I am working on a ASP.NET 2.0 project with an SQL 2005 database.
I created a documents table with various columns including:
DocumentId and DocumentUrl
My documents will always be PDF's of SWF's (Flash Paper Files)
I will need to display this files in my web pages.
My question is:
Should I save the DocumentUrl in the database or should I save the file itself in the database?
Hi, I want to upload a file (e.g. .xls, .pdf, .doc) and save into the Sql Server 2000 database through the web interface, and then to download this file. Any idea???
helo.. I want to save file it size about 200MB to the database and after that
I want to get it from the database, the colmun type that i want to
save the file to it is NVARCHAR(Max).
I am using MS sql server 2005.
I was using this code to do this with Image Or Ntext column type but
it dose not working with NVARCHAR(Max) column?
Function SaveFileToDB(ByVal FileName As String, ByVal TblName As String, ByVal FldName As String, ByVal ColumnIDName As String, ByVal RowID As String) As Boolean

Dim trParm As SqlClient.SqlParameter = addEmp.Parameters.Add("@Pointer", SqlDbType.Binary, 16)
trParm.Direction = ParameterDirection.Output
addEmp.ExecuteNonQuery()
'''''''''''''''''''''''''''''''''''''
Dim bufferLen As Integer = 1048576
Dim appendToPhoto As SqlClient.SqlCommand = New SqlClient.SqlCommand("UPDATETEXT " & TblName & "." & FldName & " @Pointer @Offset 0 @Bytes", MyConnection)
Dim ptrParm As SqlClient.SqlParameter = appendToPhoto.Parameters.Add("@Pointer", SqlDbType.Binary, 16)
ptrParm.Value = trParm.Value
Dim photoParm As SqlClient.SqlParameter = appendToPhoto.Parameters.Add("@Bytes", SqlDbType.Image, bufferLen)
Dim offsetParm As SqlClient.SqlParameter = appendToPhoto.Parameters.Add("@Offset", SqlDbType.Int)
offsetParm.Value = 0
Dim fs As IO.FileStream = New IO.FileStream(FileName, IO.FileMode.Open, IO.FileAccess.Read)
Dim br As IO.BinaryReader = New IO.BinaryReader(fs)
Dim buffer() As Byte = br.ReadBytes(bufferLen)
Dim offset_ctr As Long = 0
Do While buffer.Length > 0
photoParm.Value = buffer
appendToPhoto.ExecuteNonQuery()
offset_ctr += bufferLen
offsetParm.Value = offset_ctr
buffer = br.ReadBytes(bufferLen)

