How many types of Teradata triggers are there?

Teradata supports two main types of triggers, which are designed to help automate processes and enforce business rules within the database. The two types are:

1. Row-Level Triggers: These triggers execute for each individual row affected by a DML (Data Manipulation Language) operation such as INSERT, UPDATE, or DELETE. They allow for fine-grained control and are useful when actions need to be taken for each row, based on specific conditions.

2. Statement-Level Triggers: In contrast, these triggers execute once for each SQL statement, regardless of the number of rows affected. This type is beneficial for actions that require a broader scope, such as logging changes or maintaining summary data.

Understanding this distinction is crucial for effective database management and ensuring that the correct trigger type is used based on the desired outcome. Being aware that there are only two types helps avoid confusion that may arise from misconceptions about the triggering mechanisms available in Teradata.
