Question

How to store files in SQL Server 2000. Allow uploading files in Web Form.

Asked by: megnin

How can I allow users to upload "supporting documents" when filling out a Web Form?  
From what I've read, I don't want to store the actual document in the DB, only the filename and a link to the file in the Windows file system.
I'm using VS2008, VB and SQL Server 2000.  Thanks for suggestions, info or examples.

THAT WAY  YOU NEVER GET THE SAME IMAGE NAMED TWICE.

YOU DO NOT WANT TO STORE IT IN THE DATABASE BECAUSE THE LOAD TIME IF YOU HAVE TO MANY IMAGES THERE WITH BINARY WILL OVER LOAD SQL AND CAUSE YOUR SITE TO LOAD SLOW

did you read this inside the blog

In summary, there is no one right answer to where you should store your BLOBs. It all depends on the context. You need to consider the performance issues in the database and hold them up against the benefits of having your BLOBs stored in the database. A good

The documents will be mostly MS Word and Excel files, cost justification documents for a "Suggestion Box" type of form.  I only expect the number of suggestions per month to be in the low dozens and probably only a hand full of uploaded documents per month.

From that perspective, should I go for "easy" over "effecient"?  I'm a total beginner, so "easy" would be my preferrence.

 

by: sevensnake77Posted on 2008-12-09 at 07:45:18ID: 23130066

well it is the same way with the code above, just use .doc or .xls

 

by: megninPosted on 2008-12-10 at 12:37:27ID: 23142813

Does the code above have the files saved into the database or into the file system?  

It looks like the file system, but I can't tell for sure (hey, I'm a beginner ;-)
