I was assigned a project to read binary data file (2G) and select data from OrderID, OrderDate and Price three columns (there are about 50 columns) into SQL table.
Where to start? Do I need to convert entire binary data file into text file?
Hi all, I have one table with a column of type 'image'. There are manytypes of files saved in that column (i.e. .Doc,Xls,Pdf,jpg,gif etc.). What I want is, read that files from database and save it in temp folder on d drive of server. Can anyone help me in my problem? Thanx in advance
I have been trying to store binary file in a folder from the SQL Server.
Here is the code I am using to do this but, it is not working. It doesn't show any error only shows 1 row(s) affected. The folder remains empty after running this query.
I'm using a bit-wise comparison to effectively store multiple values in one column. However once the number of values increases it starts to become too big for a int data type.you also cannot perform a bitwise & on two binary datatypes. Is there a better way to store the binary data rather than int or binary?
Here is my task I am storing pdf's in sql server. I would like to retrieve the binary data from sql server and write the pdf content into an existing aspx page to the appropriate pageview section. What is the best way to handle this. The code works below but it loads a new browser with the content. I need it to appear in it's tabbed section in the original aspx file. Any assistance you can give me would be greatly appreciated. Thanks Jerry oSQLConn.Open()Dim myreader As SqlDataReader myreader = myCommand.ExecuteReader Response.Expires = 0 Response.Buffer = True Response.Clear() Do While (myreader.Read()) Response.ContentType = ("application/pdf")Response.BinaryWrite(myreader.Item("img_content")) Loop
There are two datatypes for storing binary data type in the SQL Server:1. binary - for fixed length binary data2. varbinary - for variable length dataMy question is: how is data inserted into them? Do they have anydelimiters that go into the insert statement like strings and datetimeshave? What format (hex/decimal?) do they accept data in? Can you pleasegive me an insert statement example?
hello. i have a _CommandPtr that has the type CommandTypeEnum::adCmdTex, and the CommandText a query("Select * from Table_1") and this select returns one row that has a binary data in it.
Code Block
_CommandPtr pCommand; //Create the C++ ADO Command Object
pCommand.CreateInstance(__uuidof(Command));
pCommand->ActiveConnection = this->pConnection;
//Make the ADO C++ command object to accept stored procedure
Code Block long GetArraySize(const VARIANT& var, long * nElems) {
if ( !(var.vt & VT_ARRAY) ) return -1;
long size = 0; long dims = SafeArrayGetDim(var.parray); long elemSize = SafeArrayGetElemsize(var.parray); long elems = 1; for ( long i=1; i <= dims; i++ ) {
long lbound, ubound; SafeArrayGetLBound(var.parray, i, &lbound); SafeArrayGetUBound(var.parray, i, &ubound); elems *= (ubound - lbound + 1); } if ( nElems ) *nElems = elems; size = elems*elemSize; return size; }
I enter in VARIANT var = pRecordset..... and if gives me a value... but when I put it in Memory explorer in VS, i only see this data " fe ee fe ee fe ee fe ee fe ee fe ee fe ee ...fe ee" and of course it brakes at SafeArrayGetLBound(var.parray, i, &lbound);
Can someone tell me where I am doing a very bad thing?
P.S. I was able to read the binary data from the server using C#.NET 2.0.
