I am currently importing (and exporting) binary flat files to and from Db fields using the TEXTPTR and UPDATETEXT (or READTEXT for export) functions. This allows me to fetch/send the data in manageable packet sizes without the need to load complete files into RAM first.
Given that some files can be up to 1Gb in size I am keen to find out a new way of doing this since the announcement that TEXTPTR, READTEXT and UPDATETEXT are going to be removed from T-SQL.
I had a quick foray into SSIS but couldn't find anything suitable which brings me back to T-SQL. If anyone knows a nice elegant way of doing this and is prepared to share, that would be grand.
I have a web application that I am rebuilding. I have many picture files that want to take off the file system and move into SQL as a blob. I will create an index of uids against the file names but need a good way to bulk add the files to the database... any hints on code or tools would be a great help. Thanks
Need help reading a binary file see below for details...

I'm trying to easily change a value in 80 ssis configuration files from "localhost" to "myservername". I downloaded WinGrep to do this, but it's balking on some of the files, saying that they are binary files.
Does anyone know how to make the *.dtsconfig files NOT binary in SSIS?
Any suggestions GREATLY appreciated.
I won't go into the reason I have my servername in 80 places...
hello! I am curious to know how I can find the length of a binary in Sql Server. The length doesn't work on binaries. ie select length(binary) from Binarytable
I want to have an SSIS package that processes a file in the normal insert, update style. But at the end I want to store the file as a binary field to another table for archive purposes. I am having trouble finding a good way to do this. Any samples, ideas, or articles would be appreciated.
hello dear friends I am trying to save a binary file to database with the following code: public static void memorystreamToDb() { MemoryStream mst = new MemoryStream(); UnicodeEncoding u = new UnicodeEncoding(); string Textn = "Test"; byte[] b = u.GetBytes(Textn); mst.Write(b ,0,Textn.Length ); BinaryReader reader = new BinaryReader(mst); byte[] file = reader.ReadBytes((int)mst.Length); using (SqlConnection connection = new SqlConnection("Some Connection String")) { SqlCommand command = new SqlCommand("INSERT INTO temp (examplefile) Values(@File)", connection); command.Parameters.Add("@File", SqlDbType.Binary, file.Length).Value = file; connection.Open(); command.ExecuteNonQuery(); } reader.Close(); mst.Close(); } or with the other method from a real file (not memory stream) public static void Addfile(string path) { CommonMethods_class k = new CommonMethods_class(); byte[] file = GetFile(path); using (SqlConnection connection = new SqlConnection(k.Get_connection_string())) { SqlCommand command = new SqlCommand("INSERT INTO temp (examplefile) Values(@File)", connection); command.Parameters.Add("@File", SqlDbType.Binary, file.Length).Value = file; connection.Open(); command.ExecuteNonQuery(); } } and after running each of them seams that the file have been saved; but I can not retrive the files. I have tried some solutions from msdn but inside the created file is empty. the point that i really look for it is to just working with memory not in the disk before saving. and then retriving each field that I want. looking forward your points thank you in advance
Hello all, I am exporting data from AS/400 into an xml file and then importing the data from the xml file into an SQL database. I am getting the error: "The statement has been terminated. String or binary data would be truncated" when there are characters like "," or "&" in the xml. How can i solve this problem? Almost all my records have characters like that because they include comments and i can't disallow the users from entering these characters (especially ","). Thanks,Mike.
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 am using FileUpload control in ASP.net 2.0 to upload files and store them into SQL server database as an image. I am fine with MS office files, image files and etc. We have Product Center (Proe) engineering software to configure parts and the files generated through this software have PLT extension when I store these files, the file type is Plian/text. I am using Fileupload.PostedFile.Content to get the file type. How can I store PLT, TIF files in SQL server? Please help.
I need to store several different types of documents (text, MS Word, PDF, etc.) in SQL Server 2005. What is the best way to store file attachments that have different MIME types?
Currently I'm using a table with a varbinary(max) column which works for binary files but not for text files. Do I need to have multiple columns in the table for different file types? Thanks in advance for your help.
CREATE TABLE dbo.[CM_Attachment] ( [Id] int IDENTITY (1, 1) NOT NULL , [Change_Request_Id] int NOT NULL , [Attachment] varbinary(max) not null, [Created_Date] datetime NOT NULL DEFAULT GetDate() , [Created_By] varchar(30) NOT NULL , [Modified_Date] datetime NOT NULL , [Modified_By] varchar(30) NOT NULL ) GO
INSERT INTO CM_Attachment(Change_Request_Id, Attachment, Created_By, Modified_Date, Modified_By) SELECT 6, BulkColumn , '', GetDate(), '' FROM Openrowset( Bulk 'C:TestingTest Doc #1.txt', SINGLE_CLOB) -- Does not work -- FROM Openrowset( Bulk 'C:TestingTest Doc #2.xls', Single_Blob) -- Works -- FROM Openrowset( Bulk 'C:TestingTest Doc #3.jpg', Single_Blob) -- Works as ChangeRequestAttachment
I have a design oriented question for a system I am developing. Because of various business concerns and issues we have been moving towards as desing that brings files into the SQL 2005 system as binary columns in a database. These files will then be processed at a later time using SSIS into relation model tables.
