What triggers a procedural SQL code in a database?

A procedural SQL code is typically triggered by a data manipulation event, such as an insertion, update, or deletion of records in a database. These events are essential in the context of database management, as they signify changes to the data that require specific actions to be executed automatically—actions that can include validation, updating related records, or initiating workflows.

In many relational database management systems, procedural SQL is designed to respond to these data manipulation events through mechanisms like triggers or stored procedures. When a data manipulation operation occurs, the procedural SQL code can be executed to enforce business rules, maintain data integrity, or log changes.

For instance, if a product price is updated in a sales database, a trigger might automatically adjust the pricing in related tables or log the change history. Thus, it is the occurrence of these data manipulation events that specifically activates the procedural SQL, facilitating robust and automated data management practices within the database environment.
