Stored Procedure in Fabric Warehouse – Input & Output Parameters SQL Demo

In this Microsoft Fabric tutorial, you'll learn how to create and execute a stored procedure with input and output parameters. This is especially useful when you want to encapsulate query logic and reuse it across reports, data pipelines, and dashboards.

🧠 What is a Stored Procedure?

A stored procedure is a reusable set of SQL statements saved in the database. It can take input parameters, return output values, and perform operations like reading or modifying data.

✅ Benefits of Stored Procedures:

Encapsulates business logic
Promotes reuse and consistency
Supports input and output parameters
Can include conditional and complex logic

🏗️ Step 1: Create a Sample Table

CREATE TABLE dbo.Orders (
    OrderID INT,
    CustomerName VARCHAR(100),
    OrderAmount DECIMAL(10,2)
);

💾 Step 2: Insert Sample Data

INSERT INTO dbo.Orders VALUES
(1, 'Aamir', 500.00),
(2, 'Sara', 750.00),
(3, 'John', 1200.00);

⚙️ Step 3: Create the Stored Procedure

This procedure accepts a customer name as input and returns the total order amount as output:

ALTER PROCEDURE dbo.GetCustomerTotalOrders
    @CustomerName VARCHAR(100),
    @TotalAmount DECIMAL(10,2) OUTPUT
AS
BEGIN
    SELECT @TotalAmount = SUM(OrderAmount)
    FROM dbo.Orders
    WHERE CustomerName = @CustomerName;
END;

🚀 Step 4: Execute the Stored Procedure

-- Declare output variable
DECLARE @Total DECIMAL(10,2);

-- Execute with input and capture output
EXEC dbo.GetCustomerTotalOrders
    @CustomerName = 'Aamir',
    @TotalAmount = @Total OUTPUT;

-- Display the result
SELECT 'Total Order Amount for Aamir' AS Description, @Total AS TotalAmount;

🧹 Optional Cleanup

-- DROP PROCEDURE dbo.GetCustomerTotalOrders;
-- DROP TABLE dbo.Orders;