Hey all, WE have a document management system where by Adminstrators can upload documents, once the document is uploaded the binary data is stored on in a folder on the web server. We used to stored the documents in the actaul db table, but we found that there were to many documents and it was using alot of space on db server. So my boss has decided we are now going to upload the binary data onto the web server. Currently we are donig this with new documents which have been added or documents which are gettinguploaded when reloading, but there are many documents in the db table which have not been updated and are still embedded in the db table. So i need to figure out how to go about copying the data storewd in the db table and storing it in web servers folder location. I've tried various things for a enitre day but im going round in circiles. MemoryStream mStream = new MemoryStream((Byte[])dtrResults["file"]); BinaryReader bReader = new BinaryReader(mStream); int intFileSize = (int)mStream.Length; Byte[] byteFile = (Byte[])dtrResults["file"]; i can get to this state but then how do i create a folder on the BinaryREader to then store the binary data of the file to the location. BinaryReader bReader2 = new BinaryReader(File.Open(strDocFolder + strSavedFileName, FileMode.Create)); int count2 = bReader2.Read(byteFile, 0, intFileSize); bReader2.Close();i've also tried this but when the file gets created in the folder there is no content. i do know that the file does contain content as ive tried this and downlaoding the file from that page acctually works string strContentTpe = WValue.WStr(dtrResults["contenttype"]); int intFileSize = VValue.VInt(dtrResults["filesize"]); / Byte[] byteFile = ((Byte[])dtrResults["file"]); //Downloads the data correctly Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("Content-Disposition", "attachment; filename="" + WValue.WStr(dtrResults["docfilename"]) + """); Response.AddHeader("Content-Length", WValue.WStr(intFileSize)); Response.ContentType = strContentTpe; Response.BinaryWrite(byteFile); I hope ive made some snese andthat someone can hlep me. Have a nice dayZal
(Appologies if this group isn't the best place for this post)Is it possible to use DAO 3.6 to access binary data (varbinary(max)) inSql Server 2005? I have images and sound in a Sql 2005 DB that I needto retrieve (and write) with DAO (ADO and ADO.Net are not options asthis is legacy code that can't be changed).Thx,Marcus
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.

Hi I've followed a tutorial on how to write and read varbinary(max) data to and from a database. But when i try to read the data i get the error that the data would be truncated, but only when the varbinary(max) is greater then 8kB. I've used a system stored procedure (sp_tableoption) to set the table that holds the data to store data outside rows. To select the data i'm using a stored procedure: SELECT imageData , MIMEType FROM Pictures WHERE (imageTitle = @imageTitle) And then using an .aspx page to Response.Write the data:Using conn As New sql.SqlConnection conn.ConnectionString = ConfigurationManager.ConnectionStrings("myConnectionString").ToString Dim getLogoCommand As New sql.SqlCommand getLogoCommand.CommandType = Data.CommandType.StoredProcedure getLogoCommand.CommandText = "GetPicture" getLogoCommand.Connection = conn Dim imageTitleParameter As New sql.SqlParameter("@imageTitle", Data.SqlDbType.NVarChar, 200) imageTitleParameter.Value = Request("imageTitle") imageTitleParameter.Direction = Data.ParameterDirection.Input getLogoCommand.Parameters.Add(imageTitleParameter) conn.Open() Using logoReader As sql.SqlDataReader = getLogoCommand.ExecuteReader logoReader.Read() If logoReader.HasRows = True Then Response.Clear() Response.ContentType = logoReader("MIMEtype").ToString() Response.BinaryWrite(logoReader("imageData")) End If End Using conn.Close() End Using Can anyone please help me with this?!

exporting an SSIS from a 2008 R2 SQL Server and re-import it into a SQL 2012.
I have inherited an SQL 2008 R2 Server running two SSIS packages. I have both as .dtsx files and & a manifest to install.The task at hand is now to migrate those to a new SQL 2012 server.[There is also an IIS running on that machine and project-specific .dll and stuff within the IIS document root. I do not know if these .dlls relate to the IIS web page or to the SQL .dtsx) But the migrated web site runs fine].
Installation of the packages into the MSDB works out flawlessly and one of the scripts runs fine, but the other fails to run with the error:
"Error: the binary code for the script is not found. Please open the script in the designer by clicking Edit Script button and make sure it builds successfully."
Google tell me something about a "Pre-compile option"-setting on server as explained here. I can not find this option setting anywhere in SSMS. Also as the migration is from 2008 R2 -> 2012 this should not be relevant as in both versions pre-compilation should be automatic, right?
- I installed visual studio 2013 community
- I installed SSDTBI
- Start the "Integration Services Import Project Wizard"
to import the SSIS directly from the "Integration Services Catalog"
However, things don't quite work very well - Trying to import (from the locally installed SQL instance) it will not display the tree of SSIS stuff, but only the root directory.
