I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.
1. How can I upload new pictures into the database through the browser. 2. Can you describe how the new picture of the product would be uploaded into the database. 3. How do you handle different formats that pictures come in gif, tif, jpeg, etc.
4. How can you say that SQL server does support images well, because on microsoft site they loaded up the satellite data of the earth into sqlserver which is only picture data
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 got this issue when I am trying to store an Image on a database through a stored procedure. I give you the code in C# and the stored procedure
Code Snippet
//I have got these two variables with the ID(foreign key) and the array of bytes of the Image (the values are OK) int ID_Inmueble byte[] imagen -- dimension 26246
SqlConnection conn = new SqlConnection(...) //The conexion works fine (I tested it).
I am using an image datatype to store multiple filetypes includeing plaintext data. it works except for pdf Data. When I retrieve the the filecouldn't be opened in acrobat reader and the file was 3KB bigger than theoriginal.Any suggestions would be helpful.
I have a very large array of floating point numbers which I am tryingtostore in an image type field. I am using the dataset class todirectly enter the data but am having trouble trying to get this typeinto the image field. I guess the question is how do I get a largefloating point array into an image (byte)field of a database using thedataset class for new row entry.Thanks
I'm storing thumbnails in SQL CE and accessing them from my WPF application. The save seems to take place ok and there's binary data in the image field however when it comes back out it appears to be corrupted somehow. Can someone have a look at the code below and verify I'm doing the conversion correctly before storing in my image field? Thanks!
Just starting to investigate this. I need to store digital pictures in my database for use in claims and disputes. I have played a bit with the image datatype but notice that one picture takes up 1Mb as a TIFF and 3Mb as a JPEG. Does anybody work with this stuff and if you do what is the best picture format to use in regards to keeping clarity but minimizing size used in the db. Is there any load conversion routines that would shrink the size of the file.
Any suggestions or comments on this topic are appreciated.

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 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.
Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?
Hi, I have a website and i am uploading the gif image to the database. i have used varchar(500) as the datatype and i am saving the file in the webserver so the path to it c:intepub....a.gif
my upload table has the folliwing feilds UploadId Int Identity, Description, FileName, DiskPath varchar(500), weblocation varchar(500). I have a main sproc for the report where i am doing a inner join with other table to get the path of the gif..
So my question is how can i get a picture to show up on the report. . What kinda datatype the gif file should be stored in the database? If it is stored as a varchar how can i access it and what is best way to reference that particular.
Hi, I have to create a datebase for an assignment and I am using MSSQL and need a little bit of help for something that I don't think can actually be done. Basically I have an artist table. Now each artist may well have a website of their own where their biography can be found. In my artist table I have an artist_bio field where I want the URL of the artists bio to be placed and only the URL. So for example I would want www.iamanartist.com/mybio to be put into that field. So I was wondering if there was a constraint that could do this? I don't think there is because URLS can be so complicated but if someone could tell me whether it is or isn't possible I would be really grateful. I am also wanting to do something similar with the location of a hardcopy of their work. So I have a digital_images table with a location field where the loaction of their work will be on a harddrive. Is this possible or not as well? Cheers for any help you can give, Liam
I have column with location for all reports, dashboards, images, pages in URL format from Sharepoint audit database. Like
sites/fm/finance/PowerPivot Gallery/FinancialStatement.rdlx sites/ea/Mn_medical/Pages/Medical_DP/3 Site Compare.aspx
There are millions of rows like the above URLs. I need to separate all the strings from that ULR separated by "/" and make column for each so that I can create a hierarchy in tabular model. How do I write a sql for that. I could get first one and last ones with these kinds of substring:
SUBSTRING( b.DocLocation , LEN(b.DocLocation) - Â CHARINDEX('/',REVERSE(b.DocLocation)) + 2 Â , LEN(b.DocLocation) Â )
This gives me last piece of ULR. How I do I get all the middle pieces of URL?
I am an absolute beginner with SQL Server 2005 Express, and I want to make a new table in my database that stores web URLs and their Username and Password info. When I try to add a URL to the URL column, it says
Error Source: .Net SqlClient Data Provider
Error Message: String or binary data would be truncated.
The statement has been terminated.
I assume this means that the URL is too long to fit in the data type I specified, but I've tried almost every single data type there is, and I keep getting the same error. I was wondering if anyone knew what was wrong.
I have a system that basically stores a database within a database (I'msure lots have you have done this before in some form or another).At the end of the day, I'm storing the actual data generically in acolumn of type nvarchar(4000), but I want to add support for unlimitedtext. I want to do this in a smart fashion. Right now I am leaningtowards putting 2 nullable Value fields:ValueLong ntext nullableValueShort nvarchar(4000) nullableand dynamically storing the info in one or the other depending on thesize. ASP.NET does this exact very thing in it's Session State model;look at the ASPStateTempSessions table. This table has both aSessionItemShort of type varbinary (7000) and a SessionItemLong of typeImage.My question is, is it better to user varbinary (7000) and Image? I'mthinking maybe I should go down this path, simply because ASP.NET does,but I don't really know why. Does anyone know what would be the benifitof using varbinary and Image datatypes? If it's just to allow saving ofbinary data, then I don't really need that right now (and I don't thinkASP.NET does either). Are there any other reasons?thanks,dave
I want to be able to open URLs in a new window in my SSRS report, and the URLs keep changing in every record. The problem is these links are not the only things present in the record, and there is other data present. I keep seeing examples where they are considering only a link to be present in the record with no other data.
Also the data in the record includes HTML tags and I checked the option that says "HTML - Interpret HTML tags as styles" on the placeholder properties window.
Example of data in the record: Hello! Welcome to google, the most used search engine. Click on www.google.com to go the website
So when I click on the www.google.com URL, it should open in a new window.Â
best way to store questionnaire data in a database.Since different questionnairs have different questions and formats i.e dropdown, radio, checkboxes etc building such a database model becomes highly complex.
I've read that if data schema is complex and higly variable it may be better to use an xml document and store that in a databse. However I dont quite understand how you store xml to a database. Do you simply store the entire structure in something like a nvarchar column or is there some other way to store xml to a database.
If you store the entire structure to the databse then how do you query the content to generate reports.
I have a bit of a dilema, that maybe someone can give a reccomendation on. I have a vb app that will calculate a duration that a process runs in hours:minutes:seconds. My question is should I store this in the database as a date/time field or calculate total seconds and store it as an integer field? I will be using this field for basic summing calculations in the future. Thanks for any help.
