Design and Implementation of Trigger Based on MySQL Database Linkage Execution
Triggers are typically associated with INSERT,UPDATE and DELETE statements,allowing users to execute custom SQL statements before and after these operations.For complex tables in a database,it is necessary to ensure the consistency and integrity of the data in the tables.In the database,triggers can be defined according to business rules,and changes of data in multiple interrelated tables can be controlled to prevent data changes that do not comply with business rules,thereby improving the maintainability and data integrity of the database.This automated linkage process helps reduce human errors and improve data processing efficiency.