So importing directly from the running system won't work. Let's see if we can get somewhere with the .dtsx As I _do_ actually have the .dtsx files here, why not open them up directly in Visual studio and try to get compiled whatever needs to be compiled.I create a new "integration Services" Project and open up the .dtsx into this project. ==> LOTS of errors of all kind.
(The job of this script is to fetch messages from an Exchange.)But opening up this specific bit of code doesn't work a bit - there is no binary code in it and how to reate it or where to get it from...
After adding Service Reference to WebService, the Script Component has Binary Code not found, red circle not showing these are the steps I followed:
1) Add Script Component as Source 2) Add 3 x Output Columns Col1,2 and 3 3) Add HTTP Connection URL>..Binary Code not found, red circle showing 4) Add test code to Sub CreateNewOutputRows Dim i As Integer = 6 Binary Code not found, red circle not showing 5) Add Service Reference URL...Binary Code not found, red circle showing again
Should just adding Service Reference cause Binary Code not found, red circle to appear. I have to set precompilescripttobinary option , however cannot see this option in 2012
When I enter over 4000 chars in any ntext field in my SQL Server 2005 database (directly in the database and through the application) I get an error saying that the data could not be updated because string or binary data would be truncated.Has anyone ever seen this? I cannot figure out what is causing it, ntext should be able to hold a lot more data that this...
When using AquaData or JDBC (inet tds driver), when doing an insert using SqlServer 2005, I get error "String or binary data would be truncated" when the data is actually OK. There are no triggers, etc. that would confuse the situation. It works fine in SqlServer 2000.
Create and populate table: create table maxtable ( tablename varchar (18) not null, [...] )
Try to insert into test3: insert into test3 (name, tbname) select i.name, o.name from dbo.sysindexes i, sysobjects o, maxtable m where i.indid > 0 and i.indid < 255 and i.id = o.id and i.indid = 1 and o.name = lower(m.tablename)
And I get the error "String or binary data would be truncated." The values being selected for i.name and o.name have maximum length of 18. There are other rows in sysindexes and sysobjects with longer values, but they are not being selected.
The error does not occur with SQL Server Management Studio, and does not occur using SqlServer 2000.
is there a way to change SSMS 2012 default query save location?
Scenario:
1. Open SSMS 2. Create new query 3. Click Save
I see "DocumentsSQL Server Management Studio" folder, but I want to change it to be "d:". How do I do this? I tried:
1. [URL]- in folder "DocumentsSQL Server Management StudioSettingsSQL Server Management Studio" there is a file NewSettings.vssettings, setting it to "d:" or "d:" didn't work.
2. Changing HKEY_CURRENT_USERSoftwareMicrosoftMicrosoft SQL Server100ToolsShell VisualStudioProjectsLocation didn't work too. There is no "Shell" under "110Tools"
Did I do something wrong, or is there another way?
I have a table with 10 rows with a varbinary column
I wish to concatenate all the binary column into a single binary column and then write that to another table within the database. This application splits a binary file (Word or PDF document) into multiple segments (this is Column2 as below)
Get a filestream download link with only access to read and with folder navigation
I need a link with the path to get the file stream blob, that path could be used to download a document using any windows app like windows explorer, etc. the requirement is that path does not allow customer to navigate in filesstream share folders or see other files and only can read the file of the path,
Checking :
[file_stream].GetFileNamespacePath(2)
Allow you navigate in folders.
NON_TRANSACTED_ACCESS read_only, resolve the requirement to disable the save in file table, but allow you navigate and see other files.

I am working on a program in VB 2005 in which i want to store and retrieve GPS coordinates. I am not sure which data type is the best to use to enter Latitude & Longitude numbers and maintain their proper integrity.
Like LAT ( N38 28.025' ) and LONG (W105 52.098' )
The numbers will be entered by the user and that format can be maintained, but how to re-enter & or insert them into the database using the same format is my real question.
I hope I have explained this right. The numbers in BOLD are what I need to maintain.
