In this blog we will know how to display Intime and Outtime of employee in a Gridview.Suppose we have a table named as employee which contains four columns as empCode, inoutMode, date and time. In time column we have both the Intime and Outtime of the employee respectively. So, here our work is to display both the Intime and Outtime separately of the respective employees into a Gridview.

The scenario is

Create table employee (empCode varchar(50),inoutMode int,date varchar(50),time varchar(50))

employee table data

empCode inoutMode date time

6001 0 16/09/2011 09:05:34

6002 0 16/09/2011 09:33:13

6001 1 16/09/2011 18:05:09

6002 1 16/09/2011 17:44:34

I need the output as below

empCode date Intime Outtime

6001 16/09/2011 09:05:34 18:05:09

6002 16/09/2011 09:33:13 17:44:34

str = "SELECT a.empCode,a.date,a.[time] AS Intime,b.Outtime FROM employee A LEFT JOIN ( SELECT empCode,date,[time] AS Outtime FROM employee WHERE employee.inoutMode = 1 ) b ON a.empCode = b.empCode AND a.date = b.date WHERE a.inoutMode = 0";

com = new SqlCommand(str, con);

SqlDataReader reader = com.ExecuteReader();

GridView1.DataSource = reader;

GridView1.DataBind();

con.Close();

}
