Copy Data from one table to another Table using Windows Service in C#

In this article I have described, how to copy data from one table to another table using windows service with the help of timer control in C#.  Data copy from one table to another table after a certain intervals of times (intervals are feature of Timer Control). Below I have described all steps (Creating windows service, installing/uninstalling windows services, using of timer control etc.).Creating Windows Service

Step 1: Open visual studio and select windows service application as below image. For demonstration I have used Visual Studio 2010 with 4.0 frameworks and SQL Server 2008. If you like to use another framework version, don’t worry, follow the same step.

1.       Click on Windows tag.

2.       Select Windows Service option.

3.       Give the name of application. Here I have given name “WindowsServiceDemo”of my application.

4.       Press button “OK” and move next steps;

Step 2: When you press button OK, you see as below window.

Step 3: Open “Service1.cs” as below. This .cs file contain two method “OnStart()” and “OnStop()”. These two methods used for start and stop windows service.

Step 4: For demonstration first we create two tables and put some data into first table. Use below SQL query for creating table and inserting data.

CREATE DATABASE WindowsServiceDemo

GO

 

USE WindowsServiceDemo

GO

 

CREATE TABLE [dbo].[EmployeeStatus]

(

[EmpID] INT IDENTITY PRIMARY KEY,

[EmpName] VARCHAR(50) NOT NULL,

[IsActive] BIT NOT NULL

)

GO

 

CREATE TABLE [dbo].[xEmployeeStatus]

(

[SNo] INT IDENTITY PRIMARY KEY,

[EmpID] INT NOT NULL,

[EmpName] VARCHAR(50) NOT NULL

)

GO

 

INSERT [dbo].[EmployeeStatus]([EmpName],[IsActive]) VALUES('Mark Alderson','True'), ('Arnold','False'), ('Jems','False')

 

Check your table, my table as below Image.

Note: See above image, “IsActive” column (in red rectangular) have true (1) and false (0) value. In the next steps I have described how to copy rows from “EmployeeStatus” table which column (IsActive) values are false and paste into “xEmployeeStatus” table. If data transfer successfully then false status become true of “EmployeeStatus” table.

Step 5:  Add “System.Timers” namespace and write below code, before OnStart() method.

Timer timer1 = new Timer();

 

Write below code within “OnStart()” method (Step 3).

timer1.Elapsed += new ElapsedEventHandler(timer1_Elapsed);

            timer1.Interval = 10000;

            timer1.Enabled = true;

            timer1.Start();

 

Note: 10000 millisecond = 10 Seconds. You can change timer intervals according your requirement.

Step 6:  Now, write below code within OnStop() method.

timer1.Enabled = false;

 

Step 7: Used below line of code for creating “timer1_Elapsed” event.

private void timer1_Elapsed(object sender, EventArgs e)

        {

            SqlConnection con = new SqlConnection("Data Source =  Your database service name; Initial Catalog = WindowsServiceDemo; User Id=  sa;  Password= password;");

            SqlCommand cmd1;

            SqlCommand cmd2;

            SqlDataAdapter adap = new SqlDataAdapter("Select [EmpID],[EmpName] From [dbo].[EmployeeStatus] Where [IsActive]='False'", con);

            DataTable dt = new DataTable();

            adap.Fill(dt);

            con.Open();

            foreach (DataRow dr in dt.Rows)

            {

 

                cmd1 = new SqlCommand("Insert into [dbo].[xEmployeeStatus]([EmpID],[EmpName]) values('" + dr[0].ToString() + "','" + dr[1].ToString() + "')", con);

                if (cmd1.ExecuteNonQuery() > 0)

                {

                    cmd2 = new SqlCommand("Update [dbo].[EmployeeStatus] Set [IsActive] = 'True' Where [IsActive]='False'", con);

                    int i = cmd2.ExecuteNonQuery();

                }

            }

            con.Close();

            dt.Dispose();

            adap.Dispose();

        }

 

Note: Used “System.Data” and “System.Data.SqlClient” namespace and remove unnecessary namespaces.   You can see complete line of code which described below.

using System;

using System.Data;

using System.ServiceProcess;

using System.Timers;

using System.Data.SqlClient;

 

namespace WindowsServiceDemo

{

    public partial class Service1 : ServiceBase

    {

        public Service1()

        {

            InitializeComponent();

        }

 

        Timer timer1 = new Timer();

 

        protected override void OnStart(string[] args)

        {

            timer1.Elapsed += new ElapsedEventHandler(timer1_Elapsed);

            timer1.Interval = 10000;

            timer1.Enabled = true;

            timer1.Start();

        }

 

        protected override void OnStop()

        {

            timer1.Enabled = false;

        }

 

        private void timer1_Elapsed(object sender, EventArgs e)

        {

            SqlConnection con = new SqlConnection("Data Source =  Your database service name; Initial Catalog = WindowsServiceDemo; User Id=  server ; Password= password;");

            SqlCommand cmd1;

            SqlCommand cmd2;

            SqlDataAdapter adap = new SqlDataAdapter("Select [EmpID],[EmpName] From [dbo].[EmployeeStatus] Where [IsActive]='False'", con);

            DataTable dt = new DataTable();

            adap.Fill(dt);

            con.Open();

            foreach (DataRow dr in dt.Rows)

            {

 

                cmd1 = new SqlCommand("Insert into [dbo].[xEmployeeStatus]([EmpID],[EmpName]) values('" + dr[0].ToString() + "','" + dr[1].ToString() + "')", con);

                if (cmd1.ExecuteNonQuery() > 0)

                {

                    cmd2 = new SqlCommand("Update [dbo].[EmployeeStatus] Set [IsActive] = 'True' Where [IsActive]='False'", con);

                    int i = cmd2.ExecuteNonQuery();

                }

            }

            con.Close();

            dt.Dispose();

            adap.Dispose();

        }

    }

}

 

Step 7: Save and build application. In next steps I tell you how to install web service. Now double click on “Service1.cs” note (red circle in below image).
