The BOOLEAN data type enables support for Ternary Logic.Adding the “ Not NULL Constraint ” to Snowflake tables can lead to inconsistency. We will perform data validation in the application layer to avoid those inconsistencies. In this blog, you will learn to add “NOT NULL Constraint”. NOT NULL Constraints will add an additional layer of data validation.Default values on columns in table definitions only get inserted when there is no explicit reference to that column in an INSERT statement.
