Executing Stored Procedures

What is this?
From C#, set CommandType.StoredProcedure and CommandText to the procedure name — then add parameters.
Why should you care?
This is how ShopNest APIs invoke ERP/banking procedures.
See it live — copy this example
Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.
await using var cmd = new SqlCommand("usp_Orders_GetByCustomer", conn)
{
CommandType = CommandType.StoredProcedure
};
cmd.Parameters.Add("@CustomerId", SqlDbType.Int).Value = 7;
await using var reader = await cmd.ExecuteReaderAsync(ct);
while (await reader.ReadAsync(ct))
Console.WriteLine(reader.GetInt32(0));What happened?
- No EXEC prefix in CommandText.
- Parameter names match @names.
- Use reader/NonQuery/Scalar as needed.
Practice next
- Call GetByCustomer.
- Compare to raw SQL call.
- Check plan cache reuse.
- Call GetPending with no params.
- Time two calls.
Remember
CommandType.StoredProcedure. Match @names. Pick Execute*.
ShopNest API → usp_
Controller → repo → stored procedure.
Outcome: Legacy SQL reachable from modern API.
