Hi Guys,

I am facing a problem, "select * from empdetails" working fine but "select empName from empdetails where empId='sumit' and password='12345'" it takes much more time and after that gives exception message "ExecuterReader requires an open and available Connection. The Connection's current state is closed."

i fire these command on web server( on my local pc both command working fine).

Please help me.

Thank you in advance!

Before ExecuteReader()

try this

sqlconnection.Open();

SqlConnection con = new SqlConnection("Server=(local)\\SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=SSPI");

SqlCommand cmd = new SqlCommand();

cmd.CommandText = "SELECT EmployeeID, FirstName + ' ' + LastName as FullName FROM Employees";

cmd.Connection = con;

C#

if (con.State == System.Data.ConnectionState.Open)
        {
            con.Close();
        }

con.Open();

SqlDataReader reader = cmd.ExecuteReader();

while (reader.Read()) {

}

reader.Close();
con.Close();
