Final answer:
In the CREATE command of a database programming language, constraints cannot be directly assigned to a table.
Step-by-step explanation:
In the CREATE command of a database programming language, such as SQL, you are not allowed to assign integrity, referential, or any other constraints directly on a table. Constraints are typically defined separately using the ALTER TABLE command after the table has already been created.
For example, if you want to add a constraint to enforce referential integrity between two tables, you would use the ALTER TABLE command with the ADD CONSTRAINT clause.
Assigning constraints in this manner allows for more flexibility, as it allows you to modify the constraints without having to recreate the entire table. This can be especially useful when dealing with large and complex databases.
