Hi
I've got a module that contains the following function.
Imports System.Data.SqlClient
Module SQL_Sprocs
Function ListUsers()
Dim conn As New SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("DBConn"))
Dim cmd As SqlCommand = New SqlCommand("list_users", conn)
cmd.CommandType = CommandType.StoredProcedure
conn.Open()
Dim dr As SqlDataReader
dr = cmd.ExecuteReader
ListUsers = dr
dr.Close()
conn.Close()
End Function
End Module
I then want to call this function from my webform. So I'm using the following
Dim dr As SqlClient.SqlDataReader
dr = Timetracker.SQLProcs.ListUsers()
Do While dr.Read
Label1.Text &= dr("first_name") & " " & dr("last_name") & ", "
Loop
dr.Close()
But it's not working. I want to have a module that contains all my sprocs and be able to call them from the individual webpages.
What am I doing wrong?

"I meant to delete just one assignment, doing which was giving me difficulty.
I deleted a whole category by accident which had most of my daily grades in it for a course with quite a few of them. I was negligent in backing them up, so I cannot restore them. I have an XLS file from the midterm, but am missing about 6 grades after that.
Is there any way to recover the grades I had in the deleted category. It has been a couple of days since I entered any new grades. HELP!"
My current backup strategy is to do a full backup 5 pm, differentials every 2 hours, logs every 30 min, all so they arenot simultaneous. Backing these all to same backup device via three different jobs.
Then the server is backed up to tape shortly after the 5 pm full backup.
Obviously, I can't restore from the backup for this situation because it would hurt other data.
But - is there a way I can take last night's backup from tape and restore it to a different database than our production database? (Such a database doesn't at this time exist. Would I detach, copy over the files, and then reattach on prod and attach on the devl side, and then restore from the backup device to the devl copy?)
I've never had to perform this kind of rescue and am wondering if my backup strategy is flawed since it isn't immediately evident how I can easily do this.
I needed a similar thing from our Oracle DBA yesterday, and he went to tape, copied out a table and put it on the Oracle database under a different owner, and I easily fixed the few records that I had botched.
That's exactly what I need to do now with MS SQL 2000.
As the faculty dude said, "HELP!"
And Thanks.
Hi,
I was hoping someone would be able to help me, I trying to go through several databases, 111 to be exact, and get the data out of a particular table which is present in all the databases on the same server.
I know how to get the names of the databases from the INFORMATION_SCHEMA, but how can use the name for it to cycle through all the databases and get data out of the one particular table.
Hi, I need some help. I have this query where i need to pull up students that have more than or equal to 3 absences in a row. Now I am getting all those students that are absent but not in a row. But i was wondering if there is a way to tell if a student was absent three days in a row . There is a date field that is being used to identify the day of the class and a status field that identifies if the student was absent or present. Please help someone.

Dear fellows,
Up to the moment I've got enough knowledge for read data stored into .LDF files by dbcc log and so on. It's very useful and interesting. Now, I wonder how to retrieve the same information but on MDF files.
At first, I want to make sure that is not possible by mean of traditional methods (dbcc or something like that) I suppose so but I'd like to hear opinions regarding that.
Thanks in advance for any idea, though or further information.
Ok, again, I'm reasonably new to this. I've been trying to display an image stored in SQL in a ASP.NET page. Pretty simple stuff I would have thought. I've read countless examples of how to do this online, and many of them use the same method of displaying the image, but none seem to work for me. The problem seems to lie in the following line of code:
Dim imageData As Byte() = CByte(command.ExecuteScalar())Which always returns the error: Value of type 'Byte' cannot be converted to '1-dimensional array of Byte'.Here's the rest of my code, hope someone can help. It's doing my head in!
Imports System.Data.SqlClient
Imports System.Data
Imports System.Drawing
Imports System.IOPartial Class _ProfileEditor
Inherits System.Web.UI.PageProtected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Get the UserID of the currently logged on user Dim NTUserID As String = HttpContext.Current.User.Identity.Name.ToString
Session("UserID") = NTUserID
Dim Photo As Image = NothingDim connection As New SqlConnection(ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString)
Dim command As SqlCommand = connection.CreateCommand()
command.CommandText = "SELECT Photograph, ImageType FROM Users WHERE UserID = @UserID"command.Parameters.AddWithValue("@UserID", NTUserID)
connection.Open()Dim imageData As Byte() = CByte(command.ExecuteScalar())Dim memStream As New MemoryStream(Buffer)
Photo = Image.FromStream(memStream)
End Sub
End Class
Dear Friends,
I have read many solution over the net, but since I am unable to utilize anyone according to my needs I am seeking help from you people.
I have a table imagedata in sql server 2005 having fields name and imageperson. Name is string and imageperson is Image field. I have successfully stored name of the person and his image in database.
I have populated the dataset from codebehind and bind it to the repeater.
By writing <%# DataBinder.Eval(Container.DataItem, "name")%>I am a able to retrieve the name of the person. But when I pass photodata as
<%#photogen((DataBinder.Eval(Container.DataItem, "imageperson")))%>
where photogen is function in code behind having structure
public void photogen(byte[] dataretrieved)
{
Response.BinaryWrite(datarerieved)
}
But it is giving error at <%#photogen((DataBinder.Eval(Container.DataItem, "imageperson")))%>
The best overloaded method match for '_Default.photogen(byte[])' has some invalid arguments
AND
Cannot convert object to byte[].
Can anyone please provide me working solution with code for aspx page and code behind.
Thanks and regards
VWD 2005 Express. I need to retrieve a value from a SQL database from the code behind a page and assign it to a variable. In Microsoft Access I can do this using the DLookup function. What I need to do is get the data that results from the following query into a variable:
SELECT [SystemUserId] FROM [SystemUser] WHERE ([Username] = @Username)
The name of the data source is SqlDataSource2
Also, in Access I can create a recordset from a query and then process through the recordset. Can that be done in VB code in VWD 2005 Express?

