What constraint does Snowflake enforce?

All constraints
Only NOT NULL constraints
Primary Key constraints
Foreign Key constraints

The correct answer is: Only NOT NULL constraints

Snowflake enforces the NOT NULL constraint, which ensures that a column cannot contain NULL values. This behavior is significant because it maintains data integrity by preventing incomplete or missing data from being entered into the database. While Snowflake supports the definitions of other types of constraints, it does not actively enforce them the way traditional relational databases do. For instance, primary key and foreign key constraints are recognized by Snowflake and can be defined, but they are not enforced within the database environment—meaning that the database does not prevent duplicate entries or orphaned records as a result of these constraints. Therefore, only the NOT NULL constraint is actively preserved by Snowflake, making it a fundamental aspect of ensuring data quality within its tables. Understanding that other constraints exist in a defined capacity but are not enforced is key in managing and designing databases within Snowflake effectively.
