Question

Each constraint is treated as a ___________ clause of the CREATE statement.

a) SELECT
b) INSERT
c) CONSTRAINT
d) UPDATE

Answer 1

Each constraint in an SQL CREATE TABLE statement is treated as a CONSTRAINT clause. These constraints serve to maintain data integrity and are specified after column definitions within the statement.

Step-by-step explanation:

Each constraint is treated as a CONSTRAINT clause of the CREATE statement. In the context of database design and SQL, when you create a new table using the CREATE TABLE statement, constraints are used to define rules for the data in the table. They are specified after the column definitions and are preceded by the word CONSTRAINT, followed by the type of constraint, such as PRIMARY KEY, FOREIGN KEY, UNIQUE, NOT NULL, or CHECK constraint. These constraints ensure data integrity by restricting the type of data that can go into a table, enforcing relationships between tables, and maintaining the uniqueness of data.