I've been traling the forum and the internet for a striaghtr forward solution on this.
I'm trying to do what loads of people have already achieved: retrive images from an SQL database.
I have successfully uploaded inages to an "iamges" table, storing the image as SQL type "image", also storing size, type, description, name etc.
I want to be able to read one or more of these images (and other data) back from the table.
I'm using C#, ASP NET 2.0, SQL,
Any examples I've found needed a lot of tweaking, and for some reason or other didn't work!
Please don;t just pose yet another URL to an example - I've probably tried it and failed already.
I don't mind if I display the images in a GridView or just within an aspx page.
Ideally I'd be able to dispaly a few images on a page.
I know how to read and display the rest of the data in the "images" table.
Can anyone help please?
Do you need more info?
Thanks in advance,

hi,
I have a SQL database that has Images stored. I am able to read the image from the database and display it. But i am not able to control the size and the position where it is displayed. I want to develop something like a photo album. the images should be displayed in a smaller size. but when the user clicks on the image, it should blow up to its original size.
I am struggling with this for some time. Any suggestions as how to develop it??.
Any help in this regard would be highly appreciated.
thanks,

Hi, I've been trying to write an sql statement that can output the 10 minimum entries from a database, but I can't figure out how to do it.
Any help?
this is a simple problem but it's just driving me mad as it's not reading from my dB. basically, I've have reviews stored in my dB and want to display them in a textbox by clicking on a button called btnReviews. I think the problem might be that there is too much text stored per row of the table (as it is a review), but I have the datatype set as text in sql. here's the simple un-errorred code I have behind the button. any ideas where I went wrong. i've a feeling it's something small but it's just taken too long to figure out.protected void btnReviews_Click(object sender, EventArgs e) { String strConn = ConfigurationManager.ConnectionStrings["conLocalDatabase"].ConnectionString; SqlConnection dbConnection = new SqlConnection(strConn); SqlCommand dbCommand = new SqlCommand("Select [ReviewC] From [Review])", dbConnection); dbCommand.Parameters.AddWithValue("Review", txtReviewView.Text); try { dbConnection.Open(); dbCommand.ExecuteNonQuery(); } catch (SqlException ex) { Console.WriteLine(ex.ToString()); } finally { if (dbConnection != null) { dbConnection.Close(); } } }

I have four tables that need to be loaded into an ASP.NET application. They need to be loaded together into one result set and sorted. Is it possible to load four tables together and sort them using an SQL statement?
To clarify, say I have the following data:
Table1: Anglesey, Cardiff, Ceredigion
Table2: London, Dorset, Lancashire
Table3: Antrim, Armagh
Table4: Glasgow, Berwick, Edinburgh
I'd want the data retrieved from all four tables and sorted so that the data retrieved would be:
Anglesey, Antrim, Armagh, Berwick, Cardiff, Ceredigion, Dorset, Edinburgh, Glasgow, Lancashire, London
I am aware of and am using the SELECT ... ORDER BY feature of MSSQL in my present ASP.NET application to retrieve from single database tables. I'm using merged datasets and a sort method to solve the above problem at the moment.
I'm preparing a report that will display provider number, provider name, and a single field that will show all the counties that specific provider serves. I realize from researching the coalesce posts that this can be done. However, when I try to retrieve data in the same select statement as my coalesce, I get the error: "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations."The listing of the counties must be specific to the provider, so my original code was:
DECLARE @Counties varchar(1000)
SET @Counties = ''
SELECT a.PROV_ID, a.PROV_NAME,
@Counties=coalesce(@Counties,'') + b.COUNTY + ','
from ECBH.dbo.tbl_PROVIDERS a inner join ECBH.dbo.tbl_Provider_Serv_Regions c
on a.PROV_ID = c.PROV_ID
inner join ECBH.dbo.tbl_Regions b
on b.REGION_ID = c.REGION_ID
where c.PROV_ID = a.PROV_ID
and a.MASTER = 1
I thought about creating a table to hold the coalesced values (need to coalesce two other fields as well), but wouldn't an insert to a table fail for the same reason?The counties table does not relate to the provider table, but does relate to a provider_county table (which in turn relates to the provider table).
Hello,
Thank you for reading this. I am faced with a problem where there is no storage of deleted or updated information in an OLTP DB. I am mostly concerned about retrieving the deleted data from a table when an update occurs so as to make the deleted data show as an error. Is there a way to retrieve these kind of data from a DB, if so how? Can these data be retrieved by dates? Also how much time do you have before the data can no longer be retrieved? Assuming that the data can be retrieved.
I know the good stuff about datawarehousing but unfortunately we have no DW. Any help will be greatly appreciated.

