Suggestion on using image data type in sql 2005.
-
Dear Shameel, First of thank you very much for your time to reply. Actually its not an file storage its an data storing.. say for example i want to store the details of an employe like name, age,sex ,address,... and his/her PHOTO... so here comes the image plays the role.. so this is the requirement. am bit confused to use the general MSSQL server to use it from internet as it will create problem by perfomance..or something. thanks
Information like name, age, sex, etc. can be stored using appropriate data types like varchar, int, etc. Photos can be stored using two ways: One is to store the photo as binary information in an image column. The other is to store the photos as jpeg images on the file system and store their paths in a varchar column. Each of these approaches have advantages and disadvantages of their own, you may want to explore these options further and see what works for your situation.

once again thanks to you and shameel for your time in replying. as you peoples mentioned i can save the file in the web server. But as i mentioned earlier i will be using the windows application to save the images and i will retriving the same in windows application. In that case i need to share the folder (to all the machines ??? ) rt..it may cause security violation.. so there is only one way to store is database rt? so i need to compromise the perfomance of the applcication...

No, you don't have to and you should not. You can build a web service that serves images. Google can help you find code samples to get you started.
thanks shameel.. i will check that case and get back to you.. thanks in advance

Dear All, My requirement contains an windows application that can be installed any where over the world but the server will be in one place which will be accessed via internet. Note : the same db will be accessed from web application also for reporting. I plan to use MSSQL 2005 version and my db has image datatype also. i am using the image data type in the db, when i try to query this it is taking more time for replying... is it advisable to use the same? or is there any way to accomplish the same by using any other data types.. i tried usign varbinary (max) now the perfomance is little better than that.. but still slow. Please guide me . thanks in advance.
You may want to look into writing a Web Service (WCF) and access that from your clients. I agree with putting the image in the database (I don't trust the file system), but you should only access it when you need it, not every time you access the record. I also suggest you put the images in a separate table.

It's slow because you're fetching a blob from the database. Host it on a webserver and store the path, you'll find that the browser simply caches the picture.

And where do you persist your database? Even if it is on a good old magtape, that still probably implies a file system of some kind. :)

Agree with other 3 members. Also I prefer Filesystem instead of BLOB. Check this post, explained things clearly. Storing Uploaded Files in a Database or in the File System with ASP.NET[^]

Trusting it not to lose one big file is one thing, also trusting it not to lose many small ones is another. (Easier to back up too.)
