You can find detailed explanation of the trigger functionality and syntax in this article.

The main requirement for running such MySQL Triggers is having MySQL SUPERUSER privileges.

Such privileges can be granted on the VPS and Dedicated Servers. Granting SUPERUSER MySQL privileges to a user hosted on a Shared Server is not possible due to our server setup.

Here is an example of a MySQL trigger:

  • First we will create the table for which the trigger will be set via SSH:
  • Next we will define the trigger. It will be executed before every INSERT statement for the people table:
  • We will insert two records to check the trigger functionality.
  • At the end we will check the result.
