SQL Server :: Can't Read New Data From Database
Apr 1, 2011I am trying to read data from a SQL Server 2008 database. Initially, I imported a 2007 Access db into the server. I have no problem reading this data. However, if I add new data, either through code or through SQL commands on the Server, I get an error when I try to subsequently read it. I only get the error on new data, not the imported data. Error:
System.InvalidOperationException: Invalid attempt to read when no data is present.
In my page (ASP.NET/VB.NET) I have a dropdown box which is filled with Customer Names. No Problem there. However, when I choose the customer, the rest of the form is supposed to fill with data retreived from the database. If I choose original data, it works fine. However, as soon as I choose a newly added record. It throws the Exception. I have tried to find a solution online, but most answers point to missing read code. I think my code is right, as it reads some records correctly. Is there something that is wrong with my server, or the way I am writing the records?
There is a dropdown box name CNAME on my page...
OnSelectedIndexChanged runs the following code:
sub displaydata(s as Object,e As EventArgs)
locked.checked = "True"
edit.enabled = "False"
Dim CustomerName As String = CNAME.SelectedItem.Text
Dim dread as SqlDataReader
Dim cn As New SqlConnection()
Dim cd As New SqlCommand()
cn.ConnectionString = "Data Source=localhost;Initial Catalog=AnalyticalReports;Integrated Security=True;"
cd.Connection = cn
cd.CommandText = "select Customers.CID, Customers.CNAME, Customers.CADDRESS1, Customers.CCITY, Customers.CSTATE, Customers.CZIP, Customers.CCONTACT, ISNULL(Contacts.CONNAME,'none') AS CONNAME FROM Customers JOIN Contacts ON Customers.CCONTACT = Contacts.CONID
WHERE Customers.CNAME = '"+ CustomerName+"'"
cn.Open()
dread = cd.ExecuteReader()
dread.Read()
CID.Text = dread("CID")
CNAME2.Text = dread("CNAME")
CADDRESS1.Text = dread("CADDRESS1")
CCITY.Text = dread("CCITY")
CSTATE.Text = dread("CSTATE")
CZIP.Text = dread("CZIP")
CONNAME.Text = dread("CONNAME")
cn.Close()
dread.close()
End Sub

SQL Server :: Sum Value Of Previous Rows + Exisitng Row?
Mar 11, 2011I had a sql statement to prepare dataset for generate staff overtime work and time-off balance.

UNION ALL
SELECT Table2.staff_key,Table2.from_date,Table2.to_date,Table2.total_min ...... FROM Table2
the output of the sql statement should like this:
From To No. of hours
total_min Balance
01/01/2011 12:00 01/01/2011 17:00 7 hr 0 min 420
420

450

SQL Server :: Calculate A Compound Interest For Each Row Based On The Previous Row?
Sep 12, 2010I would like to calculate a compound interest for each row based on the previous row.
My table Table1 :
index sum quantity sum_after_interest
1 100 5 500(??)
2 500(??) 2 1000 (??)
3 1000(??) 3 3000 (??)
I marked in question marks the columns that I want to calculate, where I only have the sum for the first row and the quantity for all the rows.
Can this be done using views and inner joins or nested selects ?

View 8 RepliesDataSource Controls :: Failed To Update Database "C:MEMBERSHIP.MDF" Because The Database Is Read-only
Feb 8, 2010This is a very common error as evidenced but the very large number of problems and suggested solutions on the web. I finally got around it last week but can't remember what was the step that did it. At that time, I was building a web application rather than a web site. Is that the difference? As you can see, it is no longer in the APP_DATA folder and is named membership.mdf rather than aspnetdb.mdf. I ran aspnet_regsql.exe to create it and actually had it working and was updating it successfully. But for other reasons, I had to scrap the application and decided to re-create it from scratch as a web site rather than a web application. I had been using Visual Studio 2008 to build the web application but am now using Visual Web Developer 2008 Express Edition to build the web site. Unfortunately, the Visual Studio application will no longer open so I can't verify that the web application still works. Can anybody help? (Please!!!) BTW, ASPNET and NETWORK SERVICE both have full control over the membership.mdf.
