How to Delete a Trigger in MariaDB?

The DROP TRIGGER statement is used to delete unwanted triggers in the table of the database. We may also add the IF EXISTS conditional operator to check if the trigger already exists to prevent potential error if the trigger does not exist.

The database name can also be provided along with the table name. The statement can run only if the user has permission and there are no effects.

Let’s set up an Environment to Perform Drop Triggers Operation

To understand How to Delete a Trigger in MariaDB we need a table on which we will perform various operations and queries. Here we will consider a table called customers which contains id, name, email, phone_number, and active as Columns.

CREATE TABLE customers (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL,
  email VARCHAR(255) UNIQUE NOT NULL,
  phone_number VARCHAR(20),
  active BOOLEAN DEFAULT TRUE
);

Output:

Explanation: The query creates a table named as customers with id, name, email, phone_number and active columns with their respective constraints.

In a database management system(DBMS), triggers are essential for automating actions based on specific events. However, there are times when certain triggers need to be removed or dropped from the database.

In MariaDB, the DROP TRIGGER statement provides a straightforward way to achieve this task. In this article, we’ll explore what is DROP triggers and how to use DROP triggers by understanding various examples and so on.