you see these are the requirements.. 1. there is a text file named "Loan" 2. i must create a program using ASP.net wherein the text file can be imported in the system. 3. after importing, i must save the whole text file in a database.
my questions are:
1. what code can i do to open up a text file? 2. how can i save the text file into a database? 3. is there any way that i could import the file and view its content in my application? 4. after viewing, how can i save the text file as a text file in a database?
Hi everyone, sorry if this message is not supposed to be posted here. I'm learning asp.net , and would like to know how I can insert data from a excel file into a database on my web account. Pretty much insert/update information in the database using excel file or a access file. Thanks a lot in advance
Hello:I didn't find any documentation that notes save point names are casesensitive, but I guess they are...Stored Proc to reproduce:/* START CODE SNIPPET */If Exists (Select * From sysobjects Where Type = 'P' and Name ='TestSaveTran')Drop Procedure dbo.TestSaveTranGoCreate Procedure dbo.TestSaveTranAsBeginDeclare@tranCount int--Transaction HandlingSelect @tranCount = @@TRANCOUNTIf (@tranCount=0)Begin Tran localtranElseSave Tran localtranBegin Try--Simulate Error While ProcessingRAISERROR('Something bad happened', 16, 1)/*If this proc started transaction then commit it,otherwise return and let caller handle transaction*/IF (@tranCount=0)Commit Tran localtranEnd TryBegin Catch--Rollback to save pointRollback Tran LOCALTRAN --<< NOTE case change--Log Error--Reraise ErrorEnd CatchEndGo--Execute Stored ProcExec dbo.TestSaveTran/*Should receive the following message:Cannot roll back LOCALTRAN. No transaction or savepoint of that namewas found.*//* END CODE SNIPPET */What is really strange, if there is a transaction open, then no erroris thrown. So if you execute as so:/* START CODE SNIPPET */Begin Tran--Execute Stored ProcExec dbo.TestSaveTran/* END CODE SNIPPET */There is no "Cannot roll back LOCALTRAN...." message.Questions:1-)Can someone confirm save point names are case sensitve and this isnot happening because of a server setting?2-)Is this a logic error that I am not seeing in the example codeabove?We have changed our code to store the save point name in a variable,which will hopefully mitigate this "problem".Thx.
I was using the msdn tutorial regarding sql database for vb2005 express. In that tutorial, I followed the steps as listed. But the problem is that the save button in my application during run time, it does not work. Furthermore, the code for for saving a record during run time does not work as well.
I have reinstall sql 2005 server and vb2005 express but of no use.
I use the DTS 2000 Migration Wizard to migrate one of the DTS 2000 packages to SSIS. The migration failed with the following error message:
LogID=17 #Time=6:31 PM #Level=DTSMW_LOGLEVEL_ERR #Source=Microsoft.SqlServer.Dts.MigrationWizard.Framework.Framework #Message=Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: Failed to save package file "C:Documents and SettingsfuMy DocumentsVisual Studio 2005ProjectsKORTONKORTONProcessCubesMF.dtsx" with error 0x80070002 "The system cannot find the file specified.". ---> System.Runtime.InteropServices.COMException (0xC001100E): Failed to save package file "C:Documents and SettingsfuMy DocumentsVisual Studio 2005ProjectsKORTONKORTONProcessCubesMF.dtsx" with error 0x80070002 "The system cannot find the file specified.".

Looking at the call stack, it looks like COM wrapper fails on SaveToXML. Can someone tell me how I should workaround this problem?
According to the help for SSIS, one method of deploying an SSIS package to a SQL Server, http://msdn2.microsoft.com/en-us/library/ms137565.aspx, is to use the File...Save a Copy of <package file> as... menu option.
I don't have that menu option at all. And yes, the package is in focus. My save menu options are simply; Save Selected, Save <package file> As... and Save All.
I am using Version 9.00.1399.00 of the SSIS Designer.
At one time I did have the Management Studio's CTP installed. However it was uninstalled before installing the tools from the Standard Edition. (it would seem like not completely however)
Your help would be greatly appreciated. Thanx much.
p.s. Almost forgot to mention... I am already aware of using the DTSInstall utility as a workaround. It should be noted, however, that despite enabling the "CreateDeploymentUtility" property, the DTSInstall.exe is not copied to the binDeployment directory.
Greetings, I have just arrived back into the country (NZ) and back into ASP.NET. I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page. Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer. Cheers ~ J
I used SQl Server replication to create a new database (as I did using Visual Studio 2003) but when I go the Pocket PC and click on the file I get a native error 25011 with a description
The file is not a valid database file An Internal error has occurred[,,,Databasename,,] Interface defining error: IID_IDBInitialize
When I check on my Pocket PC what programs are available I've got Query Analyser 3.0 and SQLCE Query. It appears that the .sdf file is associated with SQLCE Query because when I use that to try and connect to the same database I get the same error.
If I use Query Analyser 3.0 (after having copied the .sdf file) to the temp directory I'm able to open the database.
There is a similar post to this one but it doesn't help me.
Is it that SQLCE Query is wrongly associated with the .sdf file?
If so how do I change that?
Or is there some other problem preventing me clicking on the .sdf db to open it?

