MAJOR ADVANDAGES OF USING SQL TRIGGERS

What is SQL Trigger


An SQL trigger is a collection of SQL statements stored in a database list. A SQL trigger is executed or deleted whenever a table-related event occurs, e.g., insert, update, or delete.

Many Website Development Company in Bangalore use SQL Triggers. The main difference between a trigger and a stored procedure is that a trigger is automatically called when a data conversion event is performed against a table, whereas the stored procedure must be invoked explicitly.
In the following sections, we will discuss the advantages and disadvantages of using SQL triggers.

Advandages of SQL Triggers


  • SQL Triggers will catch errors in business logic within the information layer
  • SQL triggers are very useful for auditing changes in data in a table.
  • It also has some business logic, so it reduces network usage and improves response time.
  • This allows some degree of data integration.
  • SQL triggers provide an alternative way to execute scheduled tasks. Triggers are automatically activated before or after a change in the data in the table.

Disadvantages of SQL Triggers


  • Not all verifications can be changed: In fact, MySQL triggers cannot change all verifications, and can only provide extended validation.
  • Not recommended for high velocity of data: Triggers are not effective for use with high-speed data, such as data when multiple events per second are high. This is because if you have high-speed data, the triggers are triggered all the time.
  • Decline in database performance: Due to the complexity of database programs, it may take longer to run and hidden performance downtime.
  • SQL triggers are invisible from client applications, and therefore, it is difficult to detect what is happening in the database layer.
