DateTime endtime = DateTime.Now;
TimeSpan duration = endtime - starttime;
DateTime period = new DateTime(duration.Ticks);

I have the following SQL query
SELECT
[Req_ID]
,[Service_Name]
,[Req_Started_Date]
,[Task_Name]
,[Task_Status]
,[Performer_Full_Name]
[code]....
Which works fine, but what I need to calculate the total duration of a request based on the duration of the tasks completed in the request based on Req_ID. I would like to use the CASE statement I have to determine the SLA_Mins for each task and add them together to get total request SLA_Mins.
Below is the create table schema and data
GO
/****** Object: Table [dbo].[MidrangeOtherSourceControl] Script Date: 06/03/2015 18:13:15 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[MidrangeOtherSourceControl](
[Req_ID] [float] NULL,
[Service_Name] [nvarchar](255) NULL,
[code]....

Hi everyone,
I'm just using TEXTBOX control to save data into my DB. My question is, if I have multiple lines of sentences, it does not store as what it looks like. For example;
Hello, Mike
It stores into the database as "Hello, Mike" and if I read from the database, it does not have seperate lines and shows it like this;
Hello, Mike
How can I store the contents into database and make the contents as original? (Sorry for the poor English, but I hope you understand it.)

when I leave one field blank then I get the message 'can not enter null value in column X'
even when I place in the Updateparameter in my code
<asp:Parameter Name="Name" DefaultValue="" /> ASP tries to update an Null value
when i place an space as default value like

Hi
I want to know how do we store null in the database
i know Null is unkown value
but it has to be something so the SQL server can know its null ( computer only knows 0s and 1s )
is it pointers and null does not have a pointer?
or do we store something physically?
an example : we have string(varchar) column that has this value in it "Joey Tribbiani" that means in the hard disk we will see 14 bytes "Joey Tribbiani" in there, if we changed the value to "Monika" the 14 bytes will be replaced by 5 bytes "Monika", if we changed to empty strike then we will have 0 bytes ""
now if changed it to become NULL what is going to happen to the hard disk, what is going to be in there physically??
may anyone help me in this?
many thanks

Hello,
I am working on a project. We do not have a DBA, so I am performing some of these tasks.
I recently created a new database with about 10 tables. I have set up the key and primary key relationships between the data files.
How do I save the database through differenct stages of it's evolution? Suppose I populate the database, but later on decide that I we need to re-start from scratch and go back to the new database I created that is not populated. How do I save different versions of a database through it's evolution/progression?
Thanks in advance, Bill

Hi i am creating a web page which will return the results of products, the store name and the distance of the store from the postcode which the user has put into a text box. My first question is how would my database structure look, below is what it looks like at the moment;
Company; companyID, companyName, companyAddressLine1, companyAddressLine2, companyPostcode.
and
Products; productID, productName, companyID, price.
In order to achieve the proximity search how would i alter the "Company" table, as in what columns will need to be added or removed, thank you.

