C#: Sql Stored Procedure

Purpose: – Illustrates using Sql Stored Procedure with SqlDataReader.
Prerequistes:

1. Install C# (Express or Standard Edition)
2. Install SQL Server Express
3. Download Northwind Database
4. Attach Northwind Database to Databases in Sql Express

Notes:

• Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
• You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Program.cs

Instructions:

1. Use C# 2008 (Express or Standard) Edition
2. Create new project; select Console Application; name of Project could be CSharp_Syntax.
3. Right-click project name in solution explorer; add new folder; name of folder could be DatabaseADONET
4. Right-click folder; add class; class name could be clsSqCalllStoredProcedure.cs
5. Copy code into clsSqlCallStoredProcedure.cs
6. Copy code into Program.cs
7. Click green arrow to start with debugging

Step 1: Use View Plain to Cut-n-paste code into clsSqlCallStoredProcedure.cs

 C# | 
 copy code |
?
 
 
using System;
using System.Data;
using System.Data.SqlClient;
 
 
public class clsSqlCallStoredProcedure
{
    static SqlConnection con;
 
    public void Main()
    {
        con = new SqlConnection("Server=(local)\\SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=SSPI");
 
        SqlCommand cmd = new SqlCommand("Sales By Year", con);
        cmd.CommandType = CommandType.StoredProcedure;
 
        // Add Parameters to Command Parameters collection
        cmd.Parameters.Add("@Beginning_Date", SqlDbType.DateTime);
        cmd.Parameters.Add("@Ending_Date", SqlDbType.DateTime);
        cmd.Parameters["@Beginning_Date"].Value = "1/1/1990";
        cmd.Parameters["@Ending_Date"].Value = "1/1/2000";
 
        try
        {
            con.Open();
            SqlDataReader reader = cmd.ExecuteReader();
            while (reader.Read())
            {
                Console.WriteLine("{0} - {1:c}", reader.GetDateTime(0), reader.GetDecimal(2));
            }
            reader.Close();
        }
        finally
        {
            con.Close();
        }
        Console.ReadLine();
 
    }
}
 
 

Step 2: Use View Plain to Cut-n-paste code into Program.cs

 C# | 
 copy code |
?
 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace CSharp_Syntax
{
    class Program
    {
        static void Main(string[] args)
        {
            //DatabaseADONET
 
            //clsSqlConnectionConnectionString mySqlConnectionConnectionString = new clsSqlConnectionConnectionString();
            //mySqlConnectionConnectionString.Main();
 
            //clsSqlSelect mySqlSelect = new clsSqlSelect();
            //mySqlSelect.Main();
 
            //clsSqlParametersInsert mySqlParametersInsert = new clsSqlParametersInsert();
            //mySqlParametersInsert.Main();
 
            clsSqlCallStoredProcedure mySqlCallStoredProcedure = new clsSqlCallStoredProcedure();
            mySqlCallStoredProcedure.Main();
 
        }
    }
}
