Images, PDFs, word documents, etc..., will it affect the performance of my sql if I stored them in it as blob objects? Or it's better to use the filesystem instead and just store file paths in my sql?
thanks in advance
Hi,
I need some tips regarding some performance issues and it would have been great if someone could provide me with the same. I'm into a project where we need to handle a lot of images dynamically. Images are delivered dynamically as per the users query. You can think of it something like an image search. The technologies used for this project are ASP.Net 2.0, C# and SQL Server 2000. I would like to know if the images should be stored in the database or as files itself. I did a couple of R&D on this and 90% of the places I found that it€™s better to store the images as files. As a final answer to this I thought I'll post this query in this forum. Irrespective of whether the images are stored in the database or as files, the following are some of the key features that I'm looking into (priority wise):
1. Performance - I would like to obtain the maximum performance. Images need to be delivered without
much delay.
2. Security of the data and images.
3. Easy backing up and restoration of the data and images.
It would have been great if someone could provide me with the right solution with supportive answers, so that I would be able to design the project accordingly.
Thanks & Regards,
Frens

please any help and advise would be much appreciated as i am stuck,

Can you store images in a database or in a table, or do you have to only store the image path/name in the database while the image is in another folder? IF anyone knows, please share with me. Thanks.
View 2 Replies View RelatedI have recently designed and built my first database using SQL server 2005 express. I have included an image (BLOB) column in one of the database tables. This is a bad idea according to some experts, and some say it is OK!
I am currently carrying out a trial with just 3 pictures via Visual Basic 2005 express forms, and there is no problem so far as the images are displayed for each record. But I anticipate between 300 - 1000 images for the table, and this could pose real problems for SQL server 2005 express and Visual Basic 2005 express, I guess.
I have just been reading that the cost of storing large images in the database is too high! I have also read it's better to store images (BLOB) into the file system because it is cheaper to store them no matter how many there are.
But the question is how I can reference an image in this path: C:PictureProductGrocery 0052745.jpg in the database table, so that when I select a record Visual Basic 2005 forms the image is displayed accordingly, similar as when stored directly in the database table? Your help very much appreciated.
hi can anyone tell how to use the image field and add an image in a database. i'm using visual studio web developer express edition 2008 and i want people who visit my website to be able to see the table and the images associated with some of the rows in the table

I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field.
I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?

We're considering purchasing an application,which stores some data in the filesystem, andsome data (meta data and links to files) inMS-SQL.We need to be able to create a backup whereinthe database and files are "in synch" (in other words,in a consistent state). We need to maintain the"referential integrity" between database and files.What I'm thinking of is something like this:1. stop the application server2. set database to readonly (flush updatesfrom cache to disk)3. backup database to disk files4. back up application files and backup files.(We could use "snapshot" capabilities of our diskhardware, so that the backup could run against thesnapshot; that would minimize downtime.)4. set database to read_write; restart app serverRecovery scenario would be:1. Stop application server.2. restore application files and database backup files3. restore database from disk backup4. restart application serverIs there a simpler way to get a "point in time" backupof application files and the database?

how can i store images in database? and how can i call them back?
please give me in detail.
thank you very much
If you serialize the image into a string ? If you want to save a byte array to a string, do you have to use a base64 encoded string ?

hi guys, are there any official or some sort of documents to talk about the advantages and disadvantages of storing image in the SQL's Image datatype field or storing the pointer to the image file? i have lots of static images (no more than 1MB each) that requires little updating and i need to retrieve them constantly. i am really struggled here on which method i should store the images: to store the images as Image datatype in SQL or save them as files and store the paths to the files. i would like to know, in my case, would there be any performance and efficient difference on using either method?
naturally, i'd think the 1st method seems like a better solution. it's easier to back up and it protects integrity. But at the same time, i am not sure if the constant inserting and retrieving of images will affect the performance? also, i want to share the images and may create a ticker thing (using JavaScript) to display the images on the web page randomly and it seems like the 2nd method is easier to program. if you were me, which method would you use and why? thanks!
I have a client who wants to be able to upload images to his website for his customers to access. It will probably max out at 100 images a month...so not a huge amount of data. I am using asp.net 2.0 and SQL Server 2005.
Does anyone have thoughts or opinions on why I should or should not take this approach?
I have a web server running fine together with an sql 2005 db. I use asp as my web server programming language and want to be able to display images that are stored in the database.
My question of course is how do I put images, for example an image called "image1.gif" into the database?
After having stored the images in the db, I guess that the are displayed on my web pages the same way as all text information (by writing something like <%=rs("image_column")%> ).... Anyway first I need help with how to store imgs in the database...
What is the type of values I have to use to tell the database to store pics?

Hi, for my photo album database I'm trying to decide whether to store the actual photos as images in the db or whether to leave them in file directories with just the path & filename in the db. As a beginner in this field I don't know how either of these options compare (e.g. in terms of performance, complexity, flexibility and maintainablity) so any advice on the pros and cons of each would be appreciated.