Hi
I have a asp:FileUpload conponent that I am trying to use to retrieve a picture file from the clients pc and store it in a SQL database.
The table is called PropertyImage and it contains the following fields:
imgID (type = int - autoincrement); imgData (type = Image); imgTitle (type = VarChar); imgType (type = VarChar); imgLength (type = BigInt);
I have a button (Button1) which when clicked calls Button1_Click()
--------------------------------------------------protected void Button1_Click(object sender, EventArgs e)
{byte[] fileData = null;
Boolean status = false;if (FileUpload1 != null)
{
// Make sure the file has data.if ((FileUpload1.PostedFile != null) && (FileUpload1.PostedFile.ContentLength > 0))
{
// Get the filename.string fn = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
try
{
// Access the file stream and begin the upload. Store the file in a memory byte array.Stream MyStream = FileUpload1.PostedFile.InputStream;
long iLength = MyStream.Length;fileData = new byte[(int)MyStream.Length];MyStream.Read(fileData, 0, (int)MyStream.Length);
MyStream.Close();
}catch (Exception ex)
{ }
}
}SqlConnection connection = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\heidihomes.mdf;Integrated Security=True;User Instance=True");
try
{
connection.Open();SqlCommand sqlCmd = new SqlCommand("INSERT INTO PropertyImage (imgData, imgaTitle, imgType, imgLength) VALUES(@data,@title,@type,@length)");
SqlParameter param = new SqlParameter();
// String connectionString = new SqlConnection(sqlCmd, connection);
param = new SqlParameter("@data", SqlDbType.Image);
param.Value = fileData;
sqlCmd.Parameters.Add(param);param = new SqlParameter("@title", SqlDbType.VarChar);
param.Value = fileData;
sqlCmd.Parameters.Add(param);param = new SqlParameter("@type", SqlDbType.VarChar);
param.Value = fileData;
sqlCmd.Parameters.Add(param);param = new SqlParameter("@length", SqlDbType.BigInt);
param.Value = fileData;
sqlCmd.Parameters.Add(param);
sqlCmd.ExecuteNonQuery();
connection.Close();status = true;
}catch (Exception ex){ }if (status)
{
UploadStatus.Text = "File Uploaded Successfully";Server.Transfer("Admin_PropertyView.aspx");
}
else
{UploadStatus.Text = "Uploaded Failed";
}
}
}
--------------------------------------------------
But when I click on the button, nothing happens.
Please could someone help me out here. I have tried this a few times and still haven't come right.
Also, if there is something else wrong with the code, please let me know.
Thanking you in advance.

Hi everyone,
I am currently reading ASP.NET unleashed and practising few examples. The following code converts a user's text into a symmetric encryption:
'nd: define keys
Const DESKey As String = "ABCDEFGH"
Const DESIV As String = "HGFEDCBA"
'nd: convert string to byte array
Function convert2ByteArray(ByVal strInput As String) As Byte()
Dim intCounter As Integer
Dim arrChar As Char()
arrChar = strInput.ToCharArray
Dim arrByte(arrChar.Length - 1) As Byte
For intCounter = 0 To arrByte.Length - 1
arrByte(intCounter) = Convert.ToByte(arrChar(intCounter))
Next
Return arrByte
End Function
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
Dim arrDESKey As Byte()
Dim arrDESIV As Byte()
Dim arrInput As Byte()
Dim objFileStream As FileStream
Dim objDES As DESCryptoServiceProvider
Dim objEncryptor As ICryptoTransform
Dim objCryptoStream As CryptoStream
'convert string to bytes
arrDESKey = convert2ByteArray(DESKey)
arrDESIV = convert2ByteArray(DESIV)
arrInput = convert2ByteArray(txtInput.Text)
objDES = New DESCryptoServiceProvider
'pass keys
objEncryptor = objDES.CreateEncryptor(arrDESKey, arrDESIV)
'create to file to save password
objFileStream = New FileStream(MapPath("secret.txt"), FileMode.Create, FileAccess.Write)
'pass in file and keys
objCryptoStream = New CryptoStream(objFileStream, objEncryptor, CryptoStreamMode.Write)
'pass in text
objCryptoStream.Write(arrInput, 0, arrInput.Length)
objCryptoStream.Close()
lblDone.Text = "Done!"
End Sub
It works fine. But, how to i save this encrypted password into a database field instead of a writing it to a file? Also, could some please tell me how to paste code into this forum? I tried <code></code> tags but it did not work.
Many thanks,
Kevin

We are creating an enterprise application for fuel, and I am fighting with my DBA about the proper way to store volume and currency in the database. We have 2 main arguments. The first argument is whether we should store costs in the database in $ and convert in the presentation layer, or to store the amount and currency in the database. We sell product from the US in dollar but depending on the customer we may invoice in Euro. Our second argument is the same, execept with volume and UOM. We often purchase product by BBL but sell/transfer by gallon, or Ton.
please tell us the best practice for our dilemma.