Hi to all,I made a database using SQL Server 2005 and now I want to interact with that database through VC++ 2005. Is that possible?? If so, how can I do it?
Thanks in advance!!!
Hello,
I am trying to retrieve only the first few characters (12 to be precise) from this string that is coming in from FoxPro to SQL Server 2005 and I am coding in C#. I have tried these methods (after reading it in a book, as I am new to this) but it still gives me an error saying that the field cannot exceed 12 characters.
autoClaimSalvage.Phone = "Select LEFT ('" + (string)(drInputDataSource["OWNPHN"]) + "',12) From '" + entityManager.TargetTable + "'";
autoClaimSalvage.Phone = "Select LTRIM(RTRIM(OWNPHN)) From '" + entityManager.TargetTable + "'";
autoClaimSalvage.Phone = "Select LTRIM(RTRIM('" + ((string)(drInputDataSource["OWNPHN"])) + "'))" + entityManager.TargetTable + "'";
Please let me know what i am doing wrong and if anyone has a sample code or if you can point me in the right direction, I will appreciate it.
Thanks for your help in advance.
I have been thinking of using SQL server 2005 as i would like the flexibility i get through UDT. Retrieving the UDT data in managed could is ok but i would like to retrieve it in non .NET languages too.
For example lets say i create a UDT "Point". I insert data in a table that has some columns of type point.
Now is there a way i can get the data of the type point in a point object in non .NET languages like perl, python...
Hi,
I am using Visual Studio 2008 with .NET 3.5 Visual Basic. I'm having a problem retrieving data from my SQL CE database.
I have a function that imports a file, parses it and writes the contents to a database. When I then query the database from my code, the data I have just written doesnt seem to be there. Even when i close and re-run the program. Only when I first view the table contents through Visual Studio then re-run the program does the data show up.
The things I know are. When I insert data there is no problem. I can view the data through visual studio server explorer. only when I view data through the server explorer can my code retrieve it.
Could this be something to do with caching? Any help would be appreciated. The (stripped down) code I use to insert data is below
kevin
Dim rowsAffected = 0
Dim connection As New SqlServerCe.SqlCeConnection(connectionstring)
Dim transaction As SqlCeTransaction
' command objects for inserting a ContactList and retrieving its last identity
Dim cmdInsertContactList As New SqlServerCe.SqlCeCommand("INSERT INTO ContactLists (Name, FolderID) VALUES (@Name,@FolderID)")
cmdInsertContactList.Parameters.Add("@Name", SqlDbType.NVarChar)
cmdInsertContactList.Parameters.Add("@FolderID", SqlDbType.NVarChar)
Try
connection.Open()
transaction = connection.BeginTransaction()
cmdInsertContactList.Connection = connection
cmdInsertContactList.Transaction = transaction
' insert a new list
cmdInsertContactList.Parameters("@Name").Value = list.Name
cmdInsertContactList.Parameters("@FolderID").Value = folder.ID
rowsAffected += CInt(cmdInsertContactList.ExecuteScalar())
transaction.Commit()
Finally
connection.Close()
End Try

I've played with various configurations of the MS SQL Server encryption functionality, and come across an embarrassingly easy question that I cannot seem to resolve. How do I retrieve the actual symmetric and asymmetric keys out of the database?
I'd like to explore the possibility of off-loading the encryption/decryption work from the database server to a load-balanced pool of servers. For this model to work the pool would need access to the keys. The symmetric keys currently are generated with the command...
create symmetric key EncryptionKey211
with algorithm = AES_256
ENCRYPTION BY certificate CreditCardCert
Am I missing something obvious here?
I have inherited a database and with it a set of triggers that are 'apparently' installed. However I have a number of different 'versions' for a specific update trigger and it is not clear from the files which is the latest, hence I am unsure of what 'version' of the trigger is installed in the database itself.
I am trying to retrieve the trigger code from the databse so that i can correctly determine which one of my trigger files is the latest version.
I don't want to end up in a situation where an earlier version of the update trigger is installed as this could wreck the underlying data.
I have tried using the syscomments.text column that relates to the trigger but it only gives me a concatenated version of the sql code and not enough to determine which file version was used for the trigger.
Is there a way of retreiving the entire SQL code that was entered rather than just the first few lines?
