Adding File Information To SQL Database On File Upload

Apr 18, 2004

Hi there :)

I'm in the final stage of my asp.net project and one of the last things I need to do is add the following file information to my SQL server 2000 database when a file is uploaded:

First of all I have a resource table to which I need to add:
- filename
- file_path
- file_size
(the resource_id has a auto increment value)

so that should hopefully be straight forward when the file is uploaded. The next step is to reference the new resource_id in my module_resource table. My module resource table consists of:
- resource_id (foreign key)
- module_id (foreign key)

So, adding the module_id is easy enough as I can just get the value using Request.QueryString["module_id"]. The bit that I am unsure about is how to insert the new resource_id from the resource table into the module_resource table on file upload. How is this done? Using one table would solve the issue but I want one resource to be available to all modules - many to many relationship.

Any ideas?

Many thanks :)

SQL CONNECTION - INSERT - RETRIEVE ID - Rename File - UPLOAD FILE

Sep 15, 2007

Hi there,
I have inherited a databse and am building a new website to go wiht it.
There is a file upload page which will upload images to a directory.  I need to insert into the database retrieve the id just added then upload the image renaming it in the format locID(QueryString)_ImageID(retrieved from database).jpg
The page has a file upload control and a button.
I am trying to write my code behind so that when the button is clicked it inserts location id into the images table retrieves Image id. Renames the file and uploads it to the images folder.
II think i need to call the routine from another routine for the button click but the signatures are different, where am i going wrong? or for that matter have i been pissing into the wind for the last 4 hours?

Upload File Only Works For Dbo

Nov 6, 2007

Hi there,
My problem is that the upload works in testing for our asp.net site only for dbo. Being mindful of security, I would prefer not use this account to execute all sp_/sql. One solution could be using impersonation only in the content management system where the uploading is done, this is code in web.config:
  <location path="Manage.aspx">    <system.web>    <identity impersonate="true" userName="dbo" password="****" />      <authorization>        <deny users="?" />      </authorization>    </system.web>  </location>
To do this I would have to change the dbo password as set up by previous employee, not a real dba so not sure of the implications (enough permissions to be dangerous though;). Is the above impersonation ok, or should I redo logins security in sql? Thanks.

I appreciate your help and suggestions and any tips & tricks or issue that I have to consider.

Flat File To DB Upload Approach Question

Mar 2, 2007

Hi guys,

Suppose I have a flat file that had columns that went like this:

rackId, cdname1, artist1, year1, cdname2, artist2, year2, cdname3, year3, artist3,...cdnameN, yearN, artistN

And I want to map it to a table that has the ff columns:

rack_id | CDName | Year | Artist

Assuming that N is constant and all rows of the flat file will have N or less values filled up per rack, how do I map the fields from the flat file such that cdname1, cdname2 and cdname3 all fall under the CDName column, year1 and so on will fall under the Year column, and artist1 and so on will fall under the Artist column?
