of sql trigger operation

Triggers are special stored procedures that are automatically executed when inserting, updating, or deleting a table. Triggers are generally used on constraints with more complex check constraints. The difference between triggers and ordinary stored procedures is that triggers operate on a certain table. During operations such as update, insert, and delete, the system will automatically call and execute the corresponding trigger on the table. Triggers in SQL Server 2005 can be divided into two categories: DML triggers and DDL triggers. DDL triggers affect a variety of data definition language statements and are triggered. These statements include create, alter, and drop statements.

SQL summary trigger

A trigger is a special type of stored procedure that is not called directly by the user. When you create a trigger, you define it to execute when a specific type of data modification is made to a specific table or column. Triggers can query other tables and can contain complex SQL statements. They are primarily used to enforce compliance with complex business rules or requirements. For example, you can control whether new orders are allowed to be inserted based on the customer's current account status. Triggers can also be used to enforce referential integrity so that when rows are added, updated, or deleted in multiple tables, the relationships defined between the tables are preserved.

Detailed explanation of triggers in SQL

A trigger is a special stored procedure. Its execution is not called by a program or started manually, but is triggered by an event. When a table is operated (insert, delete, update), its execution will be activated. , Triggers are often used to strengthen data integrity constraints and business rules. In my opinion, a trigger is actually an event, just like in C#, clicking a button will trigger the corresponding operation.
