私はこのようなSQLデータを持っています
1 2m
2 3m
3 3m
6 6m
7 6m
データグリッドビューにエクスポートして表示したい。
1 2m
2 3m
3 3m
4 0m
5 0m
6 6m
7 6m
そして、ここに私のコードがあります:
private void laygio(string tenstore, string tenxuat)
{
string conn = "Data Source=USER-PC;Initial Catalog=NCKHmoi;Integrated Security=True";
SqlConnection connect = new SqlConnection(conn);
SqlCommand command = new SqlCommand();
command.Connection = connect;
connect.Open();
int stday = Convert.ToInt32(dst.Text);
int stmonth = Convert.ToInt32(mst.Text);
int styear = Convert.ToInt32(yst.Text);
int sthour = Convert.ToInt32(hst.Text);
int stminute = 0;
int stsecond = 0;
int eday = Convert.ToInt32(ded.Text);
int emonth = Convert.ToInt32(med.Text);
int eyear = Convert.ToInt32(yed.Text);
int ehour = Convert.ToInt32(hed.Text);
int eminute = 0;
int esecond = 0;
DateTime startday = new DateTime(styear, stmonth, stday, sthour, stminute, stsecond);
DateTime endday = new DateTime(eyear, emonth, eday, ehour, eminute, esecond);
DataTable tbl = new DataTable();
DataColumn Col = new DataColumn("Thời gian", typeof(int));
tbl.Columns.Add(Col);
SqlDataAdapter adapter = new SqlDataAdapter();
int i = 1;
for (DateTime xday = startday; xday <= endday; xday += TimeSpan.FromHours(1))
{
int ngay = Convert.ToInt32(xday.Day.ToString());
int thang = Convert.ToInt32(xday.Month.ToString());
int nam = Convert.ToInt32(xday.Year.ToString());
int gio = Convert.ToInt32(xday.Hour.ToString());
command.CommandType = CommandType.Text;
command.CommandText = @"Select SoLieuGio.LLNuoc from SoLieuGio where SoLieuGio.GioID= (select Gio.GioID from Gio where (Gio.Gio = @Gio and Gio.NgayID= (select Ngay.NgayID from Ngay where (Ngay.Ngay=@Ngay and Ngay.ThangID= (select Thang.ThangID from Thang where (Thang.Thang = @Thang and Thang.NamID=(select Nam.NamID from Nam where (Nam.Nam = @Nam and Nam.TramID=(select Tram.TramID from Tram Where (Tram.TenTram like @TenTram and Tram.TinhID=(select Tinh.TinhID from Tinh where (Tinh.TenTinh like @TenTinh and Tinh.KhuVucID=(select KhuVuc.KhuVucID from KhuVuc where KhuVuc.Ten=@Ten)))))))))))))";
command.Parameters.Add("@Gio", SqlDbType.BigInt).Value = gio;
command.Parameters.Add("@Ngay", SqlDbType.BigInt).Value = ngay;
command.Parameters.Add("@Thang", SqlDbType.BigInt).Value = thang;
command.Parameters.Add("@Nam", SqlDbType.BigInt).Value = nam;
command.Parameters.Add("@Ten", SqlDbType.NVarChar, 50).Value = "Đồng Bằng Bắc Bộ";
command.Parameters.Add("@TenTinh", SqlDbType.NVarChar, 50).Value = TinhComboBoxEx.Text;
command.Parameters.Add("@TenTram", SqlDbType.NVarChar, 50).Value = TramComboBoxEx.Text;
adapter.SelectCommand = command;
adapter.Fill(tbl);
dataGridView2.DataSource = tbl;
command.Parameters.Clear();
}
command.Dispose();
connect.Close();
}
そのコードの結果は次のとおりです。
1 2m 2 3m 3 3m 6 6m 7 6m
1 から 7 まで完全に表示するには、何を修正する必要がありますか。
