Question

I’m using SQL Server 2008 and my fields have DATE type but in Visual Studio in my program when I read may data it shows me DATE & TIME what should I do? I try to cast my fields in SELECT query of my program but it gives me some error,how can I solve this problem?

This is my behind code:

     protected void Page_Load(object sender, EventArgs e)
        {
                SqlCommand cmd = new SqlCommand();
                cmd.Connection = new SqlConnection(Class1.CnnStr);
                SqlDataReader reader;


                cmd.CommandText = "select ContractStartDate,MandateValidDate from table where BrokerName=@BrokerName";
                cmd.Connection.Open();
                cmd.Parameters.AddWithValue("@BrokerName", BrokerName_txt.Text);
                reader = cmd.ExecuteReader();

                if (reader.Read())
                {


                    ContractStartDate_txt.Text = Convert.ToDateTime(reader["ContractStartDate"]).ToString("dd/MM/yyyy");
                    MandateValidDate_txt.Text = Convert.ToDateTime(reader["MandateValidDate"]).ToString("dd/MM/yyyy");               
                    reader.Close();
                }
                cmd.Connection.Close();

            }

and because I want to save data after read them it gives me error:

Conversion failed when converting date and/or time from character string.

Answer 1

You use Convert.ToDateTime() to convert the strings returned from the database first, later by using DateTime.ToString(“dd/MM/yyyy”) you can get only Date value from the Date & Time.

ContractStartDate_txt.Text = Convert.ToDateTime(reader["ContractStartDate"]).ToString("dd/MM/yyyy");
MandateValidDate_txt.Text = Convert.ToDateTime(reader["MandateValidDate"]).ToString("dd/MM/yyyy");