Normally I would just have the process be files are placed on a FTP location (or other drive path) and a location is stored in the database versus the storing of them as binary rows in the database. Then later the SSIS package runs using the path information for the conneciton manager.
Based on the proposed binary design I have two questions.
1. Can anyone speak to the advantages, disadvantages, issues they have had, etc to the binary storage method?
2. Can anyone make a suggestion on how they would handle the pulling of the file out of SQL when the file is ready to process? Do you stream it to a file and rebuild it on the physical disk, to then just import it with a connection manager for the flat file structure.... or can you stream it directly into a conneciton manager that reads it like a flat file and parses the file without ever going to disk? Any information on suggested implementations would be helpful.
when trying to ímport files to our database server from a client, I keep getting an error:
- Validating (Error) Messages Error 0xc00470fe: Data Flow Task: The product level is insufficient for component "Source_txt" (1). (SQL Server Import and Export Wizard)
Error 0xc00470fe: Data Flow Task: The product level is insufficient for component "Data Conversion 1" (175). (SQL Server Import and Export Wizard)
... doing the same import when logged on the server, hasn't been giving me any errors, how come. I can from my client without trouble import tables from other DB servers but when ever it is files it won't do it.
I tried as mentioned in other threads rerun setup to re-install SSIS, but as it was already installed it wouldn't re-install. My next move would be to make a clean install, but not sure it would help, as I think this is a buck.
Hey everyone I've got this question that has me stuck for the last few days but its an important part of my website.....What I am trying to do is basicly have a user be able to upload a file, have that uploaded file plus some other info automaticly display on other parts of my site, and have a different user eventually be able to download that file....I have thought about allowing the file upload as a BLOB but still cannot find a proper way to execute this using VB, plus I have heard that this way of doing it is not reccommeneded cause databases were not designed to store large files like this, lots of articles recommened having the file upload to a Folder on your server then get the binary data for the file that can be placed in a database to refrence that particular file.....Well this also proves to be a lot harder then said here is what I got so far (written in C#) protected void UploadBtn_Click(object sender, EventArgs e) { if (FileUpLoad1.HasFile) {
FileUpLoad1.SaveAs(@"C:Documents and SettingsAdamMy DocumentsVisual Studio 2005ProjectsWebsiteFiles" + FileUpLoad1.FileName); Label1.Text = "File Uploaded: " + FileUpLoad1.FileName; } else { Label1.Text = "No File Uploaded."; } } and here is the asp part of the code that goes with it<asp:FileUpLoad id="FileUpLoad1" runat="server" />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label> Now from what I know is I need to get the binary of the file which I have read you can do with the Page.Request.Files statement but again not sure how I would impliment this. Does anyone have any suggestions on which way I should take when dealing with this should I try and just use the BLOB method or use the binary refrence method? and if so how would I impliment this, heck even some good tutorials on the subject would be great... Thanks.....Adam
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)
I have a well-structured but also very large binary data-set that is generated by a C++ application every five minutes. The data needs to be accessed by SQL applications. Since data is generated every five minutes, performance is key, both for write and read. The data set is about 500MB.If data is written to the file system, the write performance doesn't involve SQL server. For reading it, I have a CLR to read the portions of the data that I need based on offset and length. That works and is very fast. The problem is that data is stored in the file system, so it is not self-contained within the database.
A second option that I haven't explored yet, is to write the data into a table as VARBINARY(MAX). I would read the data using SUBSTRING with appropriate offset and length. Performance of SQL write/read of binary data of this size, and whether there is a third option I haven't thought off. I'm using SQL Server 2014.
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?
Hi All, I am not sure whether this is the right place to post this question. But I am unable to figure out what is the best solution to retrieve and display an image in a html file(stored in varbinary(max) column). I have a list of images in the file and I am supposed to display them. Can anybody please let me know what is the best way to do this? Thanks a lot!!
I'm working on a report to show financial transactions from a table over a certain period. For most transactions there is a PDF document that is stored in a separate table in a binairy format. In my report I would like to include a link on every line with transaction information in the report that opens the PDF that is linked to that transaction. Just to be clear, I don't want to embed the PDF in the report but I want the users of the report to have the option to view the PDF that is related to that transaction in their standard pdf reader (adobe).
Code to do the following:
Once a user clicks on the link to view the PDF I need the code to get the binairy data of the PDF file from the table, convert it back to a PDF and open it in the default pdf reader (for example adobe reader). If it can't directly open the file then it's maybe possible to activate the 'open or download' pop up that you also get when you download something from a website.

Im looking to write a DTS script to import a CSV file into an existing table. I have made sure that all columns correspond. I ideally want to create a stored procedure and a variable to be entered as the file name.