Dear All,
Is there any way to do things with filesystem in SQL 2005 ? I want to check a file and if exists I could replace data into it or create the file if not exists. I tried build a DLL file using C# to do those things and registered it in SQL 2005
but when I execute the procedure it returns an error like this below :
Msg 6522, Level 16, State 1, Procedure testfsq, Line 0A .NET Framework error occurred during execution of user-defined routine or aggregate "testfsq": System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.System.Security.SecurityException: at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.IO.FileInfo..ctor(String fileName) at FSQuery.fsq()
So, is that means that we can't use another namespace in .NET framework but Microsoft.SQLServer.Server ? thanks in advance.

I am having a problem with MMSQL BLOB with VB, Sorry to say I am new in Programming using VB 6 and MSSQL and I have never touch BLOB in my live.
I just wish anyone could give me any ideal, like, white pages, or manual on how do I insert BLOB data (Images) to MSSQL 2000 database using VB 6. I need to know exspecially the VB Code and the SQL Portion if you have a store procedure code for that it will be nice.
:confused:
The URL address is for example http://backup/pics/19980.jpg
On the report when I right click on an image the URL is http://localhost/reportserver
I do not understand what is going on. Please help.
Many thanks,

Hi.
I've been traling the forum and the internet for a striaghtr forward solution on this.
I'm trying to do what loads of people have already achieved: retrive images from an SQL database.
I have successfully uploaded inages to an "iamges" table, storing the image as SQL type "image", also storing size, type, description, name etc.
I want to be able to read one or more of these images (and other data) back from the table.
I'm using C#, ASP NET 2.0, SQL,
Any examples I've found needed a lot of tweaking, and for some reason or other didn't work!
Please don;t just pose yet another URL to an example - I've probably tried it and failed already.
I don't mind if I display the images in a GridView or just within an aspx page.
Ideally I'd be able to dispaly a few images on a page.
I know how to read and display the rest of the data in the "images" table.
Can anyone help please?
Do you need more info?
Thanks in advance,
Garrett

An odd question from me, I know, but this time, I assure you a twist.
I have a group that wants to store images in either a database or a file share, in order to make a certain website able to run on a load balanced web farm. These images are around 1KB each in size, and have a lifespan of exactly one use (think of graphs). I went a-googling, and found no shortage of articles that say "don't do it, but here's how you can do it", but I did not find any real hard statements as to why to not do it. Needless to say, this is hurting the case for not putting these images in the database. I have found an article that says images over 8KB will have worse performance, but I can not use that factoid here. For the moment, I have the developers leaning toward the fileshare, because they will be writing transaction logs all day, which will be more work than the fileshare needs to do....I think. The best I can do, is cut the text/image datatype overhead, and have them create the table as varbinary(2000), but even then, I don't like the look of the idea.
Anyone out there have good articles/whitepapers that detail the differences between writing single-use images to a fileshare vs. a SQL database? <baiting=blatant>Failing that, do any of the Microsoft development team have an opinion?</baiting>
Alternatively, what is the general opinion of keeping session state information in a database (because I bet that will be my next battle). I see .NET includes a session state server, but not being a programmer, I can not create an opbjective test.
Hia,
We have a simple table which we need to store logo's for a website. The table looks like this:
CLIENTLOGO (Tablename)
id (Bigint) (PK) - NOT NULL
StoredImage (Image) - NOT NULL
ImageSize (Integer) - NULL
Im not an expert on sql sorry!
I have two problems,
1. I need to upload some logo's (they are gif's if thats important)
2. I need to store the image size
I don't have a clue how to do 2 but ive tried the following for 1 but it doesnt seem to work
Insert into CLIENTLOGO (id, storedImageTablename)
Values (1, 'c:ClientLogo1.gif')
Can somebody help, im really confused about this one
Hello folks,
I am going to try to explain this as best I can. First off I have a single database within SQL 2005 and the table within the database has a field for binary image data. Currently this database has about 4,000 image records.
What I would like to do is recompress each of the images with new compression software called Déjà vu. What needs to happen in my mind is, pull the current binary data into the compression software, compress the image, then upload the binary data back into the same record as a batch command.
My question is can I do something like that via command line? Or is this something that will require rebuilding the entire database from the ground up? I like having the data all in one database for ease of
maintenance and intergration with other databases I am working with, so I dont want to just link the images.
Hi,
I want to view the images that are stored in a sql database. I am using VS2005. When I open server explorer and drill down to the dbase tables and the click on the show table data option the table is displayed in a new window.
when I open a table that stores images only a tag saying that the cell contains binary data is displayed. There doesn't seem to be any way to display the actual image and therefore edit the image. I can manipulate textual data directly in the database table...how do I edit graphics?
Thanks!
hi everyone,I'm currently developing a website and have a lot of images to use there(obviously :P), until now I have in some tables in my sql server db where exists a column which stores the path to: 'image folder + filename'And my question is: what are the advantages of using binary images in database instead of this approach to the problem, i.e., having images stored in a server folder.Thanks in advance.
