sql server 2005 - Designing Database for File Structure -


We are using the file system to store in the file. Now we change SOL2 to 5 to store it as Blob according to its requirement.

Now, we need advice about the design for the table.

I start with:

FileID, ParentFileID, should be a folder in the same as file system, file, size, last date modified, etc.

In the form, it is actually a good system for it already, and it is called file system - my first recommendation will be to see your needs again whether it is really required .

However, you may have your reasons, so here's how I create a table: 

  Filesystem (id, / / ​​fold field: 1 = file, 2 = folder, 3 = symlink, if necessary (?) Parent_id, // a folder file name id, modified, created, modified, created, file_data // blob)  < / Pre> 
 You will need a unique i (parent_id, filename) on Ndex if you want to emulate a real system They were 
 
 If you require per-file permission, then I just duplicate the Unix approach with the owner / group / each permit - you also have to track the owner and group_id in that table Perhaps you can make it master / simpler to everyone, and you can probably use reading / writing (for "execution").

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
