This should hopefully be a simple one. When using a date time picker in a windows form, I want an SQL statement to be carried out, like so:

string sql = "SELECT * FROM Jobs WHERE JobDate = '" + dtpJobDate.Text + "'";

Unfortunately, this doesn't actually provide any results because the JobDate field is stored as a DateTime value. I'd like to be able to search for all records that are on this date, no matter what the time stored may be, any help?

New query:

        SqlDataAdapter da2 = new SqlDataAdapter();
        SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "SELECT * FROM Jobs WHERE JobDate >= @p_StartDate AND JobDate < @p_EndDate";
        cmd.Parameters.Add ("@p_StartDate", SqlDbType.DateTime).Value = dtpJobDate.Value.Date;
        cmd.Parameters.Add ("@p_EndDate", SqlDbType.DateTime).Value = dtpJobDate.Value.Date.AddDays(1);
        cmd.Connection = conn;
        da2.SelectCommand = cmd;
        da2.Fill(dt);
        dgvJobDiary.DataSource = dt;

Huge thanks for all the help!
