How To Load/Unload Non-Graphical Files Into/From IMAGE Field?
Dec 13, 2007
I want to be able to load and unload, byte-for-byte, a file to and from a field of data type IMAGE in a SQL Server CE database. The files are larger than 8000 bytes so IMAGE appears to be the way to go data type wise.
I'm using VB 2008 but pseudocode for any VS language would be awesome.
I was able to do this without much effort using ADODB and its stream object, fetching a recordset object and updating the appropriate data field one "chunk" of bytes at a time. I cannot for the life of me find a way of doing this using, for example, a SqlCeResultSet.
I've tried using ADODB to connect to a SqlCe SDF database file, using a connection string that I found online, and am able to write action and select queries successfully against the database... but when I try and return a recordset that is updatable, it returns an error. So no help there.
I've searched other threads in the forums, and online in general, and I've found information on loading/unloading graphic files using a memoryStream and the toArray method thereof, but this will not work as many of the files I want to load and unload as BLOBs are not graphical in nature. FileStreams do not implement the toArray method, so I can't just stream an arbitrary file's worth of bytes that way. I also do not want to change the original file in any fashion--e.g., a hash of the source file should be identical to the file after it has been loaded into the data field and then unloaded into a new file.
I have been fighting with this all day. If you can point me in the right direction I'd appreiciate it. I need to load about 500 jpg files into a table. The table has 3 columns an "ID", "Filename" which has the filename of the jpg in it already, but not the unc path, and a ("Photo" Image Datatype)column which is not populated yet. I need to store the Image file in the photo field so that I can run reports in reporting services and so on and so forth. I am not sure how to complete this task.
Hi, I have a concern about adding a new field to a table with image field - which is huge. Will there be a problem with some databases, where they have a hard time locating data correctly after such a large field? Previously this happened to me, and what was advised to put all the big fields at the end of the table. Thanks.
I need to write codes to access many image files and wave files and display them on the webpage. Both of these files are stored on the server (as many experts in this forum adviced) and their locations are in the SQL server database. About the wav files, I think I will have to convert them to MP3 first for fast delivery on internet. Since I am a newbie, any help would be appreciated. Thanks,
I have a table structure like this EmpID LastName FirstName Emp_Picture 100| x |T |<BINARY> 200| W |W |<BINARY> .. .. ETC This table has 935 rows in it with Emp_Picture Blank.
How to insert the jpeg files into the Emp_Picture Column?? Do we have run the update statement for each and every employee or is there a way to get around this problem..
What are the negatives, challenges and issues going to be if we choose to store 300-1000 GB worth of image, xml and PDF files (avg size 1 mb) in SQL server 2005 db.
I have a directory of files that I would like to upload with some datato a table so that I can store the files in the db. I'm not trying toparse files into rows, I want to stick the actual file in the column.Is there some kind of insert script, or bulk copy that I can use?I have about 150 docs and I would rather not go through the whole app,pick the file, upload it. etc.thx,M@
Hello,What's the best way to store files of an arbitrary size in a SQLServer / MSDE database? Some files will be text, but most should bebinary (images, audio, and video). I'd like to be able to store allthe files directly in the database so that backing everything up is asingle operation (I can do this, right?). Data retrieval speed is notoverly critical, as the code in question will be running on the samemachine as the database and will only have a single instance of theclient application. Any advice and/or hyperlinks to whitepapers on thesubject would be appreciated.Thanks,Will GantJoin Bytes!
the connection string in my application daynamic ..changed by changing the development environmet ..how can i load a data from file to sql server destination without hard coded the connection
I need to store a few thousand images in a sql server database. I've managed to write the asp code to retrieve images that are already in the pubs database, but haven't been able to find a satisfactory way of inserting new pictures in the first place.
At the moment we're using Notes and its great 'cos you just cut and paste them in. But now we need to take them all out and put them into sql server it's proving to be a nightmare. Any clues anyone??
I did some quick Googling and didn't find the article of my dreams here. Any experience with storing files in the db in 2005? Any opinions?
Here's the deal. We have our new 'Enterprise' software being designed and written in St. Petersburg (not FL) and I'm reviewing the design for dealing with letters and forms that are generated as hard copy from our business (by the thousands per month) and sent to clients for review, signature etc. Then they are returned by fax or snail mail.
The current design has all of these being stored in image data type columns in the database--storing saved files of the actual outgoing stuff and saved files of the stuff that comes in (scanned copies or the files from our fax server).
This screams 'BAD IDEA' based on our experience doing this in SQL Server 2000. We get things like 23 page faxes from Dr's offices, large packets of FMLA forms returned, etc. In 2000 they tended to get rather large when stored in the DB and caused us all kinds of headaches when Microsoft changed how it recognized and displayed certain types of files, e.g. tiffs.
Further, the outgoing stuff is largely boilerplate with added fields from the db--name, address, a few dates. My proposed design for outbound notifications and forms was to keep only references to the template used, the date created, and an id to link it to the personal info of the schmoe to whom it was sent--essentially, store which document template and then just enough data to map to the variable content that is pulled from the db. Then you can recreate the file that was printed and mailed at any time in the future, but you don't actually save the .doc (or Word .xml) anywhere, not in the file system, not in the db.
