Create tables in the warehouse

Applies to: ✅ Warehouse in Microsoft Fabric

This article provides two examples that show how to create a new table in Fabric Data Warehouse, from a parquet file or through the warehouse editor in the Fabric portal.

Prerequisites

To get started, you must complete the following prerequisites:

  • Have access to a Warehouse item within a Premium capacity workspace with contributor or higher permissions.
    • Be sure to connect to your warehouse item. You cannot create tables directly in the SQL analytics endpoint of a warehouse.
  • Choose your query tool. This tutorial features the SQL query editor in the Microsoft Fabric portal, but you can use any T-SQL querying tool.

For more information on connecting to your Warehouse in Microsoft Fabric, see Connectivity.

Create a blank table in the SQL query editor with templates

  1. In the warehouse editor ribbon, locate the SQL templates dropdown list.

  2. Select New table, and an autogenerated CREATE TABLE script template appears in your new SQL query window.

  3. Update the table name and column definitions in the CREATE TABLE template to match the structure you need. Your T-SQL script should look similar to the following code:

    CREATE TABLE [dbo].[bing_covid]
(
    id                int,
    updated           date,
    confirmed         int,
    confirmed_change  int,
    deaths            int,
    deaths_change     int,
    recovered         int,
    recovered_change  int,
    latitude          float,
    longitude         float,
    iso2              varchar(2),
    iso3              varchar(3),
    country_region    varchar(60),
    admin_region_1    varchar(60),
    iso_subdivision   varchar(30),
    admin_region_2    varchar(60),
    load_time         datetime2(6)
);

  4. Select Run to create the table.

Create a loaded table in the SQL query editor from an external file

You can also create a table directly from an external parquet file that you have access to. In this example, we'll create a new table based on a publicly available data file. In the query editor, paste and run the following T-SQL code:

CREATE TABLE dbo.bing_covid AS
SELECT *
FROM OPENROWSET(BULK 'https://pandemicdatalake.blob.core.windows.net/public/curated/covid-19/bing_covid-19_data/latest/bing_covid-19_data.parquet');

The CTAS (Create Table As Select) statement creates a new table and populates it with data retrieved from the specified source file, streamlining the process of both defining and loading the table in a single step. You can find more ingestion options in Ingest data with T-SQL page.
