![]() The production.products table stores the product’s information such as name, brand, category, model year, and list price.Įach product belongs to a brand specified by the brand_id column. ) Code language: SQL (Structured Query Language) ( sql ) Table production.products CREATE TABLE production.brands (īrand_id INT IDENTITY ( 1, 1) PRIMARY KEY, The production.brands table stores the brand’s information of bikes, for example, Electra, Haro, and Heller. ) Code language: SQL (Structured Query Language) ( sql ) Table production.brands CREATE TABLE production.categories (Ĭategory_id INT IDENTITY ( 1, 1) PRIMARY KEY, The production.categories table stores the bike’s categories such as children bicycles, comfort bicycles, and electric bikes. ) Code language: SQL (Structured Query Language) ( sql ) Table production.categories Staff_id INT IDENTITY ( 1, 1) PRIMARY KEY, If a staff no longer works for any stores, the value in the active column is set to zero. If the value in the manager_id is null, then the staff is the top manager. A store can have one or more staffs.Ī staff reports to a store manager specified by the value in the manager_id column. It also contains the communication information such as email and phone.Ī staff works at a store specified by the value in the store_id column. The sales.staffs table stores the essential information of staffs including first name, last name. ) Code language: SQL (Structured Query Language) ( sql ) Table sales.staffs Store_id INT IDENTITY ( 1, 1) PRIMARY KEY, Each store has a store name, contact information such as phone and email, and an address including street, city, state, and zip code. The sales.stores table includes the store’s information. The following illustrates the BikeStores database diagram:Īs you can see from the diagram, the BikeStores sample database has two schemas sales and production, and these schemas have nine tables. This was taken care by setting the product_id column as the Identity Column).Summary: in this tutorial, you’ll learn about the SQL Server sample database called BikeStores. You can then add records to the table by running this INSERT INTO query: INSERT INTO products (product_name, price)ĥ new records will be inserted into the table (notice that it wasn’t necessary to populate the product_id column using the insert query. Product_id int identity(1,1) primary key, Then, recreate the table using the CREATE TABLE query: CREATE TABLE products ( You can drop the ‘products’ table using the query below: DROP TABLE products ![]() To begin, drop the ‘products’ table in order to start from scratch. Let’s now recreate this table with the use of queries. This is how the new ‘ products‘ table should look like: product_id Where the product_id column will be selected as the Primary Key as well as the Identity Column. Let’s say that you want to create a table with a Primary Key and Identity Column.įor example, suppose that you want to recreate the ‘ products‘ table with the following 3 columns: ![]() You should then get the results below: product_nameĬreate a Table in SQL Server with Primary Key and Identity ColumnĪ Primary Key uniquely identifies each record (i.e., row) in your table, while an Identity Column ensures that an auto-increment is applied to your column whenever a new record is inserted into the table. Step 4: Verify that the values were inserted into the tableįinally, run the following SELECT query to verify that the values were inserted into the table: SELECT * FROM products You can insert values into the table using an INSERT INTO query: INSERT INTO products (product_name, price) ![]() Let’s now add the following values into the ‘products’ table: product_name You can then create the table using the following CREATE TABLE query under your database: CREATE TABLE products ( Where the data type for the ‘ product_name‘ column would be nvarchar(50), while the data type for the ‘ price‘ column would be int (for integers). The table should store the following data: product_name Next, create a table under your database.įor instance, let’s create a table called ‘ products‘ which contains 2 columns: For example, you may use the following query to create a database called the test_database: CREATE DATABASE test_database If you haven’t already done so, create a database where the table will be stored. Steps to Create a Table in SQL Server Step 1: Create a database ![]() An example is also reviewed for demonstration purposes. In this tutorial, you’ll see the complete steps to create a table in SQL Server. ![]()
