Introduction

Microsoft Fabric provides a robust environment for managing and transforming data within a data warehouse. One of its powerful features is the ability to create stored procedures, which allow for encapsulating SQL logic that can be reused across multiple operations. Stored procedures simplify complex queries, automate repetitive tasks, and enhance performance by reducing query execution time.

For the DP-600 certification exam, understanding how to create and use functions is essential. In this tutorial, we'll walk you through the steps to create and execute stored procedures within a Fabric warehouse.

📖 What is a Stored Procedure?

A stored procedure is a precompiled collection of SQL statements that can be executed as a single unit. Stored procedures help to encapsulate business logic, improve performance by reducing query parsing time, and enhance security by restricting direct access to underlying tables.

🌐 Why Create Stored Procedures in a Warehouse?

Stored procedures in Microsoft Fabric warehouses offer several benefits:

  • 📌 Code Reusability: Define SQL logic once and reuse it across multiple queries, reducing duplication and improving maintainability.
  • ⚡ Performance Optimization: Precompiled execution plans improve query performance, especially for complex operations.
  • 📊 Automated Data Processing: Automate repetitive tasks such as data transformation and reporting.
  • 🔄 Consistent Data Processing: Ensure uniform business rules and data transformations across queries.
  • 🛠️ Easier Maintenance: Centralize logic updates in stored procedures rather than modifying multiple queries.

💡Difference Between Stored Procedures, Views, and Functions

  • Stored Procedures: A collection of SQL statements that can include complex logic, loops, and multiple operations. They are executed with EXEC and can return multiple result sets.
  • Views: A virtual table that represents a stored query but does not allow procedural logic.
  • Functions: Return a single value or table but cannot execute multiple SQL statements like a stored procedure.

🎯 Goal

💡
Our goal is to create a stored procedure within a Fabric warehouse that creates the table student and inserts sample data, dropping the table first if it already exists.

✅ Prerequisites

Before you begin, ensure you have the following:

  • A warehouse created in your Fabric workspace.
How to create a Warehouse in Microsoft Fabric: A Step-by-Step Guide
Introduction Microsoft Fabric is a powerful All-in-One Data Platform (SaaS) in the Azure Cloud that combines various Azure components to cover the fields of Data Integration, Data Engineering, Data Science and Business Intelligence. One key component of the Microsoft Fabric architecture is the Warehouse. In this tutorial, we will explain

🔗 Step 1: Define Stored Procedure with SQL Query

First, write a SQL query to define the stored procedure. Open your Fabric warehouse and click New SQL query.

The SQL editor opens.

💡
You can rename the SQL query to give it a more meaningful name.

Let's create a stored procedure named setup_student that creates the table student and inserts sample data. To do this, enter the following T-SQL statement:
