Description

In this course, we will talk extensively about Triggers. Triggers help us centralize table validations at the lowest level along with providing support for auditing and logging. We will take an in-depth look at how to define triggers, trigger types, row level and statement level triggers, and mutating triggers. We will take an in-depth look at both DML triggers as well as System triggers. We will talk about Compound Triggers and look at various scenarios where triggers can be useful.
