# Create Database and Tables

Connect to your SingleStore deployment and run the following SQL commands to create a database named **tpch** and eight associated tables.

> **📝 Note**: The **SQL Editor** only runs the queries that you select, so ensure you have them all selected before selecting **Run**.
