Problem StatementCreate a table named "products" with columns "product_id" (int), "product_name" (varchar), "description" (varchar), "unit_price" (decimal), and "available_stock" (int). Additionally, the table should have constraints such that "product_id" acts as the primary key and "product_name" is unique.The table structure is given below:Input format :No console input.Output format :The output should display a detailed description of the created 'products' table.Refer to the sample output for the column headers.Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.
Solution
To solve this problem, you need to write a SQL query to create a table named "products" with the specified columns and constraints. Here is the step-by-step solution:
Step 1: Start by writing the CREATE TABLE statement followed by the table name, which is "products" in this case.
CREATE TABLE products (
Step 2: Define the columns of the table. The data types of the columns are given in the problem statement. Also, add the NOT NULL constraint to the "product_id" and "product_name" columns to ensure that these columns always have a value.
product_id INT NOT NULL,
product_name VARCHAR(255) NOT NULL,
description VARCHAR(255),
unit_price DECIMAL(10, 2),
available_stock INT
Step 3: Define the primary key constraint on the "product_id" column and the unique constraint on the "product_name" column.
PRIMARY KEY (product_id),
UNIQUE (product_name)
Step 4: Close the parenthesis and end the statement with a semicolon.
);
So, the complete SQL query to create the "products" table is:
CREATE TABLE products (
product_id INT NOT NULL,
product_name VARCHAR(255) NOT NULL,
description VARCHAR(255),
unit_price DECIMAL(10, 2),
available_stock INT,
PRIMARY KEY (product_id),
UNIQUE (product_name)
);
This query will create a table named "products" with the specified columns and constraints. The "product_id" column is the primary key, and the "product_name" column is unique, which means it cannot have duplicate values.
