Howto Insert A Null DateTime Into A Sql Server 2005 Database

Apr 2, 2008

I'm importing data form an Excel file to a Sql Server Database. Some of the data imported represents time as a double type so i convert the times into DateTime to be inserted into the database. The time values that aren't available in the Excel file are 0.. so what i want to do is insert null into the database for all the values that are 0 in the excel file... How do i do that based on this code i have so far:protected void ButtonImport_Click(object sender, EventArgs e){PanelUpload.Visible = false;PanelView.Visible = false;PanelImport.Visible = true;LabelImport.Text = "";OleDbCommand objCommand = new OleDbCommand();objCommand = ExcelConnection(); OleDbDataReader reader;reader = objCommand.ExecuteReader(); while (reader.Read()){DateTime? in_1 = null;DateTime? out_1 = null;DateTime? in_2 = null;DateTime? out_2 = null; int emp_id = Convert.ToInt32(reader["emp_id"]);DateTime date_entry = Convert.ToDateTime(reader["date_entry"]);if (Convert.ToDouble(reader["in_1"]) != 0)in_1 = ConvertDoubleToDateTime((double)reader["in_1"]);if (Convert.ToDouble(reader["out_1"]) != 0)out_1 = ConvertDoubleToDateTime((double)reader["out_1"]);if (Convert.ToDouble(reader["in_2"]) != 0)in_2 = ConvertDoubleToDateTime((double)reader["in_2"]);if (Convert.ToDouble(reader["out_2"]) != 0)out_2 = ConvertDoubleToDateTime((double)reader["out_2"]); ImportIntoAttendance(emp_id, date_entry, in_1, out_1, in_2, out_2);} reader.Close();}protected void ImportIntoAttendance(int emp_id, DateTime date_entry, DateTime? in_1, DateTime? out_1, DateTime? in_2, DateTime? out_2){ SqlDataSource AttendanceDataSource = new SqlDataSource();AttendanceDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["SalariesConnectionString1"].ToString();AttendanceDataSource.InsertCommandType = SqlDataSourceCommandType.Text;AttendanceDataSource.InsertCommand = "INSERT INTO Attendance (emp_id, date_entry, in_1, out_1, in_2, out_2) " +"VALUES ('" + emp_id + "', '" + date_entry + "', '" + in_1 + "', '" + out_1 + "', " +"'" + in_2 + "', '" + out_2 + "')"; int rowsAffected = 0;try{rowsAffected = AttendanceDataSource.Insert();}catch(Exception ex){LabelImport.Text += "" + ex + " ";} }private DateTime ConvertDoubleToDateTime(double dbTime){string[] SplitTime = dbTime.ToString().Split('.');string hours = SplitTime[0];string minutes = String.Empty;string time = String.Empty; if (dbTime.ToString().IndexOf('.') != -1){if (SplitTime[1].Length >= 1){if (SplitTime[1].Length == 1)minutes = Convert.ToString(Convert.ToDouble(SplitTime[1]) * 10);else if (SplitTime[1].Length > 1)minutes = SplitTime[1];}}elseminutes = "00";time = hours + ":" + minutes;return Convert.ToDateTime(time);}

Problem Unicode Data 0x2300 In SQLServer 2000 SQLServer 2005 Express

Sep 20, 2006

Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))

Insert Data
insert into testunicode (Bez)values('��')
with 2 Unicode characters
�� = 0x2300
�� = 0x2122

Selecting the data
select Bez from testunicode
I see
"?��"

�� = 0x2122 is ok but instead of 0x2300 there is 0x3f

When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'��')

and select again voila i see
"��"
Does anyone have an idea?

Thanks