i'm trying to save data to an XML file from an OLE DB source using the "For XML" clause in the SQL command. Do I need to use a flat file connection manager or a raw file connection manager? And what destination do I use?
I haven't downloaded nor installed it but I have some general questions about it:
*Can I store a SQL Server-Express Database as a file, so that the Users can easily back it up or use my application as a portable one *Do the enduser have to install SQL Server Express or any addition when I'm programming for the .Net Framework 3.5?
I have the need to allow a user to upload a file via the web and then save it into a database. THen I also need to be able to retrieve the file for download.
Can someone give me guidance as to code or a sample on how to do this.
I have a asp.net application where i can choose to save any file(could be jpg or dat or txt or xml etc etc) into a table.So far,i've manage to save it into an SQL server table in a column(set to Image datatype).But when i get the data from the table,put it into a byte array and recreate it.I notice that the files can be recreated correctly if they are of type .txt files.But jpg files can't be recreated and trying to open the jpg files gives an error.I don't think it is the file saving that is the problem since any files can be save.Rather it is the file recreating that is the problem.Can anyone help?
Need advise on how to save objects like this in a sql2005 database, so they can be rendered to users thru a gridview control. Heard of saving a reference to location, but wondering if the entire object can be saved and served up with it's related data.
Is it possible to save a report as a CSV when the report is run without the user having to export the file? I need to save the report to a server location without the end user having to specify where.

I have a server with MSDE 2000 installed onto it. I also installed SQLEXPR_TOOLKIT.EXE . Now there is a DTS package present on that server saved in the DB. How can I alter that package? And if that's not possible: how can I save the package to a file so I can transfer that file to my development machine?
Hi guys, I want to update a PDF file and store it in the MSSQL database. (I know it is better if I save the file on server and just store the link to it, but I have to store the file on the database "Project Requirements") I would probably use FileUpload control to upload the file. but would I upload it to server temporarly and then save it or would I just upload it to DB. I appreciate your help and suggestions and any tips & tricks or issue that I have to consider. Regards,Mehdi
I want to write a small program (maybe just a stored procedure) that will save the results and column names of a simple query to CSV file. This will then be copied onto disk and distributed to user who'll use Excel or a similar package to open the CSV file.
Any suggestions as to the best way to achieve this? I was considering using a view and then BCP but I have problems then when trying to open the CSV file in excel (or other spreadsheet package). Doesn't like the datatypes and so on.
Is there a simple way to do this? And is it possible to save the results in such a way that Excel will choose the right datatypes for the columns. (not convert varchar's like '000122' to numbers.)
I would like to create a SQL job that runs a basic query monthly and saves the results as a .xls file and emails the results to a user. I've been unsuccessful with sp_send_dbmail in that the output file is always a single column. Any suggestions?
we always get all versions of the DTS File. Could you help us to Load or Save only the last version of the file? Is there any option of this procedure sp_OAMethod (or other) that solve the problem?
I am just beginning to work on an ETL project at a new client site using their computers. They are an IT department new to SQL Server. We have SQL Server 2005 up and running, no probkem. But I get that error when I try to add a new package to an SSIS project. The error number is 0x8002801D "Library Not Registered". I did see the post about the MSXML DLL files and when I try to load an existing package I get 3 errors regarding XML - stating that the MSXML binaries may not be installed or registered properly. I searched and found the MSXML3 & 6 DLLs but the MSXML4.DLL appears to be missing. If I repair the installation, will this fix it? BTW - the MSXML 6.0 Parser did show as being installed in Add/Remove Programs.
I'm developing a credit card application, and would like to store some sensitive data in a table temporarily, but be absolutely positive it either never goes into the log file in the first place, or is securely deleted from the log file when I delete the data. There's millions of other bits of data in the log, so truncating or otherwise disposing of the whole log is not an option.
In particular, I'm capturing the credit card mag stripe at the beginning of a transaction, and saving it while the work is done to complete the transaction. (ie, a pilot walks in, says "Top off the G4 with JetA, here's my card, have it ready when I get back.") We want to save the swipe info for maybe a couple of hours (it is encrypted during this time), use it for the authorization, then throw it away as per credit card industry rules.
Is there any way I can save the encrypted text string in a normal MSSQL field (Varchar(200)), have it stay around for a few hours as the user logs in and out of the database, then delete the record and be sure it's nowhere in the log?
TIA, George Lehmann Horizon Business Concepts, Inc. Broken Arrow, OK
Hm... I use SSIS packages to manipulate some data from one SQL server to another. I chosed "DontSaveSensitiveData" and I am using a XML configuration file.
The problem is I have to edit the file with notepad manually and add the password for my SQLconnections in it.
Is it possible to do this from the Business Intelligence Studio instead?
I tried to edit the connections and set and save password there but it won't save it to the XML configuration file.
Or perhaps it is intended to be edited in notepad and passwords set manually to it?
