What is this?
Stored procedures are named SQL batches saved in the database and called from ADO.NET with CommandType.StoredProcedure.

ShopNest finance still owns usp_ rules DBAs can tune without redeploying APIs.
See it live — copy this example
Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.
-- SQL
CREATE OR ALTER PROCEDURE dbo.usp_Orders_GetPending
AS
BEGIN
SET NOCOUNT ON;
SELECT Id, Total, Status FROM Orders WHERE Status = N'Pending';
ENDWhat happened?
- Procedures live in SQL Server.
- C# calls them by name.
- Plans can be reused.
Practice next
- Create usp_Orders_GetPending.
- Exec in SSMS.
- Call from C# next lessons.
- Add TOP (100).
- Filter by CustomerId parameter later.
Remember
Named SQL in DB. Call from ADO.NET. Source-control procs.
ShopNest first procedure
Pending orders exposed as usp_.
Outcome: API and SSMS share one definition.