The current developers feel this is way too much work to design--and it is certainly more effort than just generating .docs/.xml files via a merge with Word and then stuffing those into the database. They also argue that having them in the db makes them 'more secure' and more 'accessible' to users around the globe.
Does anyone know if the image storage is any better in 2005 than 2000? The .docs & .tifs we used to store just about tripled in size when we put them in the db in 2000. Plus there were the defrag issues and generally it was an unsatisfying experience.
Does anyone know what the advantages/disadvantages of generating Word .xml files might be? Can they be stored as xml data type in SQL Server? Perhaps this is a better option?
If anyone has the time to digest this, please send opinions.
I just want to store pic.bmp file in server using image datatype but don't getting how to do that .. i want to know about both the actions storing and retrieving from the image data type.. like
create table amit ( im image, );
insert into values ()... select * form Amit will it work...
As part of a web site I allow users to store documents in SQL Server 2000 using an Image column on a table. After the file is saved the user can open the document through the browser. This works great for most file extensions such as ".XLS" or ".DOC" but fails when attempting to open ".MSG" files (saved outlook messages). XLS documents will open in Excel and DOC documents open in Word, but MSG documents open in Notepad and display what appears to be binary data. I'm trying to figure out if this is a SQL Server issue or some sort of ASP/ASP.NET webserver issue.
If I attempt to open an MSG file stored directly on the web server, the file opens correctly using the "Microsoft Outlook View Control", but when attempting to open the same file saved in SQL Server, it attempts to open in notepad.
Hi, I have problem I'm hoping someone can give me some pointers with.
I need to load data from several text files into one table. The format of the files are simple - each line is comma separated, with double quotes around each element e.g.
However, the files themselves will have different numbers of columns e.g file 1 may have 8 columns, file 2 may have 16 columns.
I'm going to load the data into a table that has at least as many columns as the longest file. The table columns are all varchar, and are named simply as [Col001] [Col002] [Col003] etc...
The first two columns of this table must be left empty during the load (I use these later on), so the data entry will start at [Col003].
My question is what is the best way to do this? I thought perhaps using a BULK INSERT in a stored procedure might do the trick, but I haven't used it before and haven't got very far. I gather another approach might be to use bcp utility. Someone has also suggested a DTS package, but the filenames will be suffixed with current date/time stamp, so i don't think that will work.
My preferred appraoch would be the BULK INSERT..but i'm open to any pointers.
I have around 140 text files in a folder where all the file entries are delimited by tabs. Currently i am copying the data and then pasting it in to the tables and it is perfectly working fine. I have already created tables for those 140 files. But now i want to load those files in to the table at a single shot. How can i do it? I am using SQLServer 2005.
and get the values of all the <XMLFileName> attribute and load them into some variables,say here the filename is "17470_652.xml", I have to look for this file in a specified location, open the XML file and load the contents to a table ? It can be presumed that all the XML files will be stored in a same location
I am new to SSIS and am looking to load XML files (with a DTD definition) into tables via a SSIS package. I have created a XML task and am able to load the XML and output it to file. I have also stripped out the DTD definition and am able through a dataflow using XML source an OLE db Destination load and map the XML to table sin my DB. But have no idea how to get the data in when it has a DTD definition included. I either want to put each file into a row in a table then query it. Or from the SSIS package input the relevant info into a set of staging tables or the real tables.
HI All, I have Uzip Files to be loaded From ftp.companyname.com, the zip files get updated everyday thus i have to load the newly added files, the Zip file has got 13 text Files within it, the issue is: 1. how do i load it for the new zip file only, the zip files are shown below, i am trying using FTP Task, but need more info. 2. How do i UnZip it and and take the text files and then load them to sql server 2005, each text file has to be loaded to sql server tables. 3. How do i automate it, i mean every time i run the package (on Job based) it has to look the new file only, see the zip file below to understand what i am saying about.
As you can see the Zip file names are the blues color, they are added at different time, thus what i need is only the current Zip file (i mean i have to Load only the newly added Zip file (recent one)). Thus the SSIS Task has to go to this FTP server and look the newly added zip file. After that i have Unzip it b/se i have 13 text files there, and then Load them to Sql Server 2005.
Please get help on this, the deadline is near by time, if possible try as soon as possible, I would like to say Thank you for every help you do and try. Thanks,

DTS is not properly exporting a database between the servers when a table is containing a image fieldReason it gives as ::Error::Transfer Status: Transferring Data: (Table '[dbo].[Here comes the table name used ]') Data truncation occurred in table [dbo].[Here comes the table name used ], column 1. any workaround or solutions would be more appericated
Hi,Tasks in a MS Project SQL Server database have an image field calledTASK_RTF_NOTES. It contains text in RTF format. We would like to convertthis within a standard SQL statement into plain text.I suspect this is not possible without some sort of bolt-on, or at the veryleast using T-SQL in some way.Any ideas?Thanks,Gareth
