How do you execute a stored procedure asynchronously?

Short answer: Executing stored procedures asynchronously can improve the performance of applications by allowing other tasks to run while waiting for the procedure to finish. Example (C#): using (SqlConnection conn = new SqlConnection(connectionString))

Example code

{
await conn.OpenAsync();
using (SqlCommand cmd = new SqlCommand("GetEmployeeDetails", conn)) {
cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new SqlParameter("@emp_id", SqlDbType.Int)).Value = 101;
using (SqlDataReader reader = await cmd.ExecuteReaderAsync()) { while (await reader.ReadAsync()) { Console.WriteLine(reader["name"]); }
}
}
}

Real-world example (ShopNest)

ShopNest’s SQL Server database stores customers, products, and orders. Good indexes and clear foreign keys keep checkout queries fast and safe.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
