Create a table named orders with columns "order_id" (int), "customer_id" (int), "order_date" (date), "total_amount" (decimal), and "status" (varchar). The table should be configured with constraints such that "order_id" and "customer_id" cannot be empty, and "order_id" serves as the primary key.
Question
Create a table named orders with columns "order_id" (int), "customer_id" (int), "order_date" (date), "total_amount" (decimal), and "status" (varchar). The table should be configured with constraints such that "order_id" and "customer_id" cannot be empty, and "order_id" serves as the primary key.
Solution
Sure, here is the SQL command to create the table as per your requirements:
CREATE TABLE orders (
order_id INT NOT NULL,
customer_id INT NOT NULL,
order_date DATE,
total_amount DECIMAL,
status VARCHAR(255),
PRIMARY KEY (order_id)
);
This command will create a table named orders with the columns order_id, customer_id, order_date, total_amount, and status. The NOT NULL constraint ensures that the order_id and customer_id columns cannot be empty. The PRIMARY KEY constraint designates order_id as the primary key of the table.
