![]() This was taken care by setting the product_id column as the Identity Column). 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. Use this CREATE EXTERNAL DATA SOURCE command to store the location of the data, and the type of data.In this tutorial, you’ll see the complete steps to create a table in SQL Server. You may need to adjust some of the values. To get started, create a SQL file named createDBimportCSV.sql and add the following code. You will be importing Excel data to SQL Server. For this tutorial, you can download this employee sample data to follow along. CREDENTIAL: Provide the credential created in the previous step. This script will create a database and a table, then import CSV data to the database. LOCATION: Provide Azure storage account name and blob container name. C: Create an external data source - TYPE: HADOOP - PolyBase uses Hadoop APIs to access data in Azure blob storage. CREATE DATABASE SCOPED CREDENTIAL AzureStorageCredential SECRET: Provide your Azure storage account key. B: Create a database scoped credential - IDENTITY: Provide any string, it is not used for authentication to Azure storage. Required to encrypt the credential secret in the next step. Only necessary if one does not already exist. It then creates and uses a database-scoped credential to define the external data source. This script shows how to create a master key for the database. If you are using this tutorial as a guide for importing your own data, you need to secure access to the data. You don't need secure access to the data since it is already accessible to anyone. Skip this step if you are using the tutorial to load the Contoso data. The external object definitions are stored in SQL Data Warehouse. PolyBase uses T-SQL external objects to define the location and attributes of the external data. If you don't already have this, see Create a SQL Data Warehouse. To run this tutorial, you need an Azure account that already has a SQL Data Warehouse database. Perform optimizations after the load is finished.Configure PolyBase for loading from a public blob storage container.Use PolyBase to load public data from Azure blob storage into the Contoso Retail Data Warehouse schema. Use PolyBase to load public Contoso Retail Data Warehouse data into Azure SQL Data Warehouse
